Voxels in the wind

Fall is here and it is getting windy. It is a good time to finally add some animation to grass blades and tree branches.

 Here you can see some results:


There is nothing fancy going on here. The post title is deceiving since no voxels were animated, just traditional polygonal billboards. The motion is a few sine waves overlapping at different frequencies. The next step is to feed wind vectors to the vertex shader. This will create turbulence near cliffs and some other nice effects.

And then some leaves and other particles flying around for increased realism.

Talk Points

I just found out the audio for my talk at the Mont Royal Game Society was very poorly recorded. It seems the only way you will hear this presentation is you invite me for beer. Anyway for what it is worth here are the slides. They were designed to go with the talk so there is a lot missing.
