glMultMatrixd, glMultMatrixf - multiply the current matrix by an arbitrary matrix
void glMultMatrixd( const GLdouble *m ) void glMultMatrixf( const GLfloat *m )
m Specifies a pointer a to 4x4 matrix stored in column-major order as
sixteen consecutive values.
glMultMatrix multiplies the current matrix with the one specified in m. That is, if M is the current matrix and T is the matrix passed to glMultMatrix, then M is replaced with M · T. The current matrix is the projection matrix, modelview matrix, or texture matrix, determined by the current matrix mode (see glMatrixMode). m points to a 4x4 matrix of single- or double-precision floating-point values stored in column-major order. That is, the matrix is stored as |a0 a4 a8 a12| | | |a1 a5 a9 a13| | | |a2 a6 a10 a14| | | |a3 a7 a11 a15|
GL_INVALID_OPERATION is generated if glMultMatrix is executed between the execution of glBegin and the corresponding execution of glEnd.
