実際のテクスチャ unit
に現在のテクスチャ座標 (x, y, z) を設定します。
In OpenGL this matches glMultiTexCoord
for the given texture unit
if 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.
この関数は GL.Begin と GL.End 関数の間で呼び出すことができます。
