GL Class

Scripting > Runtime Classes > GL

Low-level graphics library.

Use this class to manipulate active transformation matrices, issue rendering commands similar to OpenGL's immediate mode and do other low-level graphics tasks. Note that in almost all cases using Graphics.DrawMesh is more efficient than using immediate mode drawing.

This class is only available in Unity Pro.

Class Variables

TRIANGLES	Mode for Begin: draw triangles.
TRIANGLE_STRIP	Mode for Begin: draw triangle strip.
QUADS	Mode for Begin: draw quads.
LINES	Mode for Begin: draw lines.
modelview	The current modelview matrix.

Class Functions
