glMatrixMode Subroutine

OpenGL 1.2 for AIX: Reference Manual

Specifies the current matrix.

OpenGL C bindings library: libGL.a

void glMatrixMode(GLenum Mode)

The glMatrixMode subroutine sets the current matrix mode. The Mode parameter can assume one of the following three values:

GL_MODELVIEW	Applies subsequent matrix operations to the model view matrix stack.
GL_PROJECTION	Applies subsequent matrix operations to the projection matrix stack.
GL_TEXTURE	Applies subsequent matrix operations to the texture matrix stack.

Mode

Specifies which matrix stack is the target for subsequent matrix operations. The following three values are accepted:

Associated gets for the glMatrixMode subroutine are as follows. (See the glGet subroutine for more information.)

glGet with argument GL_MATRIX_MODE.

GL_INVALID_ENUM	Mode is not an accepted value.
GL_INVALID_OPERATION	The glMatrixMode subroutine is called between a call to glBegin and the corresponding call to glEnd.
