Building a 3D Nurbs-Based Human Form
NURBS (Non Uniform Racional B-Splines) are extremely powerful and flexible when it comes to creating organic forms. This tutorial will use NURBS in their most basic form to create a human torso.Cage Modeling a 3D Nose
This is a brief tutorial on how to create a nose shape using subdivision techniques of cage modeling. We will create the entire nose based on one simple cube from which we will extrude or pull away all the flat facets to create a blocky nose.
For complex organic shapes like hands, cage modeling is a dream come true. However, it is a good idea to strategize a bit before tearing into the process. Begin by taking a sketch or photograph of the desired modeled object and “block it off.” That is, decide where the cage or polygon subdivisions should occur.Alternate 3D Models Sources
You can purchase models through a variety of venues. They can be sent to you on CD, or can be purchased per piece online. Just do a search on 3D models with your favorite search engine, and a multitude of sites appears. Besides purchasing options, model exchanges exist where folks can contribute the models that they have created and download other models that others have made.3D Terrain Modeling
Besides the chopping, adding, bending, twisting, and deforming of polygon shapes, there are also some other important ways to create very interesting shapes. Many of these have to do with modeling landscapes. Think of trying to model every mountain, hill, groundhog mound, and anthill in an extensive landscape.
