Stereoscopy in 3ds Max with StereoCam Modifier
Posted by Louis Marcoux, 2 December 2009 7:00 pm
This week, i am posting the videos that i have prepared for the 3December event. The blog post covers a wide range of knowledge on making stereoscopic CG with 3ds Max. And, most of all, you will learn the basics of making comfortable CG Stereoscopic images by taking the projection setup into consideration.
3December Event
The 3December Online event was held last week and 6 master classes were made available for your viewing. You can find very interesting presentations visiting the dedicated page on The area:
http://area.autodesk.com/3december
There is a couple of 3ds max presentations including one from Liquid Development on the assets development for The Beatles : Rock Band game. My colleague Eddie Perlberg also does a presentation from the show floor at AU.
3December happens every year on that date and you can find tons of new material on the Area and you can attend live events in various cities around the world.
Stereoscopy videos
In order to make everybody aware of the videos i have produced for 3December, i decided to include them in this blog post. This way, long after the event will be over, you'll be able to refer back to those videos and use them for your stereo production. Also, because there is a comment section at the bottom of the page, we'll be able to continue the discussion about stereo and how to achieve great results within 3ds Max.
The videos are the most recent ones i have produced on stereoscopy. They contain new learning and concepts that i have never covered before. So, i hope you will be able to learn something new from them. I know that there are a lot of Power Point slides but those videos were intended to be a master class and it was the appropriate format for this presentation. I hope you won't mind... But don't worry, there are 3ds Max examples in there too...
At the end, you'll see that i use a Max Script that i wrote to make stereoscopic shots. The script is included below and you can use it/modify it as you wish.
Basics
Overview f the basics concepts related to stereoscopy. It's a good refresher before getting into the technicality of producing stereoscopic images.
Projection Technologies
A very brief overview of some of the technologies available today for viewing stereoscopic images.
Comfortable Stereoscopy
In this video, i review all the considerations that needs to be made to produce comfortable stereoscopic content.
Comfortable Stereoscopy | Practical Example
In this video, you'll use the rules of comfortable stereoscopy to produce a stereo image for a given setup: my office...
Stereoscopy as a Story Tool
Here, we'll see how stereoscopy can be used as a tool to better tell stories because, like many other camera effects, stereoscopy can generate emotional responses with the audience.
Stereo Camera Modifier in 3ds Max
This is the instruction manual of the 3ds Max modifier called "Stereo Camera". I wrote this modifier for my own use but you can download and use it in its current version by following what is explained in this video.
You can download the Max Script here:
userdata/fckdata/4952/StereoCamModifier_V1_7_3.rar (updated on july 25th 2011)
Please note that this script is not supported by Autodesk. If you find issues and limitations, you can let me know in the comments section and if i have time, i'll try to improve it. But, there is no guarantee that i will respond to every wishes that are made. If anybody else wants to work on the script and improve it, you are more than welcome to do so and share with us!
notes on june 15th 2010 update (V1.7.2):
- added Toe-in vs Film Offset slider to blend between the 2 convergence methods
- fixed the vertex error in languages other than english
- made the anaglyph preview faster
- added an option to unhide the cameras for rendering setups that have issues with the skew modifier when cameras are hidden
- added an option to see all the camera frustrums
- added color options for the colored filter glasses (you choose which colors to use for left and right channels depending on the glasses you have)
- option to preview in grey mode or original viewport colors
- added a "setup batch" button that adds the 2 stereo cameras as views in the batch renderer dialog (important: if you press this button while the dialog is opened, the views will not update. Close the dialog and reopen to update the views that have been added)
notes on July 25th 2011 update (V1.7.3):
- Force a complete viewport redraw so that the preview function works in the new Nitrous viewport (2012).
- Made the stereo zone's materials 2 sided so that they can be viewed correctly in the new Nitrous viewport (2012)
Viewing Stereoscopic Animations
This videos covers a few techniques to produce content for stereo viewers.
Conclusion
Few conclusion notes.

For real time preview, someone suggested to me to write a screen fx shader but i have no experience in HLSL so i won't be able to make that happen. At least in the short term. If anybody knows how to do this, let me know...

I took the liberty to customize the preview buttons into two different buttons wich lets you pick either red/cyan or green/magenta depending on what type of colours your anaglyph glasses have.
Quite easy if you have basic knowledge of MAXscript!

For the german version, i would need to review the script and see where that breaks... I am a bit suprised, it's like if the properties were also renamed in versions other than english...
Make sure you are on 2010 because i used some 2010 specific scripts improvements for the script...
And the script is there to be modified. I appreciate your input egz. It's great to see that the script is readable enought to be modified and adapted by others...

