TEXTURE MAPPING DEVICE, TEXTURE MAPPING METHOD, AND PROGRAM

摘要

Provided is a texture mapping device, comprising: a texture atlas generating unit (10) which combines a plurality of textures and generates a texture atlas (41), and generates position information (32) in the texture atlas (41) of textures to be rendered; a polygon information storage unit (330) which stores polygon information (33), in which are set vertex coordinates of polygons in an output image (42) and vertex texture coordinates corresponding to vertex coordinates in an image which is rendered by the polygons on the basis of the textures to be rendered; a pixel coordinate computing unit (22) which detects locations in the output image (42) of pixels which are painted out by the polygons, and computes pixel correspondence texture coordinates which correspond to locations of pixels in a rendered image; and a coordinate transform unit (23) which transforms the pixel correspondence texture coordinates to coordinates within a range of the texture to be rendered upon the texture atlas (41).
