Showing posts in "Simulation" category:
When a star brightness changes suddenly the scattered light from the surrounding cloud does not reach us all at the same time. It is delayed based on the total distance traveled and the speed of light. The result is called a light echo. To better understand how a light echo works I created a simulation of one.
One can create spiraling motions for particles using expressions. This method propagates a local up vector for the curl so that the twist direction does not go through pole flipping as the particle changes direction.
As promised here are the scene files from my Unfold presentation along with some brief descriptions.
I've modified the roman candle scene in my previous post to use lights positioned at particle locations for illumination, along with further refinements.
