Abstract
A computer graphics apparatus is constructed for presenting on a display device a motion of an object defined by a plurality of articular segments manipulatable according to state values thereof. In the computer graphics apparatus, an input device has a plurality of control units, each of which is operable for time-sequentially inputting a control amount. An assignment device provides assignment information which defines correspondence between the control units of the input device and the articular segments of the object. A function device provides a functional parameter which defines a relation between the control amount of each control unit and the state value of each articular segment when the correspondence is defined between each control unit and each articular segment according to the assignment information. The function device further operates based on the functional parameter for converting the control amount time-sequentially inputted by each control unit into a time-series of the state value of each articular segment. A graphic device graphically manipulates each articular segment according to the time-series of the state value to present the motion of the object on the d…
