GLSCALE(3G)							   OpenGL Manual						       GLSCALE(3G)

NAME
       glScale - 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
       glMultMatrix() 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().
