class BezierCurves from GeomFill
|
|
|
|
---Purpose: This class provides an algorithm for constructing a Bezier surface filled from
|
|
-- contiguous Bezier curves which form its boundaries.
|
|
-- The algorithm accepts two, three or four Bezier curves
|
|
-- as the boundaries of the target surface.
|
|
-- A range of filling styles - more or less rounded, more or less flat - is available.
|
|
-- A BezierCurves object provides a framework for:
|
|
-- - defining the boundaries, and the filling style of the surface
|
|
-- - implementing the construction algorithm
|
|
-- - consulting the result.
|
|
-- Warning
|
|
-- Some problems may show up with rational curves.
