Tutorials
Behaviors
Sex and Violence animates a scene using behaviors placed upon individual models. Some models are given the ability to reproduce while others are given the ability to "eat" models they approach.
Baby Spheres uses behaviors to cause 2 spheres to reproduce when they collide. The babies inherit their parents behavior and can reproduce themselves, so this scene can be different upon each subsequent replay. The parameters controlling the animation of offspring are set using a graphical control. This example uses SoftWish's bounding-box based collision detector.

Behaviors can calculate position information and write it to files or to other devices, it's a lot easier than writing a channel driver too. This tutorial calculates the angle of a joint and displays it continuously. |
 |
Here's an easy way to convert from behavior based animation to fcurves. In this example we animate a ball, making it bounce and change size using behaviors, while saving these behavior-induced transformations as fcurves. |
Zillions Of Similar Expressions? No Problem!
 |
There are times when one needs to build many similar expressions. We can use the names that SoftimageŽ assigns to elements and TCL's excellent string handling to make such situations relatively painless. As an example, we build a Venetian blind and use programmatically generated expressions, both to position the slats of the Venetian blind relative to each other and to build a control so that we can adjust the rotation of all the slats simultaneously. |

Another example of modeling using programmatically generated expressions. In this example we build a strip of film and use programmatically generated expressions to "punch" the sprocket holes, then map the sequence of images onto the frames of film. |
