GLMATRIXMODE(3G) OpenGL Manual GLMATRIXMODE(3G)
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 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
