LEDBoard EQ Project

Thanks to some basic tips from Jph, I was able to create this. Just wanted to share, but It runs a little sluggish in ZGEviz. I use a 16x16 opacity map on every block. That seems to be the cause. I'm not sure how to fix it. I used a direct manipulation of that to control a "intensity" parameter. It still renders nicely though.

Feel free to take this and use it how ever you like too.

Edit: Forgot to mention this requires a 128 band setting. Ville mentioned a way to fix this, but I wasn't sure about how to implement it.

Yikes, that's about the most unoptimized way you can set something like that up. You don't want to use Models for this kind of thing ( plain Arrays are much faster ), plus you only need to render 1 to 3 quads per band ( instead of 48 ). Neither do you have to DDA through your grid, simply lerp between the different bands ( when you're not using as many LEDs as your SpecBand ).

Nice effect nevertheless

Yes - brute force indeed. I don't often think about optimization at all. Just too lazy & lacking experience in that area. For personal use it's ok, for me. I need to start focusing on efficiency, to develop user presets though.
