The polygons are like building blocks. If I do not show the polygon outline, I can see that I am getting some unwanted stippling effect underneath where the edges of two polygons meet.
Does anyone have any idea what it is that I’m seeing and how it might be remedied.
Rasterization in 3D graphics is generally only stitch free when polygon edges share the exact same coordinates.
You will experience this with T-vertices, that is polygons where one long edge is aligned to two smaller ones like this
where poly 1 has an edge from v0 to v1 and polys 2 and 3 share the same vertices v0 and v1 but have the edge split at v2.
This is not going to end up without stitches!Different OpenGL implementations may show varying degrees of stitches, the more subpixel precision the rasterizer uses the better. But in general, avoid T-vertices!
