glMatrixMode.3G - Man Page
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.
Associated Gets
glGet with argument GL_MATRIX_MODE
