Terminology

• NURBS- non uniform rational b-splines.  A modeling type where surfaces are defined by interpolated splines.  Nurbs surfaces are defined by control points
• Control Points- Specific points on a NURBS object that allow for further editability.  The object is interpolated between these points, creating a smooth transition in surface.  
• Polygon- Polygonal Modeling is defined by vertex, edges, and faces.  edges are poly-lines meaning there is no interpolation in surface
• Cage (splines)- Effectively the control points of a spline.  Allow for further editability.  The spline is interpolated between the points of the cage.
• Extrusion - Transforms an object into the next dimension of a 3d model.  ie. a line to a surface.  A surface to a solid.  The process extends the current state of the object in one linear direction to define the next state.
• Boolean - refers to the process of combining two or more objects to create a single object.
• Boolean Union - the addition of one solid object to another.  The resulting singular object is a combination of the two.
• Boolean Difference - The subtraction of one solid object from another.
• Boolean Intersection - An operation where the overlap of two solid objects is isolated and extracted.
