Abstract: An animation image generating program is provided which allows animation images to be readily generated by CG without complicated setups, and more particularly the animation image generating program is suited to generate a plurality of types of face animation images by CG. The animation image generating program includes the steps of controlling selection of specific vertices of a standard model and a user model, providing control such that first target vertices are associated with second target vertices where the first target vertices are the selected specific vertices of the standard model and the second target vertices are the selected specific vertices of the user model, providing control by arithmetic means such that coordinates of the first target vertices approximate to those of the second target vertices, to generate fitting information, and animating the user model based on animation data of the standard model and on the fitting information.

Abstract: A system for forming a 3D computer graphics expression model based on emotional transition, which is provided in a computer device comprising input means, storage means, control means, output means, and display means, comprising: storage means for storing the last three layers of a five-layer neural network for expanding three-dimensional emotion parameters into n-dimensional expression synthesis parameters, three-dimensional emotion parameters in emotional space corresponding to basic emotions, and shape data that serves as a source for the formation of a 3D computer graphics expression model for expression synthesis; means for deriving emotion parameters in emotional space corresponding to specific emotions; and calculation means whereby, using data for the last three layers in a five-layer neural network having a three-unit middle layer, emotion parameters, which were derived by the emotional parameter derivation means, are input to the middle layer, and expression synthesis parameters are output at the ou

Abstract: In computer graphics, the distal end of a hair being drawn is to be prevented from being lowered in massy feeling. To this end, a data storage unit stores three-dimensional coordinates of control points of a curve, and outputs these coordinate values to a curve approximating unit under control by a controller. The curve approximating unit generates a Bezier curve, using the coordinate values of the input control points, to output the generated Bezier curve to a z-coordinate comparator. The z-coordinate comparator stores the one of the coordinate values having the same x-components and y-components which is closest to a viewing point, that is, which has the maximum z-component. A reflected light intensity computing unit computes the intensity of the light reflected by the surface of the curve.
