GL.TexCoord3

public static void TexCoord3(float x, float y, float z);

Description

Sets current texture coordinate (x,y,z) for all texture units.

In OpenGL this matches glMultiTexCoord for all texture units or glTexCoord when no multi-texturing is available. On other graphics APIs the same functionality is emulated.

The Z component is used only when:
1. You access a cubemap (which you access with a vector coordinate, hence x,y & z).
2. You do "projective texturing", where the X & Y coordinates are divided by Z to get the final coordinate. This would be mostly useful for water reflections and similar things.

This function can only be called between GL.Begin and GL.End functions.
