Quadratic Primitives NURBS v2.0 is a package of 12 plug-ins for Autodesk 3ds Max that represent 12 primitives (curves and surfaces) powered by Spline and NURBS. They are developed for Autodesk 3ds Max.
The package includes twelve objects: three quadratic curves (which are also known as conic sections or conics) and nine quadratic surfaces.
This is the first group of plug-ins for 3ds Max on the market, which presents the full package of primitives for modeling of/with the forms mentioned above. The curves could be created as Spline and NURBS, and the surfaces as Mesh and NURBS.
After installing the package and starting 3ds Max a new group Quadratic Primitives -NURBS is appeared in Create -> Geometry.
You may create the curves as NURBS CV curves (of 3rd order) and the surfaces as NURBS CV surfaces (of 3rd or 4th order). An exact representation is presented. It is in real time. It is not an interpolation or approximation method. It is a complex mathematical representation. A NURBS model that represents exactly the given curve or surface was developed for every primitive. The NURBS curves and surfaces could be subdivided.
In the process of modeling with a NURBS quadratic curve (surface) you could modify a part or parts of it and the other part or parts preserves the form of the quadratic object with its special features.
For more information and examples you could look at the User Manual which is available for download from this page.
