Name

glMatrixMode — specify which matrix is the current matrix

C Specification

void glMatrixMode (GLenum mode );

Python Specification

glMatrixMode ( mode ) →  None

Parameters

mode
Specifies which matrix stack is the target for subsequent matrix operations. Three values are accepted: GL_MODELVIEW, GL_PROJECTION, and GL_TEXTURE. The initial value is GL_MODELVIEW. Additionally, if the GL_ARB_imaging extension is supported, GL_COLOR is also accepted.

Description

glMatrixMode sets the current matrix mode. mode can assume one of four values:

GL_MODELVIEW
Applies subsequent matrix operations to the modelview matrix stack.
GL_PROJECTION
Applies subsequent matrix operations to the projection matrix stack.
GL_TEXTURE
Applies subsequent matrix operations to the texture matrix stack.
GL_COLOR
Applies subsequent matrix operations to the color matrix stack.

To find out which matrix stack is currently the target of all matrix operations, call glGet with argument GL_MATRIX_MODE. The initial value is GL_MODELVIEW.

Errors

GL_INVALID_ENUM is generated if mode is not an accepted value.

GL_INVALID_OPERATION is generated if glMatrixMode is executed between the execution of glBegin and the corresponding execution of glEnd.

Associated Gets
