This is an export from a piece I’m working on. There are 4,096 blades of grass with about 15 circular segments per blade. The are built with VBO’s running at about 50fps. I would love to get a few more FPS with some optimization. The ground and wind react to sound input.

    Is it perlin noise that you use for the wind?
    Very, very nice!!

    Yes - Noise is the main drive and the sound effects the noise flow. I found that just using the fft to drive the grass looked to mechanical.

    hi todd! I just found this paper which can be of interest for your grass animation: cs.virginia.edu/~gfx/pubs/antimony/ it's an algorithm for nicely distribution of you grass thingies.

    Wow, amazing. I'm intrigued to know why there are 'about' 15 segments per blade. Does it vary from blade-to-blade?

    Looks really good.
