curve and surfaces applications
B-spline, and NURB techniques
Together, Gerald and Dianne have nearly fifty years of experience
in this area.

triangulation of NURBS surfaces: Discretize (triangulate)
a NURBS surface adaptively for faster rendering and analysis
- Data format
conversions: Bezier, B-spline, Hermite, NURBS, conics, IGES,
functions: Just about any NURBS or Bezier utility function
you can think of! (evaluation, subdivision, degree elevation,
tool size detection: Analysis of surface curvatures and features
for the purpose of determining the appropriate cutting tool radius
cam: Define instructions necessary to simulate cam action
in the cutting of straight and helix fluted taps
parametric design of a turbine blade: Create a software library
to automate the turbine blade design process so that a given set
of 2D profile curves uniquely defines the 3D geometry as a C2
extension: Extend a surface linearly or with continuous curvature
edge tangency: master/slave surface smoothness correction
(position or curvature continuity)
dish positioning: Determine the azimuth angle given a satellite's
modeling: Mathematical modeling of the bracket area of teeth
for the purpose of analysis over population groups -- better braces
modeling: Mathematical modeling of a prosthetic given a scanned
body part (knee area, ankle or midfoot)
laser scanner software: NURBS modeling of surfaces scanned
by a tactile laser scanner.
lens design: Mathematical models of lenses for photorealistic
display and manufacturing
shoe software: Scanned foot data would be converted to a custom
last. We worked with some of the finest last designers to develop
a feasible in-store scanning, last creation, and shoe making technology.
