I have recently been experimenting with a “grass” opengl vertex shader that allows the player to move smoothly though a patch of grass with the blades flowing around the player. The file seems promising but i’m not sure if its just a dead end because the fps drops significantly. I read about VBO’s and Geometry shaders. They seem to be key to opptimizing the blend. I’ve looked into other builds that have geometry shader support. Builds like Harmony, and moguri’s old gsoc build. I even found some patches some other BA users have made. I cant get a single one to work. If somone who has experience with this please help me with a most recent build of blender with a working geometry shader. Also if it isnt to much to ask a working passthough shader in order to get an idea of the setSource() api, if needed.
here is an image of my grass blend. i will post the file soon. i want to make a good example blend.
