GLSCALE(3G)                                                        GLSCALE(3G)



NAME
       glScaled,,  glScalef  - multiply the current matrix by a general scaling
       matrix


C SPECIFICATION
       void glScaled( GLdouble x,
                      GLdouble y,
                      GLdouble z )
       void glScalef( GLfloat x,
                      GLfloat y,
                      GLfloat z )


PARAMETERS
       x, y, z
              Specify scale factors along the x, y, and z axes,  respectively.

DESCRIPTION
       glScale  produces a nonuniform scaling along the x, y, and z axes.  The
       three parameters indicate the desired scale factor along  each  of  the
       three axes.

       The  current  matrix  (see  glatrixode)  is  multiplied by this scale
       matrix, and the product replaces the current matrix as if glScale  were
       called with the following matrix as its argument:



                                       x 0 0 0
                                       0 y 0 0
                                       0 0 z 0
                                       0 0 0 1


       If the matrix mode is either GLMODELVIEW or GLPROJECTION, all objects
       drawn after glScale is called are scaled.

       Use glPushatrix and glPopatrix to save and restore the unscaled coor-
       dinate system.

NOTES
       If  scale  factors other than 1 are applied to the modelview matrix and
       lighting is enabled, lighting  often  appears  wrong.   In  that  case,
       enable  automatic normalization of normals by calling glEnable with the
       argument GLNORMALIZE.

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