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
  m   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, 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[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().
