Whenever I draw a polygon using opengl the edges look bad because straight lines look bad. I want the edges to have nice soft antialiased edges but that's not how opengl draws polygons. Multisampling AA doesn't help as much as I expect it to.

so we have this shaders, i wonder how close are they to what you have in mind? https://github.com/solvespace/solvespace/blob/master/res/shaders/edge.vert …https://github.com/solvespace/solvespace/blob/master/res/shaders/edge.frag …

Smoothstep is a very poor mapping from distance to area. Common mistake. Even linear interpolation is better. (I posted a graph a while back.)
