Modeling the Body
The head of this model required strict adherence to digitized reference because it had to match a puppet exactly from shot to shot. The body had to be modeled differently from the puppet to accommodate animation requirements, and the body did not have to look exactly like the puppet because the body of the puppet was not shown very often in the movie. Rhythm & Hues was commissioned to do the character because the film needed a digital version of Dino for shots that showed the body. Therefore, a more natural approach to modeling the body was taken. The steps that were used to model the body are similar to the steps used to model the head, but an important difference is the way the model was started. The digitized reference was used in a much looser way for the body than the head, as outlined in the following steps.
2. Instead of copying and rebuilding curves from digitized data, rough NURBS primitives were used to approximate the position and layout of the reference data (Figure 23). NURBS sculpting of the primitive as a free-form shape was used to get the shapes of the legs and body. The transitions between the body and legs were also roughed-in. Using this technique, the NURBS primitives became the initial surfaces in the patch modeling process.
4. The surfaces were modified to get the isoparms to flow in the same direction. The majority of the work was done on the body to get the flow of the isoparms to go around the shoulders and hips of the character (Figure 25).
