Dear friend…
Is there a limit for the control point number in a nurb surface, because if the number is greater than [24][24] the surface will not be drawn.
I hope that you can help me with this, because I need it for a project.
Thanks in advance for your help.
No need for cross post, Relic has already answered you on the math forum !
You have to understand that each nurb patch don’t need more than 4*4 control points, unless you really know what you are doing, and apparently you don’t
Read this page, specially the “Order” section :
http://en.wikipedia.org/wiki/NURBS#Order
And the circle example (even if 2D, it is a good example for you) :
http://en.wikipedia.org/wiki/NURBS#Example:_a_circle
It explains that only order 3 is used, but 4 patches are needed. Control points are reused between patches to keep the circle smooth even between patches.
