C Specification

void glMatrixMode(GLenum mode);
 

Parameters

mode

Specifies which matrix stack is the target for subsequent matrix operations. These values are accepted: GL_MODELVIEW, GL_PROJECTION, and GL_TEXTURE. The initial value is GL_MODELVIEW.

Description

GL_PROJECTION

Applies subsequent matrix operations to the projection matrix stack.

GL_TEXTURE

Applies subsequent matrix operations to the texture matrix stack.
