GLMATRIXMODE() MachTen Programmer’s Manual GLMATRIXMODE()

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 sub-
sequent 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 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.

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 exe-
cuted between the execution of glBegin and the correspond-
ing execution of glEnd.

ASSOCIATED GETS
