- specify which matrix is the current matrix
C SPECIFICATION
PARAMETERS
_param1 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. _param1 can
assume one of four values:
GL_MODELVIEW Applies subsequent matrix opera-
tions to the modelview matrix
stack.
GL_PROJECTION Applies subsequent matrix opera-
tions to the projection matrix
stack.
GL_TEXTURE Applies subsequent matrix opera-
tions to the texture matrix
stack.
GL_COLOR Applies subsequent matrix opera-
tions 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 _param1 is not an accepted
value.
GL_INVALID_OPERATION is generated if glMatrixMode is exe-
cuted between the execution of glBegin and the correspond-
ing execution of glEnd.
