To display an image seen from a suitable camera viewpoint, the present invention comprises a viewpoint determination sectionthat finds a position of the camera viewpoint appropriate to a control operation of determining an action of the main character (main object), which control operation is assumed to be performed by the game player; a viewpoint movement sectionthat moves the camera viewpoint from its current position to the position found by the viewpoint determination section; and an image display sectionthat displays an image of the main character seen from the camera viewpoint.

Recording medium storing three-dimensional image processing program, three-dimensional image processing program, method and device

Vertices of a polygon model Mare sorted into those on which rays are projected (visible-surface vertices M) and those on which rays are not projected (hidden-surface vertices M) based on normal vectors Vof the vertices of the polygon model Mand a light source vector V, and shadow models (shadow volumes) M, M, Mare generated by moving the hidden-surface vertices in a direction of the light source vector V. Shadow images can be easily created by applying stenciling to these shadow models.

Three-dimensional image processing method and apparatus, readable storage medium storing three-dimensional image processing program and video game system

First, positions at opposite widthwise sides where a trace is to be created are calculated. Then, the calculated positions are successively determined as vertices to generate a polygon for the trace. Subsequently, a texture suitable for the type of the slope with which a snowboard is in contact is selected. Whether or not the selected texture has been changed is then discriminated. If the selected texture has been changed, a transparent processing is applied to textures before and/or after a change and these textures are adhered to polygons before and/or after the change. Accordingly, a three-dimensional image processing apparatus can realistically and easily create a trace formed on a ground surface or a water surface as a character runs or slides.

A character in a video game space is represented realistically and the demo screen is made enjoyable for a user. A start demo display processing unit comprises a motion order assigning unit which refers to any of a plurality of motion probability setting tables based on the player selection in the player setting unit and randomly assigns, based on the probability, the order of arrangement for the motions, a motion reproduction assigning unit for assigning the reproduction of motion in this order to the image processing unit , and a motion interpolation assigning unit for assigning to the image processing unit the interpolation to the next motion close to completion of a motion. In the image processing unit , the motion image data that have been stored are selectively referenced and processing for polygon drawing is conducted based on the assignment from the motion reproduction assigning unit and the like, and a demo screen containing motions of the player which differ for each reproduction are displayed on the display device

Display method and apparatus for displaying probability controlled orders of dynamic movements

Both legs of a human figure P are each formed by two skeletons SK , SK (SK , SK ). A dynamic model is formed by a mass particle W located at a waist position A, an elastic body SP such as a spring coupling the mass particle W and a middle point B between the feet of both legs of the human figure P, and a damper DP. The positions of the skeletons SK to SK forming the legs can be dynamically obtained by calculating the waist position and further the positions of the knees using the dynamic model. Accordingly, movements of the legs can be expressed in such a manner as to give a good presence by dynamically calculating them every scene displayed as a game progresses.
