Chapter 10. Characters > Additional Criteria

Additional Criteria

As noted earlier, the functional requirements for our models of Spot and The Jerk are that they smoothly transition downstream to animation and rendering. We can ensure this in several ways, as the following sections illustrate.

Level of Detail

The two character models must be bound to a skeletal structure, to accommodate enough detail at the joints. To do this, we need to make sure at subdiv levels 0 or 1 that there are enough vertices to bind to the skeleton when it is rigged. During the modeling process, great care must be taken to make sure that the model's surface flow lines are even and ordered. The best way to do this is to build the models first as polygonal boxes and then convert them into subdivs later. You also should test the conversion at various steps to make sure that the model is not going down the wrong path. To ensure that Erick Miller had a good enough model to rig for animation I consulted with him early on for what he needed. His biggest requirement was for most of the detail to be at subdiv Level 0. The original polygon model's vertices correspond exactly to the Level 0 points.
