'''S3 Texture Compression''' ('''S3TC''') (sometimes also called '''DXTn''' or '''DXTC''') is a group of related [[lossy compression|lossy]] [[texture compression]] [[algorithm]]s originally developed by Iourcha et al. of [[S3 Graphics|S3 Graphics, Ltd.]]<ref>{{patent|US|5956431|"Fixed-rate block-based image compression with inferred pixel values"}}</ref> for use in their [[Savage 3D]] computer graphics accelerator.

Unlike some image compression algorithms (e.g. [[JPEG]]), S3TC's fixed-rate data compression coupled with the single memory access (cf.

Its subsequent inclusion in [[Microsoft]]'s [[DirectX]] 6.0 and [[OpenGL]] 1.3 (via the GL_EXT_texture_compression_s3tc [[OpenGL#Extensions|extension]]) led to widespread adoption of the technology among hardware and software makers. While S3 Graphics is no longer a competitor in the graphics accelerator market, license fees are still levied and collected for the use of S3TC technology, for example in [[game console]]s and graphics cards. The wide use of S3TC has led to a [[de facto]] requirement for OpenGL drivers to support it, but the patent-encumbered status of S3TC presents a major obstacle to [[open source]] implementations.<ref>{{cite web|url=http://dri.freedesktop.org/wiki/S3TC |title=S3TC situation on official DRI information page |publisher=Dri.freedesktop.org |date= |accessdate=2012-01-25}}</ref>

There are five variations of the S3TC algorithm (named '''DXT1''' through '''DXT5''', referring to the [[FourCC]] code assigned by Microsoft to each format), each designed for specific types of image data. All convert a 4×4 block of pixels to a 64-[[bit]] or 128-bit quantity, resulting in compression ratios of 6:1 with 24-bit [[RGB color space|RGB]] input data or 4:1 with 32-bit [[RGBA color space|RGBA]] input data. S3TC is a [[lossy data compression|lossy]] compression algorithm, resulting in image quality degradation, an effect which is minimized by the ability to increase texture resolutions while maintaining the same memory requirements. Hand-drawn cartoon-like images do not compress well, nor do [[normal mapping|normal map]] data, both of which usually generate [[Compression artifacts|artifacts]]. [[ATI Technologies|ATI]]'s [[3Dc]] compression algorithm is a modification of DXT5 designed to overcome S3TC's shortcomings with regard to normal maps. [[id Software]] worked around the normalmap compression issues in [[Doom 3]] by moving the red component into the alpha channel before compression and moving it back during rendering in the [[pixel shader]].<ref>{{cite web|url=http://www.gamershell.com/news/14362.html |title=DOOM 3 Video Requirements |publisher=Gamershell.com |date= |accessdate=2012-01-25}}</ref>
 
Like many modern image compression algorithms, S3TC only specifies the method used to decompress images, allowing implementers to design the compression algorithm to suit their specific needs, although the patent still covers compression algorithms. The nVidia GeForce 1 through to GeForce 4 cards also used 16-bit interpolation to render DXT1 textures, which resulted in banding when unpacking textures with color gradients. Again, this created an unfavorable impression of texture compression, not related to the fundamentals of the codec itself.

DXT1 (also known as Block Compression 1 or BC1) is the smallest variation of S3TC, storing 16 input pixels in 64 bits of output, consisting of two 16-bit RGB 5:6:5 color values <math>c_0</math> and <math>c_1</math>, and a 4x4 two bit lookup table.
 
If <math>c_0 > c_1</math>, then two other colors are calculated, such that <math>c_2 = {2 \over 3} c_0 + {1 \over 3} c_1</math> and <math>c_3 = {1 \over 3} c_0 + {2 \over 3} c_1</math>.

The lookup table is then consulted to determine the color value for each pixel, with a value of 0 corresponding to <math>c_0</math> and a value of 3 corresponding to <math>c_3</math>. DXT1 does not store alpha data enabling higher compression ratios.

If <math>\alpha_0 > \alpha_1</math>, then six other alpha values are calculated, such that <math>\alpha_2 = {{6\alpha_0 + 1\alpha_1} \over 7}</math>, <math>\alpha_3 = {{5\alpha_0 + 2\alpha_1} \over 7}</math>, <math>\alpha_4 = {{4\alpha_0 + 3\alpha_1} \over 7}</math>, <math>\alpha_5 = {{3\alpha_0 + 4\alpha_1} \over 7}</math>, <math>\alpha_6 = {{2\alpha_0 + 5\alpha_1} \over 7}</math>, and <math>\alpha_7 = {{1\alpha_0 + 6\alpha_1} \over 7}</math>.
 
Otherwise, if <math>\alpha_0 \le \alpha_1</math>, four other alpha values are calculated such that <math>\alpha_2 = {{4\alpha_0 + 1\alpha_1} \over 5}</math>, <math>\alpha_3 = {{3\alpha_0 + 2\alpha_1} \over 5}</math>, <math>\alpha_4 = {{2\alpha_0 + 3\alpha_1} \over 5}</math>, and <math>\alpha_5 = {{1\alpha_0 + 4\alpha_1} \over 5}</math> with <math>\alpha_6 = 0</math> and <math>\alpha_7 = 255</math>.
 
