1 Compression in the Graphics Pipeline
نویسنده
چکیده
This paper explores the subject of compression in the graphics pipeline. While there are several components of the pipeline that could stand to benefit from compression, we chose to focus on the Z-buffer and the framebuffer. We describe a method of compression using pixel differencing and Huffman coding along with a caching system designed around tiles. We examine the effects of tile size, pixel differencing schemes and variations of Huffman coding on compression rates, and show the tradeoffs between these parameters.

This paper presents a decompression pipeline capable of accelerating out-of-core volume rendering of time-varying scalar data. Our pipeline is based on a twostage compression method that cooperatively uses the CPU and GPU (graphics processing unit) to transfer compressed data entirely from the storage device to the video memory. This method combines two different compression algorithms, namely ...
متن کاملLocally-Adaptive Texture Compression
Current schemes for texture compression fail to exploit spatial coherence in an adaptive manner due to the strict efficiency constraints imposed by GPU-based, fragment-level decompression. In this paper we present a texture compression framework for quasi-lossless, locally-adaptive compression of graphics data. Key elements include a Hilbert scan to maximize spatial coherence, efficient encodin...