I not sure if the same set of rules applies to parallel shooting as with convergence shooting, because it would be nice to have all the visual zone indicators showing properly.
If working with CG-3d integration many production companies resort to parallel shooting the live action because of the time saved and easier/cheaper setup.

Hi Louis. Excellent script, just a few suggestions as follows.
1. In your next update any chance you can add another zero to the upper range limits for Viewer Distance and Horizontal Size for those of us who work in metric units (currently only 1000, needs to be bigger e.g. 10,000), 1000mm is not very long.
2. Stereo camera object only works properly in the viewport in DirectX9, for some reason when using DirectX10 it makes the comfort zone objects one-sided so you can't always see them, tried changing transparency quality but it does not make any difference. Not a major problem, just thought i'd let you know in case people are having display problems.
3. The following would be my priorities for further development i) a proper Target Camera option, ii) sorting out the problem with leftover parts when deleting the base camera, iii) the ability to vary the range of the comfort zones

Any, my stereo rig in the script is parallel and i "trim" by offetting the register plate with the skew modifier.
For real life matching, i would encourage you to build a more sophisticated rig where you can adjust each camera individually and be able to rotate them up/down to repest the errors introduced by real life cameras.
Nedsknees: You are right about direct X issues. I face the same issues here. I think i will explore other options to display comfort zone. Also, all your suggestions are good. If i find some time soon, i'll try to update the script with some of those... I have a "to-do"list for that script that is growing up! For the comfort zone variations, that all depends on the interaxial and the convergence plane. But i want to introduce the concept of "stereo budget" which is quite common in stereo 3D productions. So i want to allow users to plan a depth budget and see it in the rig... Another thing on my list...
Thanks for all the comments.

Side-by-Side video stream is easy to reproduce in any compositing software like Combustion or any other Autodesk Compositing solution. It's just a matter of putting the two images side-by-side and scaling them by half (horizontally) to make them fit in the output resolution.

It affects the camera view in vieports but not in renders.
That's what everyone is experiencing.
If you turn of skew modifiers on the left an right cameras the anaglyph preview looks like the renders.
Does anyone have an idea why this happens?

By doing these tutorials, my intend is not to be a tools developer but to give you the knowledge to expand and build your own work techniques. When i learned about stereoscopy, i decided to write that script to help me setup the cameras since it was always the same maths to perform and i got tired of repeating the same maths over and over again... But, i will reiterate what i said in the text of the tutorial: " I wrote this modifier for my own use but you can download and use it in its current version by following what is explained in this video. Please note that this script is not supported by Autodesk."
I want to continue to work on this script in my free time but i can't make any commitment. I take notes of all your comments because they will help me build a better tool when i have the time to do it... But, if you want to modify the script and improve it, please got for it!!! And if you can share your findings, even better!!! I know someone else did and it's a very cool setup (look in the comments to find who and where you can find it).
Anyway, just to reinforce that if the script doesn't work on your setup, i suggest that you look at the videos again to build your own manual camera rigs. It a great learning experience and maybe you'll come up with better execution techniques than mine.
And, please, share your findings!!! They will be useful for everybody.

In the videos, i explain the full maths behind how you need to preserve the ratios between different virtual elements and real life elements (cameras, distance, etc). The maths can be overwhelming and a bit too precise... If you make an average of all of the common projection setups (home, theatres, computer screens, etc), it goes close to 1/30. So, when you want to do it quick, it's a good first estimate for many projection setups. But when you start to project of very big screens or untypical projections setups, that's where you need to be a little more careful and use precise values.
The rule of the 2 degrees. More maths to be more precise...
In the videos i have built here, i don't talk about a fundamental rule of tolerance for pixel seperations. Some studies have shown that from the viewers point of view, a pixel seperation of more than 2 degrees becomes uncomfortable. If you make a rough estimate of where this happens in the 3D scene, it correspond to about half the distance between the convergence plane and the cameras (and same distance beyond the convergence plane) when all the ratios are being preserved. That's the assumption i make to simplify the setup and the maths but if you want to be super precise, you can use this 2 degrees rule. If ever i get some time to re-work the script, i will probably use that rule instead to be a bit more precise when defining the comfort zones in the scene.
But in the end, when you look at a stereo image, you need to follow your intuition. If you look at an image that respect all the rules and that should be comfortable but isn't, then readjust the interaxial and reduce the stereo effect. If you want an audience to watch a long movie in stereo, you need to make sure they don't get a headache before the end...
I have gathered so much comments and suggestions from this thread and emails that when i will get a chance, i'll work on V2.0 and improve it... Now, with 3ds max 2011 being out, i am super busy but i'll try to get some time soon to make a few improvements.
For those using 3ds max in a langage other than english, there seems to be an issue with certain properties not being recognized. I'll investigate on that aspect to find out how i could work around that.
Thanks for all the feedback.

