Class Primitives

java.lang.Object
  extended by com.threed.jpct.Primitives

public class Primitives
extends java.lang.Object

Primitives offers some (lathe) primitives (basic 3D-objects). This class allows one to generate some objects for testing or other purposes quick and easy. No object editing or loading is needed. The number of faces the methods are asking for (or using the defaults) is not exactly the number of triangles the calculated object will have but rather the number of faces of the base object from which it has been constructed. But in lack of a better word, it's called "faces" here.
Except for the plane, objects created by this class don't have proper texture coordinates.
If you want proper texture coordinates for your primitives, have a look at the ExtendedPrimitives class in the util-package.
