GLLOADMATRIX(3G)		 OpenGL Manual		      GLLOADMATRIX(3G)

NAME
       glLoadMatrix - 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,
       modelview 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 = m
       ⁡ 0 m ⁡ 1 ... m ⁡ 15, then the modelview transformation M ⁡ v does the
       following:

       M ⁡ v = m ⁡ 0 m ⁡ 4 m ⁡ 8 m ⁡ 12 m ⁡ 1 m ⁡ 5 m ⁡ 9 m ⁡ 13 m ⁡ 2 m ⁡ 6 m
       ⁡ 10 m ⁡ 14 m ⁡ 3 m ⁡ 7 m ⁡ 11 m ⁡ 15 × v ⁡ 0 v ⁡ 1 v ⁡ 2 v ⁡ 3

       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().
