glLoadMatrix(3G)					      glLoadMatrix(3G)

NAME
       glLoadMatrix, glLoadMatrixd, glLoadMatrixf - replace the current matrix
       with the specified matrix

SYNOPSIS
       void glLoadMatrixd(
	       const GLdouble *m ); void glLoadMatrixf(
	       const GLfloat *m );

PARAMETERS
       Specifies a pointer to 16 consecutive values, which  are	 used  as  the
       elements of a 4 times 4 column-major matrix.

DESCRIPTION
       glLoadMatrix()  replaces the current matrix with the one whose elements
       are specified by m. The current matrix is the projection	 matrix,  mod‐
       elview  matrix, or texture matrix, depending on the current matrix mode
       (see glMatrixMode()).

       The current matrix, M, defines a	 transformation	 of  coordinates.  For
       instance, assume M refers to the modelview matrix. If  v = (v[0], v[1],
       v[2], v[3]) is the set of object coordinates of a vertex, and m	points
       to  an  array  of  16 single- or double-precision floating-point values
       m[0], m[1],. . .,m[15], then the modelview transformation M(v) does the
       following:
		 m[0] m[4]  m[8]  m[12]		v[0]

		 m[1]	  m[5]	   m[9]	    m[13]	     v[1]    M(v)    =
       times
		 m[2] m[6] m[10]  m[14]		v[2]

		 m[3] m[7] m[11]  m[15]		v[3]

       Where ``times'' denotes matrix multiplication.

       Projection and texture transformations are similarly defined.

NOTES
       While the elements of the matrix may be specified with single or double
       precision,  the	GL implementation may store or operate on these values
       in less than single precision.

ERRORS
       GL_INVALID_OPERATION is generated if glLoadMatrix() is executed between
       the execution of glBegin() and the corresponding execution of glEnd().
