The quest to build the perfect steampunk robot continues. Since we had already been introduced to polygonal modeling, we now moved on to modeling in NURBS. Nurbs stands for Non-Uniform-Rational-B-Splines, which is a fancy way for saying a non-standard curve. NURBS differ from polygons in that all surfaces have four boundaries each defined by a curve. For example, all of the tubes here on the robot are NURBS surfaces, essentially a plane wrapped around in a circle and bent along a curve.
NURBS are typically used in more organic shapes and meshes, but they have some merit when it comes to producing large surfaces.
Um. Batman came immediately to mind.
