CyberVGA update.
I've just finished implementing screen spaced grass effect in my octree renderer.
It works only with materials tagged with "terrain" and it generates and distributes grass blades on the fly using screen spaced 4x4 Bayer Matrix as threshold, for now a hard-coded density parameter, global wind vector for animated sway effect and triangles' UV for screen placement and 1/z information for perspective correction.
What do you think?
