Trim curve vertex Data Type

Declaration:

ttcv ( <scalar>, <scalar>, <scalar>, <scalar> )

Literal:

tcv (<scalar>, <scalar>, <scalar>, <scalar> )

Purpose:

This defines a trim curve vertex. A trim curve vertex may be specified as a literal. All of its components are identified by position rather than by keywords. They are interpreted as

	( u, v, w, t)

where:

u and v	the parametric space coordinates of the trim curve vertex.
w	the weight of the vertex.
t	parametric distance in the space of the curve it helps describe.

Limitations:

The elements of a trim curve vertex must be literals. They may not be represented by expressions or variables.

Example:

tcv (0.007, 0.65, 1.0, 0.34 ), ...
