Here's a sample showing the feedback loop on my new patch. As I mentioned in my last blog, it was a happy accident. This patch is fairly flexible. I'm only using about 3 of the parameters I put in, and there are a lot more. Hopefully that means I'll be able to vary it up enough to keep things engaging for the full night.

wow. this was really looking great.
so what does the patch exactly do?
still haven't found time to dive into jitter, although i now own it for nearly 1,5 years. what a waste

Lovely stuff. What kind of steps did you have to make to get your patch moving more of the number crunching on your graphics card (did i understand that right?)

Here you're basically seeing the patch generate vertex points for a NURB (which is manually controlled). The shape uses 2d video as it's texture which can also be viewed as a backdrop, or, if I pull the nurb alpha channel down, the patch can be solely 2d. I'm able to manipulate both the 2d elements which affect the NURB texture, or the NURB geometry/texture coordinates themselves. I think there are parts in this patch where you can see me modulating the vertex points with a noise matrix which makes it wiggle. This new patch allows me to capture the entire scene back to a texture and do post processing on everything.

Anything that is in the opengl world (3d shapes, textures, lighting, fog, etc) is done on the GPU unless you specify that you want to process it as a matirx on the CPU. You basically have to figure out how to pass the graphics card data in a way that it looks like it's one of those elements for it to do anything with them. This patch mostly maps data onto a slab and then uses a mix of custom and pre-existing shaders to process the data.
