Abstract
The goal of research is to consistently build an animation system for a virtual reality system. At first let us define what animation is and what it does. A natural way supposes that virtual reality systems have characters to move and act within it. Each character is represented as a set of geometry pieces. Such pieces join hierarchically as nodes to form a clump. For a node hierarchical link is associated with a transformation matrix. Such transformation matrix represents three-dimensional space conversion for a node basing upon the node father three-dimensional space. Usually that means that the transformation matrix represents a node position and orientation relative to its father. Let us suppose that we change a single transformation matrix a bit. Because of the construction, some nodes will remain intact and some will shift to another position and/or change orientation. Those nodes that shift are the node where the matrix has been changed and all its descendants down the hierarchy. Now let us suppose that we change several transformation matrices at the same time. More movement will take place. This way we can change one character pose to another and thus create any number of character poses. Organizations of such poses forms an animation system task in terms of a virtual reality system. Maintaining organized change of transformation matrices forms an animation system task in programming terms.
