WebDividing a concave polygon (a) into a set of triangles (b) produces triangle edges (dashed) that are interior to the original polygon. Fortunately, OpenGL provides a mechanism that allows us to eliminate selected edges from a wire-frame display.

WebJust like a graph, the center has coordinates (0,0) and the y axis is positive above the center. This seems unnatural because graphics applications usually have (0,0) in the top-left corner and (width,height) in the bottom-right corner, but it's an excellent way to simplify 3D calculations and to stay resolution independent..

But doing so results in artifacts similar to the z-fighting phenomenon, i.e., some edges seem thinner than others or even vanish, as shown below.

WebIn the linked question, the OP was looking for an algorithm which could generate a plane with only one OpenGL triangle strip. He came up with a solution that works almost perfectly: The order of the vertices for the strip is indicated by the arrows: 1-5-2-6-3-etc. The only drawback is that it also generates one unnecessary triangle on every ...
