Flash MX 2004 Games Figure 4.9 The main body for the cat model position of the points in a mesh. Lightwave can decide which points a bone modifies on the basis of location. A point will be controlled more by nearby bones than by distant bones. This method works for some meshes but can cause errors in character animation as limbs are so close together that the left thigh bone may influence the right thigh bone. Another technique is to create a definite relationship between a bone and certain points in the mesh. To set up a character to use bones in this way you create vertex maps; a vertex map is simply a list of vertices with each vertex getting a specified weight. A weight of 100 per cent means total control over the vertex while a weight of 50 per cent means partial control. In this way you can control exactly which bone adjusts which points and errors are eliminated. Animating the character Once the character is set up to use bones you have control over each part of the mesh. Another useful feature of most computer animation programs is the use of Inverse Kinematics (IK). This is just a fancy name that means that you can move the body but the feet will stay put. When animating a character, IK is a very useful feature and well worth setting up. You create a Null object (an object which is used for animating but contains no geometry so it is invisible to the camera) and this will become the target for the feet. Using IK, the feet will move to the target and can be made to rotate towards the target. The cat character uses IK on the feet, tail and eyes. 52
Figure 4.10 Animating the cat character Figure 4.11 The main keys in the cat’s walk Chapter 4: Using CGI programs to create animation Once set up correctly you can move and rock the body and the feet stay anchored, while the eye target ensures that the eyes stay locked in a direction even as the body moves. Animating the character uses the principles that have been outlined in the previous chapter. For a walk you put in the extremes, then the passing positions and finally the up and down positions. 53
