Overview
ThreeDHacks is an interface providing additional surface types to ThreeDWorld. Currently, it adds two types: $FatPoint, an exaggerated point in 3-space, and $FatSeg, a piecewise-linear arc in 3-space.

CADTypes USING [VertexSequence, TriangleSequence],
Rope USING [ROPE],
ThreeDBasics USING [Context, ShapeInstance],
Geometry3dVector USING [Triple, TripleSequence];

DEFINITIONS ~
BEGIN
RegisterNewClasses:
PROC [context3d:
REF ThreeDBasics.Context];
Registers the $FatPoint and $FatSeg surface classes in the 3d context.
MakeFatPoint:
PROC [name: Rope.
ROPE, position: Geometry3dVector.Triple]
RETURNS [newFatPoint:
REF ThreeDBasics.ShapeInstance];
Returns a new FatPoint described by name and position.
MakeFatSeg:
PROC [name: Rope.
ROPE, points: Geometry3dVector.TripleSequence]
RETURNS [newFatSeg:
REF ThreeDBasics.ShapeInstance];
Returns a new FatSeg described by name and points.
MakeTwoCell: PROC [name: Rope.ROPE, vertices: REF CADTypes.VertexSequence, triangles: REF CADTypes.TriangleSequence] RETURNS [newTwoCell: REF ThreeDBasics.ShapeInstance];
END.
