I trying to implement 3D map with geographic data. These data were consist of
a large number of vertices, irregularly. So I wrote drawing mode ‘glBegin(GL_POLYGON)’
and rendering scene was fine.
But when I filled these polygons for shading, it happened incorrectly result.
I show you some case…
before filling
after filling
I think OpenGL renderer designed to optimize, so it fill with winding in outline
for optimization. Is this right? If I fault, tell me good idea this problem.
How can I solve this problem?
