[Verse-dev] The Common Denominator is NURBS

[eskil at obsession.se]

Hi

Ive had this discussion a few times but i must say that i hav few  
times head it this educated. Yes NURBS do have benefits but to call it  
"The Common Denominator" of computer graphics would be wrong. Very few  
applications can handle NURBS well, and few people know tha math. The  
two major NURBS apps I know of (ALIAS studio, Rhino) was actiualy  
written by the same people.

Yes NURBS have some nice featiures, but try expressing something as  
simple as a Tetrahedron and you are in trouble. Polygons are the  
common denominator (almost all NURBS renderings first convert the  
NURBS to polygons), but they do have some limitations by not beeing  
curved. So SDS works very nicely as a "Polygions+" by adding this  
without changeing the basic and very simple data structure. I find it  
a huge feature of SDS that it is compatible with polygons.

An other thing to note is that ive gotten lots of arguments saying:  
"Verse should have NURBS", but never: "Verse should have NURBS,  
because im implementing verse support in an app that has NURBS."  ;-)

Cheers
