NAME

glMatrixMode − specify which matrix is the current matrix
 

C SPECIFICATION

void glMatrixMode( GLenum mode )

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. 

DESCRIPTION

glMatrixMode sets the current matrix mode.  mode can assume one of three 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. 

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

glGet with argument GL_MATRIX_MODE
