- W1967175041 abstract "Compression in the context of texture and bump mapping brings high-performance texture mapping in the range of low- cost systems. The size for the texture memory is significantly reduced and the necessary bandwidth between the memory and texturing unit is lowered. Textures are compressed using a lossy compression method based on vector quantization. We are proposing an alternative approach to embossing textured surfaces, where bump maps are described with bitmaps and are part of the compressed texture data. The design of a texturing circuit architecture is presented, where embossing or engraving of textured surfaces is executed by dedicated decoding and filtering hardware. The circuit decompresses textures and decodes compressed bump maps to produce wrinkled textured surfaces. Applying encoding to normal vectors results in narrower data paths. Vectors are represented and handled in a compressed format defined by their vertical and horizontal angles. In order to enhance subjective image quality, an optional space-variant filter can be applied locally during the texture mapping phase to reduce the artifacts introduced by the lossy compression method." @default.
