SDK : FBVideomemory, how to use OpenGL functions

2013-05-15T21:44:08+02:00

Hello, I want to use FBVideomemory class. But i cannot understand how to use, because i cannot generate OpenGL texture ID. "glGenTexture" function returns error "INVALID_OPERATION". I tried following source code. glEnable( GL_TEXTURE_2D ); glGenTextures( 1, &id ); <- here is problem glBindTexture( GL_TEXTURE_2D, id ); glTexImage2D( ... ); glBindTexture( GL_TEXTURE_2D, 0 ); mVideoMemory->SetObjectImageSize( width, height); mVideoMemory->TextureOGLId = id; mMRCamera->LeftCamera->BackGroundMedia = mVideoMemory; This is very cheap question i think, but i'm a beginner. Does anyone have any idea or know good reference? Thank you,

29.97fps playback

2013-04-24T11:49:53+02:00

I'm currently working with some mocap data (C3D @120fps) and reference video (raw QT @29.97fps). Each has embedded timecode that was generated from a common external device. When attempting to set the playback rate, I noticed there is not explicit option for 29.97fps. So, I selected custom and entered "29.97"...which displays as "30 fps" in the drop down when set (seems odd). There is the NTSC Drop option, which is a 29.97 rate that is achieved by dropping 2 frames every minute (as far as I understand it) but the video uses a non-drop format. Anyway, I've lined the timecode up at our slate frame, but progressing through the timeline thesync shifts by about 2 frame over about 1 minute. This seemed to match the drop frame equation, but I lose the sync whether I set playback to 29.97, NTSC Drop, NTSC Full or 30fps. The only difference is they lose sync at different rates. * So I guess my question is this... How accurate is the "custom" 29.97 playback rate? Why does is show as 30fp once set? Why is there no explicit option for 29.97 (non-drop), particularly when there is a 23.976fps option? I ran across this while hunting for answers - http://download.autodesk.com/global/docs/motionbuilder2013/en-us/index.html?url=files/TOPIC_BAA746B1168B44648F67118EA9336444.htm,topicNumber=d30e8686 Could this still be an issue even though we're running 2013? I'm relatively new to this, so any wisdom on the subject would be much appreciated... Thanks.

Invisible Camera

2013-04-18T18:34:01+02:00

This is the noobiest of all questions, and I apologize for that. I'm new to MotionBuilder 2013 and have found that when I insert a new camera into the scene, it is invisible, though I can see its transform controls. I have tried cycling through the Display options and checked to make sure the View settings are checked in the Camera Settings, but the camera is still invisible. Could someone out there please let me know what I'm doing wrong? Thank you so much for your time!

Parent Space Scaling by constraint

2013-04-16T02:53:56+02:00

Hi, I'm trying to reproduce the parent space scaling behavior with a constraint - when I link an object to another one with a different orientation and I scale the parent while the child is configured to scale in parent space I get the same 'global' scale as the parent with some shearing. I have tried to reproduce the same thing with a constraint but the constrained object always scales locally. Does anyone now if there is a way to get this parent space behavior with a constraint ? Thanks!

Speed up Filtering

2013-04-16T02:39:39+02:00

Hi, we have a lot of 10 minute long takes of optical motion data with 36 markers. to process it we filter with butterworth filter. i takes quite some time to do so.. although the machine is not that slow and has 12 gb ram. what are the system requirements to speed up filtering in motion builder? is it mainly cpu related filtering ? Thanks in advance, Daniel
