I want to use Processing for a visualization of a 3D search algorithm. There are 1000 points in 3D space, and I’m rendering them with spheres. So far so good. I now want to place a second, larger sphere around the first point, and I want the second sphere to be transparent. This is where things get funky.
Now, there is a ton of overlap, and I’m not surprised that the result is weird. But the result is really weird in ways that I’m not sure how to fix. I tried mucking with the blend mode, but I didn’t have any luck there. I get that a whole bunch of overlapping transparency is gonna add up to opaque, so I’d love any suggestions that you might have in how to get this working.
