Patent ID: 7348990

Claim:
A multi-dimensional texture drawing apparatus comprising: a texture converting unit configured to rearrange a plurality of texture images forming a multi-dimensional texture image in units of particular unit areas to convert the plurality of texture images into a plurality of anisotropic textures, wherein: each of the plurality of texture images is designated by parameters of a view position and parameters of a lighting position, each of the plurality of anisotropic textures expresses an anisotropic variation of the multi-dimensional texture image in a corresponding unit area, each of the anisotropic textures includes a plurality of block images, and each of the plurality of block images is designated by the parameters of the view position and the parameters of the lighting position of the corresponding unit area; a parameter calculating unit configured to calculate view position parameters when the view position is viewed from a drawing position on a surface of a model and lighting position parameters when the lighting position is viewed from the drawing position, in accordance with a shape of the model and drawing environment; an acquiring unit configured to acquire a block image from among the plurality of block images of the plurality of anisotropic textures, the acquired block image being selected based on the parameters of the view position and the parameters of the lighting position corresponding to the calculated view position parameters and the calculated lighting position parameters; and a mapping unit configured to map the acquired block image onto the drawing position on the model.
