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 4x4 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) =  m[2]  m[6]  m[10] m[14]  X  v[2]
                 m[3]  m[7]  m[11] m[15]     v[3]



       Where ``X'' 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 implementa-tion implementation
       tion 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.
