3D Character Modeling With Patches.
Before NURBS (Non Rational Uniform B-Splines) modeling was available within MAX, the only way to get smooth, complex surfaces without too much polygonal detail was via the Patch surface. Patches come from a similar background as NURBS and they By using the Blend surface, you can create a smooth and flexible transition surface between the upper arm and forearm. The end result is something that animates very well-and you do not have to worry about it staying connected.
Two arm segments represent an ideal candidate for using the Blend surface. Not only are they separate surfaces, but they can also help "shape" the Blend surface through their own contours. For example, it deforms as necessary to remain connected to the two arm components. Mixed surfaces can be used in other ways as well, such as if you wanted to connect the arm to the torso. Blends also work very well when you want to connect fingers to a palm. Simply trim away the areas on the palm and fingers that you want to eliminate and then connect them using the Blend command (Free 3d model).
As with any dependent surface, both Blend and Ruled surfaces can be made independent. This disassociates the Mixed or Ruled surface from the other two surfaces or curves that originally created it. behave much like a curves surface. NURBS surfaces have evolved in your 3D Application, however, to be much more complex than patches. Patches cannot be lofted, trimmed, or constructed from cross-sections.
Instead, patches, as their name implies, are built-in sections that connect together to produce a smooth surface. Patches do require a somewhat different modeling thought process. Building patches can be done in one of two ways: through Patch surfaces or primitives. Primitives give you the ability to start with a more complex shape from which to build. For instance, building an arm from a patch cylinder is much easier than building from a series of Quad Patch objects and free 3d model.
