glMatrixMode — specify which matrix is the current matrix
void glMatrixMode( | GLenum | mode); |
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 ARB_imaging extension is supported,
GL_COLOR is also accepted.
glMatrixMode sets the current matrix mode.
mode can assume one of four values:
GL_MODELVIEWApplies subsequent matrix operations to the modelview matrix stack.
GL_PROJECTIONApplies subsequent matrix operations to the projection matrix stack.
GL_TEXTUREApplies subsequent matrix operations to the texture matrix stack.
GL_COLORApplies 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.
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.
