Name

  gluProject - map object coordinates to window	coordinates

C Specification

  int gluProject( GLdouble objx,

		  GLdouble objy,

		  GLdouble objz,

		  const	GLdouble modelMatrix[16],

		  const	GLdouble projMatrix[16],

		  const	GLint viewport[4],

		  GLdouble *winx,

		  GLdouble *winy,

		  GLdouble *winz )

Parameters

  objx,	objy, objz

		  Specify the object coordinates.



  modelMatrix	  Specifies the	current	modelview matrix (as from a

		  glGetDoublev call).



  projMatrix	  Specifies the	current	projection matrix (as from a

		  glGetDoublev call).



  viewport	  Specifies the	current	viewport (as from a glGetIntegerv

		  call).



  winx,	winy, winz

		  Return the computed window coordinates.

Description

  gluProject transforms	the specified object coordinates into window

  coordinates using modelMatrix, projMatrix, and viewport.  The	result is

  stored in winx, winy,	and winz.  A return value of GL_TRUE indicates

  success, and GL_FALSE	indicates failure.
