GLLOADMATRIX(3G)					      GLLOADMATRIX(3G)

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

C SPECIFICATION
       void glLoadMatrixd( const GLdouble *m )
       void glLoadMatrixf( const GLfloat *m )

PARAMETERS
       m  Specifies a pointer to 16 consecutive values, which are used as  the
	  elements of a 4×4 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)=⎝			    ⎠×⎝	   ⎠

			       m[2] m[6] m[10] m[14]   v[2]

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

       Where ``×'' 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.
