Hi. I recently tried Processing 2.0 and I've noticed something I love. If I draw 3d points (OPENGL or P3D), their apparent size changes with perspective (Instead of being a fixed number of pixels). They are also round.
Does this come from OpenGl 2.0? or is it particular to the processing implementation?
I'm in the process of learning pure openGl and points don't behave like this normally. If it's a processing implementation (like substituting points for circles or something like that), it is pretty fast. If it's an openGl feature, does anyone know how it's used?
This takes point clouds to a new level for me (Without having to get into textures).
Hi, whenever I use the getAvg function to plot an FFT, the first 3 bands are always on, regardless of the frequency I start in.
I would expect the first couple of bands in the very low end of the spectrum to be always on (At least that's what I get on my PC), but when I use getAvg(440,12) I'm supposedly disregarding anything below 440hz. So why am I getting this buzz on the first bands?
