Now I want to transition to 3D but thick lines look terrible in P3D and strokeCap does not work at all. I've looked into replacing the lines with boxes or other 3d primitives but I can't figure out how to use the translation/rotation system in my case.
I did not use it in 3D as my algorithm generates X1,Y1,X2,Y2 coordinates for my lines. Changing the way it works would be more trouble than it's worth
How can I use the lines as a guide to "wrap" them in some 3d objects? For example I would love it if I could write box(X1,Y1,Z1,X2,Y2,Z2,WIDTH,HEIGHT) and create a box or cylinder around the line.
