PARAMETERS

       coord   Specifies a texture coordinate.  Must be GL_S, GL_T,  GL_R,  or
               GL_Q.

       pname   Specifies  the  symbolic  name  of the value(s) to be returned.
               Must be either GL_TEXTURE_GEN_MODE or the name of  one  of  the
               texture   generation   plane   equations:   GL_OBJECT_PLANE  or
               GL_EYE_PLANE.

       params  Returns the requested data.

DESCRIPTION

       glGetTexGen returns in params selected parameters of a texture  coordi-
       nate  generation  function  that  was  specified using glTexGen.  coord
       names one of the (s, t, r, q) texture coordinates, using  the  symbolic
       constant GL_S, GL_T, GL_R, or GL_Q.

       pname specifies one of three symbolic names:

       GL_TEXTURE_GEN_MODE         params  returns  the  single-valued texture
                                   generation function, a  symbolic  constant.
                                   The initial value is GL_EYE_LINEAR.

       GL_OBJECT_PLANE             params  returns  the  four  plane  equation
                                   coefficients that  specify  object  linear-
                                   coordinate   generation.   Integer  values,
                                   when requested, are  mapped  directly  from
                                   the internal floating-point representation.

       GL_EYE_PLANE                params  returns  the  four  plane  equation
                                   coefficients  that specify eye linear-coor-
                                   dinate generation.   Integer  values,  when
                                   requested,  are  mapped  directly  from the
                                   internal   floating-point   representation.
                                   The returned values are those maintained in
                                   eye coordinates.  They are not equal to the
                                   values specified using glTexGen, unless the
                                   modelview matrix was identity when glTexGen

       the execution of glBegin and the corresponding execution of glEnd.
