WebGL - How to use Culling
In this episode, I discuss how to use back-face culling in WebGL and discuss why it's useful.
- Back-face Culling
- Determine whether a polygon is front or back facing. Meaning, triangle drawn clockwise or counterclockwise.
- If culling back-facing polygons (drawn counterclockwise), then it's facing away, and will not drawn.
- Makes rendering faster.
