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.
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.
