Well, I've moved triangles made with the mesh creator in the past but what seems to be a problem here is using the mesh creator in point mode, and then sending that data to the mesh renderer. If I change to triangle mode, this works. gl_Color is passing along fine in the fragment shader.
In the vs, I'm getting the length of a texture and moving points that should have a z of 0 by adding the texture value (not multiplying) to the z lane, ala typical extrusion height field. This is a kinda complex composition that sets up a fluid sim via texture, passes that along to a kernel that computes a particle sim. I thought it would be cool to just extrude the particle sim with texture and add ao using a shader.
