Abstract: A multi-resolution clipping texture with INDEX-DATA structure is presented to solve the huge size problem of single-resolution clipping texture data. Firstly, definition and structure of multi-resolution clipping texture are introduced; then multi-resolution clipping texture’s construction method and volume clipping technology based on multi-resolution clipping texture are discussed; finally, experiment results are discussed. The method presented in the paper has been applied in visualization software SVIP and the result is satisfactory.

Key words: computer application, INDEX-DATA texture, multi-resolution, volume clipping, direct volume rendering
