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 glMatrixMode) 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  GL_MODELVIEW  or  GL_PROJECTION,  all  objects  drawn  after
       glScale is called are scaled.

       Use glPushMatrix and glPopMatrix to save and restore the unscaled coordinate 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 GL_NORMALIZE.

ERRORS
       GL_INVALID_OPERATION  is generated if glScale is executed between the execution of glBegin
       and the corresponding execution of glEnd.

ASSOCIATED GETS

       glGet with argument GL_MODELVIEW_MATRIX
