perhaps the fix will be as simple as setting - https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/fill-rule - to evenodd, rather than nonzero (the default)? but I havent looked at the code. oh it looks like you're tesselating to triangles. that makes the fix trickier. :(

understood! I went and looked after I left my comment and saw that you're tesselating the polygons yourself. awesome, but yeah, makes it tricker. I guess you need a good javascript tesselator with support for self intersecting polygons + odd/even rules? ironically old old gl used to have a one liner more or less to do this (GLUtessellator) but I dont think GLU made it into the webgl age :) however, I can vouch for this guy being amazing so its exciting that this exists: https://github.com/memononen/tess2.js/
