摘要： 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.

摘要： 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. An image synthesis unit mixes luminance values of a portion of the curve from an input pre-set position (tip) to the distal end of the hair (t=1) with luminance values of the background supplied from a frame buffer in a pre-set mixing ratio. An end setting unit sets the pre-set position (tip).
