2-2. Links to Nodes in NIFF

4. Object Hierarchical Links and Animation

Animation nodes are linked from each object node in NIFF data. For instance, consider the hierarchical links of an object such as the arm illustrated below.

Figure: Three Object with a Parent/Child Relationship

In this case, the hierarchical links between the objects from Obj_0 down and animation are as illustrated below.

Figure: Object Hierarchical Links and Animation

In other words, Obj_0 is animated with Anim_0 matrix data, Obj_1 is animated as the result of multiplying the matrix data Anim_0 and Anim_1, and Obj_2 is animated by multiplying the matrix data Anim_0, Anim_1, and Anim_2.
