TEXTURE MAP FORMATION METHOD, PROGRAM FOR TEXTURE MAP FORMATION, AND TEXTURE MAP FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To enable the drawing of a 3D object while remarkably reducing the deterioration of image quality by forming a texture map for drawing the 3D object by use of 3DCG software while increasing the memory quantity of the texture map. SOLUTION: This method comprises a means for imaging the 3D object from a plurality of visual points to acquire a plurality of images; means (a projection processing part 2, an occlusion processing part 3, and a texture data mapping processing part 4) for transforming triangle data of the 3D object surface to triangle data on a two-dimensional image by use of an image with a visual point where a triangle on the 3D object surface shows the maximum area, the image being selected from the acquired images, and determining the coordinate value and texture data of a right isosceles triangle on the texture map by calculation. These texture data are mapped on each triangle on the texture space including the texture data of the peripheral area of the triangle on the two-dimensional image. COPYRIGHT: (C)2004,JPO&NCIPI
