GLOADMATRIX(3G)                                              GLOADMATRIX(3G)



NAME
       glLoadatrixd,,  glLoadatrixf  -  replace  the  current matrix with the
       specified matrix


C SPECIFICATION
       void glLoadatrixd( const GLdouble *m )
       void glLoadatrixf( 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
       glLoadatrix  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 glatrixode).

       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 implementation may store or operate on  these  values
       in less than single precision.

ERORS
       GLINVALIDOPERATION  is  generated if glLoadatrix is executed between
       the execution of glBegin and the corresponding execution of glEnd.
