Stereo model displaying method and apparatus in video game, game apparatus, and computer-readable recording medium stored with stereo model displaying program for video game

A computer-readable recording medium stored with a stereo model display program for drawing a stereo model of a video game in a cel animation tone, the stereo model constituted by a plurality of polygons in a virtual three-dimensional space:

• wherein the stereo model display program makes a computer execute:
• a first step of determining a direction of displaying the stereo model in response to an operation input;
• a second step of arranging the stereo model and a contour drawing model, having a shape including the stereo model and constituted by a plurality of polygons, in conformity with the direction determined at the first step such that a positional relationship in which the contour drawing model includes the stereo model is constituted;
• and
• a third step of drawing the stereo model in a cel animation tone by reducing a number of a brightness values previously given to the stereo model and drawing only the polygons of the contour drawing model having a surface directed in a direction reverse to the direction determined at the first step.

An apparatus for displaying a stereo model in a video game by drawing the stereo model constituted by a plurality of polygons in a virtual three-dimensional space, wherein said apparatus executes:

• determining a direction of displaying the stereo model in response to an operation input;
• arranging the stereo model and a contour drawing model, having a shape including the stereo model and constituted by a plurality of polygons, in conformity with the determined direction such that a positional relationship in which the contour drawing model includes the stereo model is constituted;
• and
• drawing the stereo model in a cel animation tone by reducing a number of brightness values previously given to the stereo model and drawing only the polygons of the contour drawing model having a surface directed in a direction reverse to the determined direction.

A game apparatus for drawing a stereo model in a cel animation tone, the stereo model constituted by a plurality of polygons in a virtual three-dimensional space, said apparatus comprising:

• a computer;
• a computer-readable record medium stored with a program which the computer executes;
• wherein the program makes the computer execute:
• a determining processing of determining a direction of displaying the stereo model in response to an operation input;
• an arranging processing of arranging the stereo model and a contour drawing model, having a shape including the stereo model and constituted by a plurality of polygons, in conformity with the direction determined by the determining processing such that a positional relationship in which the contour drawing model includes the stereo model is constituted;
• and
• a drawing processing of drawing the stereo model in a cel animation tone by reducing a number of a brightness values previously given to the stereo model and drawing only the polygons of the contour drawing model having a surface directed to a direction reverse to the direction determined by the determining processing.
