The creation and manipulation of curved solid objects with piecewise algebraic surfaces in implicit and parametric form.
The SHILP solid modeling and display toolkit for the interactive creation and manipulation of curved solid objects with piecewise algebraic surfaces in implicit and parametric form.
SHILP is a boundary representation based solid modeling system. The boundary representation data structure of SHILP solid models allows curve and surface patches to be represented either implicitly or in rational parametric form with either power Bernstein-Bezier polynomial bases. The current functionality of the toolkit includes extrude, revolve and offset operations, edit operations on laminas and solids, pattern matching and replacement, boolean set operations, fleshing of wireframes with smooth algebraic surface patches, blending and rounding of solid corners and edges, and shaded display of solids.
Version 1 of SHILP is available from anonymous FTP at ftp.cs.purdue.edu in the file /pub/shastra/shilp-sun.tar.Z
