Superclass

• <DRM SEDRIS Abstract Base>

Subclass

Constraints

• Image mapping functions and texture coordinates
• Publishable object

Example(s)

• Consider a <DRM Polygon> instance P for which the data provider wishes to supply a texture coordinate at the centre of P rather than at one of its vertices To achieve this, the data provider supplies a <DRM Tack Point> component K for P such that K specifies the centre of P as its <DRM Location> component and the desired texture coordinate as a <DRM Texture Coordinate> component.
