Signature

gluUnProject4( GLdouble ( winX ) , GLdouble ( winY ) , GLdouble ( winZ ) , GLdouble ( clipW ) , const GLdouble * ( model ) , const GLdouble * ( proj ) , const GLint * ( view ) , GLdouble ( nearVal ) , GLdouble ( farVal ) , GLdouble* ( objX ) , GLdouble* ( objY ) , GLdouble* ( objZ ) , GLdouble* ( objW ) )-> GLint

gluUnProject( winX , winY , winZ , model , proj , view , objX , objY , objZ ) -> <class 'ctypes.c_int'>

Convenience wrapper for gluUnProject
    
    Automatically fills in the model, projection and viewing matrices
    if not provided.
    
    returns (objX,objY,objZ) doubles

Parameters

Variables	Description
winX, winY, winZ	Specify the window coordinates to be mapped.
clipW	Specify the clip w coordinate to be mapped.
model	Specifies the modelview matrix (as from a glGetDoublev call).
proj	Specifies the projection matrix (as from a glGetDoublev call).
view	Specifies the viewport (as from a glGetIntegerv call).
nearVal, farVal	Specifies the near and far planes (as from a glGetDoublev call).
objX, objY, objZ, objW	Returns the computed object coordinates.
