We have two options in triangle winding direction,
- clock-wise
- counter-clockwise
Anyway converting between them could take some cost. I want to avoid conversion as much as possible, and to do that, I need to know de facto standard of winding direction. I think there's one because many big corporations are using OpenGL, and I think if there's one direction which is used by most of them, that's de facto standard.
If there's no such thing, please let me know.
