16.6 Clipped Class

A Clipped Object is one Object clipped by another. The first Object is actually rendered; the second represents a region to which the first Object is clipped. The clipping Object is expected to be a closed convex surface. The portion of the first Object that is within the clipping Object is rendered. If the clipping Object is not a closed convex surface, the results are undefined. The clipping is performed by the renderer during the rendering process. Thus clipping is provided as a data structure for representing the Clipped Object to the renderer, rather than as an explicit operation.

Clipped DXNewClipped()

Creates a new Clipped Object. See DXNewClipped.

Clipped DXGetClippedInfo()

Returns the Object to be rendered and the clipping Object. See DXGetClippedInfo.

Clipped DXSetClippedObjects()

Sets the Object to be rendered and the Object to clip it with during the rendering process. See DXSetClippedObjects.
