Can someone clarify for me – Nurbs in C4D

[Simon Carlson-thies]

Cinema has primatives which is what you create initally, when you make the object editable it becomes a polygon object, and when you place it in a HyperNURBS object it becomes a nurbs smoothed object.

The fully nurbs objects are those like loft, and lathe… objects based on splines…

Thanks. But what are those primitives? Nurbs or Polygons? Or are they nothing (Which I don’t understand)?

Thanks again!

3d Primitives are parametric objects,
meaning created from a set of parameters,
they are neither Nurbs or Polygonal objects.

When you convert them to editable objects, you then get polygonal meshes.
C4d does not support Nurbs modelling ( as in Rhino or similar…).
The so-called nurbs objects are not really ‘Nurbs’ as understood in other programms.

as far as HyperNurbs, it is actually C4d’s implementation of Subdivision Surface modelling – so a polygon based technique as well.

Hi!

All primitives are parametric objects and are created from mathematical formulae. When they’re in this “state” they’re simply mathematical abstractions of objects and therefore not editable. However once made editable, they serve a good staring points from which to start / continue modelling from. I know this may sound confusing but after a while it will make sense.

In fact, There’s a detailed (much better) description on page 169 in the C4D manual which you can download directly from Maxons site or by clicking on the following link:

By the way Keep up your brilliant work on the Creative Cow After Effects video tutorials. I’ve learned a lot by watching them. Thanks & Respect!

True, but all objects in cinema editable or not are mathematical abstractions… what defines the primitives is that they are parametric objects… and hyperNurbs uses the principles of NURBS surfaces to smooth objects, so one can say they are a form of NURBS modeling, just not quite the same as Loft, Lathe…

Ah well, it’s always good to have a pardigm shift every once in a while… Keeps you on your toes.

Thanks for your help everyone!
