A connection between two or more computers that allows each to transfer data to and from the others.
A state of a polygon in which a line in the plane of the polygon intersects the polygon more than twice.
A three-component plane equation that defines the angular orientation, but not position, of a plane or surface.
To divide each of the components of a normal by the square root of the sum of their squares. Then, if the normal is thought of as a vector from the origin to the point (nx', ny', nx'), this vector has unit length:
- nx' = nx/factor
- ny' = ny/factor
- nz' = nz/factor
- normal vector
Non-Uniform Rational B-Spline. A common way to specify parametric curves and surfaces.