The lookup table is then consulted to determine the alpha value for each pixel, with a value of 0 corresponding to <math>\alpha_0</math> and a value of 7 corresponding to <math>\alpha_7</math>. DXT4's color data is premultiplied by alpha, whereas DXT5's is not. Because DXT4/5 use an interpolated alpha scheme, they generally produce superior results for alpha (transparency) gradients than DXT2/3.

S3 Texture Compression (S3TC) (sometimes also called DXTn or DXTC) is a group of related lossy texture compression algorithms originally developed by Iourcha et al. of S3 Graphics, Ltd.[1] for use in their Savage 3D computer graphics accelerator. The method of compression is strikingly similar to the previously published Color Cell Compression,[2] which is in turn an adaptation of Block Truncation Coding published in the late 1970s. Unlike some image compression algorithms (e.g. JPEG), S3TC's fixed-rate data compression coupled with the single memory access (cf. Color Cell Compression and some VQ-based schemes) made it well-suited for use in compressing textures in hardware-accelerated 3D computer graphics. Its subsequent inclusion in Microsoft's DirectX 6.0 and OpenGL 1.3 (via the GL_EXT_texture_compression_s3tc extension) led to widespread adoption of the technology among hardware and software makers. While S3 Graphics is no longer a competitor in the graphics accelerator market, license fees are still levied and collected for the use of S3TC technology, for example in game consoles and graphics cards. The wide use of S3TC has led to a de facto requirement for OpenGL drivers to support it, but the patent-encumbered status of S3TC presents a major obstacle to open source implementations.[3]

Codecs

There are five variations of the S3TC algorithm (named DXT1 through DXT5, referring to the FourCC code assigned by Microsoft to each format), each designed for specific types of image data. All convert a 4×4 block of pixels to a 64-bit or 128-bit quantity, resulting in compression ratios of 6:1 with 24-bit RGB input data or 4:1 with 32-bit RGBA input data. S3TC is a lossy compression algorithm, resulting in image quality degradation, an effect which is minimized by the ability to increase texture resolutions while maintaining the same memory requirements. Hand-drawn cartoon-like images do not compress well, nor do normal map data, both of which usually generate artifacts. ATI's 3Dc compression algorithm is a modification of DXT5 designed to overcome S3TC's shortcomings with regard to normal maps. id Software worked around the normalmap compression issues in Doom 3 by moving the red component into the alpha channel before compression and moving it back during rendering in the pixel shader.[4]

Like many modern image compression algorithms, S3TC only specifies the method used to decompress images, allowing implementers to design the compression algorithm to suit their specific needs, although the patent still covers compression algorithms. The nVidia GeForce 1 through to GeForce 4 cards also used 16-bit interpolation to render DXT1 textures, which resulted in banding when unpacking textures with color gradients. Again, this created an unfavorable impression of texture compression, not related to the fundamentals of the codec itself.

DXT1

DXT1 (also known as Block Compression 1 or BC1) is the smallest variation of S3TC, storing 16 input pixels in 64 bits of output, consisting of two 16-bit RGB 5:6:5 color values c0 and c1, and a 4x4 two bit lookup table.

If c0>c1, then two other colors are calculated, such that c2=23c0+13c1 and c3=13c0+23c1. This mode operates similarly to mode 0xC0 of the original Apple Video codec.[5]

Otherwise, if c0≤c1, then c2=12c0+12c1 and c3 is transparent black corresponding to a premultiplied alpha format.

The lookup table is then consulted to determine the color value for each pixel, with a value of 0 corresponding to c0 and a value of 3 corresponding to c3. DXT1 does not store alpha data enabling higher compression ratios.

DXT4 and DXT5

DXT4 and DXT5 (collectively also known as Block Compression 3 or BC3) converts 16 input pixels into 128 bits of output, consisting of 64 bits of alpha channel data (two 8 bit alpha values and a 4x4 3 bit lookup table) followed by 64 bits of color data (encoded the same way as DXT1).

If α0>α1, then six other alpha values are calculated, such that α2=6α0+1α17, α3=5α0+2α17, α4=4α0+3α17, α5=3α0+4α17, α6=2α0+5α17, and α7=1α0+6α17.

Otherwise, if α0≤α1, four other alpha values are calculated such that α2=4α0+1α15, α3=3α0+2α15, α4=2α0+3α15, and α5=1α0+4α15 with α6=0 and α7=255.

The lookup table is then consulted to determine the alpha value for each pixel, with a value of 0 corresponding to α0 and a value of 7 corresponding to α7. DXT4's color data is premultiplied by alpha, whereas DXT5's is not. Because DXT4/5 use an interpolated alpha scheme, they generally produce superior results for alpha (transparency) gradients than DXT2/3.
