TexCoords(TRIANGLE?

Cel · 2000-08-18T10:41:06

Hey, I have a potentially dumb question: All these tutes I have found show how to assign texture co ordinates to GL_QUADS. This is fine because 4 vertices and 4 texture co ordinates (one for each texture corner). HOWEVER, I am currently slightly baffled at how to apply tex co ords to a triangle correctly! TRIANGLE = 3 vertices, 2d texture = 4 co ords....?? Please someone shed some light on applying textures to triangles as opposed to quads or have I just missed something really obvious?? Thnx heaps, Cel
