vpGetMaterial(3) Library Functions Manual vpGetMaterial(3) 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 argu- ments are exactly analogous to vpSetMaterial except that the surface_side argument may not be VP_BOTH_SIDES, and the final three arguments are point- ers 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. SEE ALSO VolPack(3), vpCreateContext(3), vpSetMaterial(3) VolPack vpGetMaterial(3)
