Bezier's surface

[sdjnnzf]

Dear who ever this may concern:
1.what's the difference between the Bezier ordinate and Bezier abscissae?
2.Farin [Surfaces over Dirichlet tessellations] constructed a C1 interpolant by embedding Sibson’s natural neighbor coordinates in the Bernstein-Bezier surface representation of a cubic simplex.Can I use the Non-sibsonian natural neighbor coordinates instead of the Sibson’s natural neighbor coordinates to construct a C1 interpolant ?

Thank a lots!

Bad questions:
1. Use google, its took me 30 seconds to find the answer.
2. seems like a dodgy question reading about these neighbours - but isnt Qhull what you need?

Thanks for your reply!Perhaps what'I asked is very easy for you,but I am a tyro of CAGD,especialy some knowledges about Berstein-Bezier surface,would you like to give me some advice?

sdjnnzf, this is a topic you can easily find out more about by searching the web and reading more papers (you seem to have already read a few).
