glMultMatrix(3G)	       OpenGL Reference		      glMultMatrix(3G)



NAME
     glMultMatrixd, glMultMatrixf - multiply the current matrix	by an
     arbitrary matrix


C SPECIFICATION
     void glMultMatrixd( const GLdouble	*m )
     void glMultMatrixf( const GLfloat *m )


PARAMETERS
     m	Specifies a pointer a to 4x4 matrix stored in column-major order as
	sixteen	consecutive values.


DESCRIPTION
     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 o T.

     The current matrix	is the projection matrix, modelview matrix, texture
     matrix, or	color matrix (if the SGI_color_matrix extension	is supported),
     as	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|
				(		 )

ERRORS
     GL_INVALID_OPERATION is generated if glMultMatrix is executed between the
     execution of glBegin and the corresponding	execution of glEnd.
