Embodiment Construction

[0021] Hereinafter, best embodiments of the present invention will be described in detail with reference to the drawings.

[0022] In this embodiment, a virtual three-dimensional space is established on the memory of the computer. In this virtual three-dimensional space, a three-dimensional model (three-dimensional object) composed of one or more (in this embodiment, a plurality of) polygons is arranged. FIG. 1 is a perspective view showing the shape of the three-dimensional model at a certain time (here, t=0000 is assumed). The three-dimensional model shown in this figure has a shape in which four quadrangular prisms of approximately the same size overlap each other, and each quadrangular prism is defined by 8 vertices and constituted by 6 polygons. In addition, in the 3D model, two skeletons (bones) A ​​and B are set, and the posture of the upper two square columns changes according to the skeleton A, while the posture of the lower two square columns changes according to th...

Abstract

To provide an image processing device, an image processing method, and an information storage medium for achieving preferable texture mapping onto a three dimensional model which moves in a virtual three dimensional space. The image processing device (10) for mapping, on each of one or more polygons forming a three dimensional model placed in a virtual three dimensional space, a texture specified by texture coordinates of the polygon and displaying the three dimensional model, comprises a three dimensional model posture changing unit (14a) for changing a posture of the three dimensional model as time passes according to predetermined motion data (18), and a texture coordinate shifting unit (14b) for shifting texture coordinates of the polygon according to change of the posture of the three dimensional model as time passes, which is caused by the three dimensional model posture changing unit (14a).

Description

technical field [0001] The present invention relates to an image processing device, an image processing method, and an information storage medium, and particularly relates to an image processing device, an image processing method, and an information storage medium that display a three-dimensional model arranged in a virtual three-dimensional space using texture mapping. Background technique [0002] The technology of so-called 3DCG (3 Dimensional Computer Graphics, 3D computer graphics) that creates a virtual 3D space on a computer memory, arranges a 3D model composed of multiple polygons in the space, and displays it on a monitor is quite popular. In 3DCG, generally, an image (texture) is mapped to each polygon by a method called texture mapping. In texture mapping, for example, for the 3D model with a positive appearance as shown in Figure 8(a), the original image containing multiple textures as shown in Figure (b) is prepared in advance, and each polygon ( polygon) (indi...