Posted 15 April 2010 3:33 pm
very good answer.
but.. i`m little curious - why "rule of the 2 degrees"
as i know - there is "1 degree rule"
http://www.stereoscopy.com/library/waack-ch-4.html
it`s mean that degree must be less then 70` (minutes)
70minute=1.1degree
Louis Marcoux
Posted 15 April 2010 3:46 pm
So, essentially, you imagine a line between the screen and the viewer. Pixel seperation on each side of the line should have a maximum on one degree. Total: 2 degrees.
It's a very interesting rule because it quantifies the comfort zone a bit better than the "half distance" approximation.
But again, it's all about human perception. Some stereo might work beyond the 2 degrees rule and some stereo might not work even within the 2 degrees rule.

Yes, it is fully normal that the camera's FOV is being affected by my scripted setup. What i am trying to do with this script is to replicate the exact physical conditions of the image being projected on a screen and seen from a viewer at a certain distance. This is crucial for good stereoscopy. If you don't take this into consideration, you end up with very random results. Our main goal when making stereo images is to make it comfortable.
If a user watches a screen from very far or very close, the FOV of the viewer (of that screen) is not the same. If you think about it, the image on the screen stays the same size but as the viewer is walking back from the image on the screen, the image start to appear smaller, reducing the FOV made by the triangle "screen left side - screen right side - viewers's point of view".
Stereo might work very well when a user is far away from the screen even if pixel separation is high. But as the viewer gets closer the the screen, the pixel separation appears bigger to the viewer and can become uncomfortable.
So, my script reproduces the real physical setup into the virtual world in order to give you an accurate representation of what will be possible to do in stereoscopy within that scene. I calculate the FOV based on the distance of the viewer from the projected image and the size of that projected image. With that setup in your scene, you're able to make quick decision about where to place things and how to scale the rig to make your scene work.
Working around the physical FOV
If you want to cheat the FOV, you can change the projected image H size parameter in the modifier. This will affect the POV. Also, if you reduce the viewer's distance, it will also increase the FOV. But remember that if you do that, you will no longer have a physically accurate representation of the projection conditions. So you'll need to do a bit more "eye work" to see what works and what doesn't on your projection setup.
Images
If you guys have images to share, please send us links. It's always cool to see what other people do.
Louis Marcoux
Posted 16 April 2010 2:39 pm
So, if you are working from these types of cameras, i would suggest you discard the script and that you create your cameras manually and rig them together so that they follow the same animation (link left-right cameras to central camera and same with camera targets). Then, either you toe-in your cameras to have the same target (introducing some problems on the sides if the toe-in angle is big) or you use the skew modifier to make the camera frustum converge (to avoid problems on the side). See the "comfortable Stereoscopy" and "comfortable Stereoscopy | practical example" videos (above on this page) for details.
You need to reduce or increase the interaxial until you reach the depth level and the level of comfort you desire for the shot. If you are good with trigonometry maths, you can calculate your comfort zones based on pixel separation tolerance for your projection setup or you can make a quick approximation with the 1/30 rule. That means: place your cameras at an interaxial distance of (1/30)*(distance between convergence plane and central camera).
My script is there to create a simple setup that has predictable comfort zone and convergence plane within a 3D scene based on a physical projection setup. Your approach is different and needs a different solution. If you Google "stereoscopy" and "calculation table" for real life lenses, you will find tables that will help you with this calculation. I know that there are a few free ones out there.

