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_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
.
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.
