TSc Texture Compression

Texture Compression is a very important aspect of computer graphics systems. Rendering and Processsing Images requires significant memory bandwidth. Compressing Images is of very high importance as it reduces the required bandwith and helps to utilise caches better. The Result if higher speed and lower power consumption as reducing the memory tranfers required reduces power consumption.

Examples

Compressing Gradients

TSc Texture compression is particularly efficient in compressing gradients, as you can see in the following grayscale gradient examples:

Fig1. Original image A 256 Grayscale Gradient

Fig2. Compressed with DXT1 4bpp DXT1. You can see the visible banding

Fig3. Compressed with TSc 4bpp TSc compression. You can see how the gradient is much smoother