Make sure you watch the videos on the camera rig (practical example). The script is there only to automate that process.
The preview button will work in 2010 and 2011 but not in previous versions. It takes a snapshot of the viewport and makes a quick anaglyph preview. It's not a rendering.
Regarding animations: depending on the effect desired, you can animate the stereo setup. But this is not going to be comfortable and it will be hard for the viewer. Please review the video on how to use the screen as a puppet theater. It explains why those settings need to be fixed. Stereoscopy will be comfortable if the brain is able to understand what it is seeing. By animating the interaxial, it's like if your eyes were moving away/towards each other which is hard on the eyes. So, my recommendation would be to be careful with animating the parameters of the modifier.
Louis Marcoux
Posted 26 May 2010 2:29 pm
The skew modifier, as i explain in the videos, is there to offset the camera frustum to give the same projection effect as the film offset. Different wording, same effect.
You can mathematically calculate the film offset (from the maths i used in the script to calculate the skew value) if you really want to have that value. The offset is in mm and virtually represents how much mm you have to move the film in the gate to be able to capture the proper projection from a flat projection plane (no toe-in) and converge to a specific point. But the projection result in my script is the same as doing a film offset in mm.
My script has been created to simplify the calculations needed to create a comfortable stereo rendering. It's all about reproducing real projection setup and relationships to make sure you are working with controlled stereo zones and know where things will physically appear to be when viewed in stereoscopy.
Cyromus and others using the script in a 3ds max version using a different language than English: i am investigating why max installed in other languages than English cause problems with the script. If i find a solution for this, i will post here.
Louis Marcoux
Posted 26 May 2010 7:44 pm
i updated the script so that people using 3ds max in another language than English can use it. Please let me know if it works for you now.
Use the link in the text of the blog post above. You'll see that it is now V1.4 and that it has been updated on May 26th 2010.

Posted 31 May 2010 5:53 pm
Mikfr83-> i don't know if you have changed anything on the rig after you have applied the script. But i have tested on 3 machines for all the 3 renderers (Scanline, MentalRay and Quicksilver) and it renders correctly. Try a new scene with a new camera. It probably is something you changed on the rig or maybe you are not using one of the native renderers. In the last case, there is not much i can do. You'll have to check with your renderer's developers to see if they can support skewing the camera.
Louis Marcoux
Posted 31 May 2010 8:43 pm
If it works when you render manually, then something is happening where the skew is not rendered. That's what worries me.
Try creating your own skew modifier and then render with batch to see if it works or not. I'd like to know if it's the skew modifier itself that is the issue or the script's automatic rigging that gets something wrong.
Here it all works fine but i use the English version of 3ds max.

I work only with English version of 3dsMax.
Apparently the problem come only with your automatic rig ("Stereo Camera" modifier).
I've made my test with scanline & vray render (max 2011 & 2009)
When I create a rig manually (like your "Practical Example" video),
the skew modifier run correctly and all types of renders are ok!
Kind Regards,

Posted 1 June 2010 1:12 pm
If that solves the issue, i could add an option to hide and unhide the cameras like the comfortable stereo zones.
I created "eyes" geometry to give a sense of scale to the camera setup. By looking at the eyes and the camera setup, you have a good understanding of it's similar to the real world setup. But i could add the option to unhide the camera too so that it renders ok.
Let me know if it changes anything on your side. Like i said, here, on 3 machines with 3 different renderers, it works. So i need your help to figure out where it breaks.
Thanks.
Mikfr83
Posted 1 June 2010 2:29 pm
Just unhide and it's running!
Maybe in your script, unhide the cameras by default or an option like you say.
Thanks Louis!
Louis Marcoux
Posted 2 June 2010 3:04 pm
Also, i added a few other tools...
1) ability to show and hide the camera frustrums from the modifier
2) ability to change the color filters for the anaglyph preview therefore allowing you to preview with different types of glasses
3) a "setup bath" button that creates 2 views for the left and right cameras associated to the current modifier

Louis Marcoux
Posted 2 June 2010 3:11 pm
But, that being said, i would say that rules are there to be broken. So try it with your scene and see if it breaks or not. If the move is subtle and it works, why not. In a 2D movie (flattie), Hitchcock (and others) did really interesting camera effects by dollying the camera and doing a zoom to maintain the framing through a camera shot. The result is disorienting but also very effective. Animating the interaxial distance will be disorienting but it might give you the effect you want for the shot.
So, my advice with stereo shots like these it to try and see. Watch it the the context of other shots and see if it is comfortable to watch.

Stereo can be very effective even if the pixel separation is not that big. So you can reduce the interaxial without worrying too much. It's better to be comfortable than hard to watch...
Doing it at compositing stage is possible but if your objects are spread into the 3D space (depth), you'll have more issues to make everything work. Better plan to do it in the 3D scene. Then, final tweaks in composite if needed. In that case, better work with render passes for front, back and middle to have better flexibility.

Unfortunately, the Kostasoft utility is not opened to scripting so there is no way i could automatically connect it to the cameras in my script. It would have been nice but for now, if you use both my script and Kostasoft, you'll need to setup the cameras manually in the utility panel for this tool.

