Surfaces - Parametric Attributes

For an overview, see Primitives and Attributes.

The attributes that affect parametric surface primitives are:

 
----------------------------------------------------------------------------------------------------------------
Interior Bundle Index OC                     PEXOCCSetInteriorBundleIndex
Parametric Surface Bundle Index OC(a)
                                             PEXOCCSetParaSurfBundleIndex
     Parametric Surface Characteristics OC   PEXOCCSetParaSurfCharacteristics
      (ASF)
 
Interior Bundle Table RA                     Interior Bundle Table (LUT) and
                                                Interior Bundle Table (Renderer)
PHIGS Interior Bundle Mode RA                PHIGS Interior Bundle Mode
----------------------------------------------------------------------------------------------------------------
 

(a)

The renderer's PHIGS interior bundle mode determines whether the interior bundle index or parametric surface bundle index selects the indicated entries of the interior bundle table.

The PEXlib primitives affected by the above attributes include:
