NAME

       vpGetMaterial - get material properties

SYNOPSIS

       #include <volpack.h>

       vpResult
       vpGetMaterial(vpc, material, property, surface_side, r_ptr, g_ptr, b_ptr)
           vpContext *vpc;
           int material;
           int property;
           int surface_side;
           double *r_ptr, *g_ptr, *b_ptr;

ARGUMENTS

       vpc    VolPack context from vpCreateContext.

       material
              A  constant  specifying  a  particular material number (VP_MATERIAL0, VP_MATERIAL1,
              ..., VP_MATERIAL5).

       property
              A constant specifying one material property (VP_AMBIENT, VP_DIFFUSE, VP_SPECULAR or
              VP_SHINYNESS).

       surface_side
              A   constant   specifying   one  side  of  the  material  surface  (VP_EXTERIOR  or
              VP_INTERIOR).

       r_ptr, g_ptr, b_ptr
              Locations to store the RGB components of the color associated  with  the  property.
              For VP_SHINYNESS, g_ptr and b_ptr are not used.

DESCRIPTION

       vpGetMaterial is used to get the properties of a material type.  The arguments are exactly
       analogous to vpSetMaterial except that the surface_side argument may not be VP_BOTH_SIDES,
       and  the  final  three  arguments  are  pointers  to  locations  for  storing the material
       properties.

ERRORS

       The normal return value is VP_OK.  The following error return values are possible:

       VPERROR_BAD_VALUE
              The material number is invalid.

       VPERROR_BAD_OPTION
              Either the surface_side or property arguments are invalid.