Also, i like the clear description you do on your blog on how to use the real time preview with 3D Vision.
Everybody should check this out. It's really well done!
Thanks for sharing.
note on reflections: If you have objects reflected in your visible objects, you need to consider the distance of the ray going from the camera to the reflective object then to the reflected object. If that distance is outside of comfort zone, reflections will not be comfortable. Reflections are point of view dependent and, therefore, when you move the camera, reflections will change. So, check that total distance and if it's too big, then reduce your interaxial until you get that total distance within your comfort zone area.

re: Unknown property: "EnableButtons" is undefined
This command is DirectX only. If you are using OpenGl as your display driver, it will not be needed. Just comment this line or delete it from the script. It should still work.
re: Vray
This script is for Scanline and Mental Ray renderers only. Vray cameras are different so they would need their own script to work in a similar way.

Check the name of the camera. Don't use foreign characters or hyphens in the name. It's a bug from MaxScript, not the plugin.
And I didn't check the consequences, but I think it's a bad idea to rename the camera after the modifier is applied.

i will be updating the script soon with a version where the preview works in 2012. The script needs to force a redraw of the viewport in the new Nitrous Viewport (ForceCompleteRdraw() command). It's 2 lines of code that i added in the anaglyph preview function and it works. I will upload soon and put on this page.
@Chill3d: I would recommend using a viewer that takes care of taking 2 streams and displaying them side by side. That or use 3ds Max Composite to do exactly that: put the 2 images side by side.
For playback tests, i use this player: http://3dtv.at/Index_en.aspx. It has multiple display modes and it works great. If you use it in public, you need to buy the license but for personal home tests, it's free (and great!).

i have uploaded a new version of the stereo cam modifier script (V 1.7.3). This version will preview correctly in the new Nitrous viewport (2012).
Enjoy!

thanks for the great script.
Here's a tiny suggestion for improvement: Specify the default values for world unit parameters such as interaxial etc. also in world units. Right now, interaxial is set to 2 units, whatever they are. Instead, you could use something like
units.decodeValue "6.5cm"
to plug in the correct physical dimensions. If I read your code correctly, this needs to go into several places, amongst which is the
on BTN_ResetReal pressed
event handler that could probably replaced by a single line using the above function (and probably the other occurrences of "case units.systemtype" in the code)?
Also, this would allow for "one unit = 10 cm" for example

Oscar: The script should work on 64 bits. Just copy it on all the machines you need to open the file on. Also, you can create a stereo camera rig following what is explained in the videos. The script i wrote just to automate and simplify the process. But for customization work, you can either edit the script and change it to your needs or build a camera rig that can be used in your environment.

très bon tutoriaux.
alors voila ma situation: je travail sur un projet de teaser de docu-fiction en stereo.
je suis pas mal perdu dans tout ça, il vas falloir que je m'y retrouves. mais au delà de la stéréo dans MAX, je vais avoir à faire des incrustations sur plans filmés. alors est-il possible de m'en dire plus, ou de me dire ou en trouver plus, sur l'integration d'elements 3d sur images filmées le tout en stéréo (images filmées avec une camera stéréoscopique apparemment) du coup j'imagine que certaines valeurs me seront imposées par les settings de la camera réelle, comment ça marche?
ton plug-in est-il utilisable dans ce cas?
et enfin, est-il possible d'utiliser le système métrique avec ton plug-in?
je te remercie par avance, j'en ai vraiment besoin.

Pour le tracking stéréo, ça prend un outil de tracking de caméra. Avec 3ds Max (subscription et suite), on offre Matchmover. Mais Matchmover n'a pas d'outils dédiés au tracking stéréo. Tu dois tracker les 2 caméras indépendament et ensuite faire des correspondances de points visuels pour mettre les 2 caméras dans le même context de référence spatial. Il y a aussi des outils plus avancés qui ont des trackers stéréos. Mais je garde ton idée en tête pour un futur tutoriel. C'est une bonne idée!

Thank you for the script.
I am working on a stereo project in Maya but using Max doing effects. I am planning to bring Maya's stereo camera into Max and use your stereo modifier to re-create stereo effects. But I don't know how to connect zero-parallax from maya's stereo camera to scale% setting in stereoscopic effects. Is there a way to do this?
And in Maya's stereo camera, there's no settings such as horizontal size and viewer distance. Would they affect anything when images rendered in Maya and images rendered in Max finally composited together?
thank you in advance for the answer

This is a very very powerful script.
But I'm got a situation is 3D screen without glasses.
And I'm need duplicate 8 cameras in between stereo distance.
Could you please update this script for us to use?
Very very thanks your help.
