FXT1: Texture Compression What is it?FXT1: Texture Compression What is it?

— Next-generation advanced texture compression technology

— Open source

— Encoding and decoding tools and source code for compression of textures for 3D objects

— Free

t e c h n o l o g yi n n o v a t i o n

FXT1: Texture CompressionSolving the problems of limited storage and bandwidth available for texturing

FXT1: Texture CompressionSolving the problems of limited storage and bandwidth available for texturing

— Storage: Reduces the amount of memory required to store a given texture up to 8:1 Higher resolution textures can now be utilized

— Bandwidth: Reduces the amount of memory bandwidth required for texturing Dramatic fill-rate performance can be realized


FXT1: Texture Compression BenefitsFXT1: Texture Compression Benefits

— No perceptible loss in image quality

— Enables use of very high-resolution textures

— Decreases memory storage requirements

— Decreases memory bandwidth requirements

— Maximizes available memory bandwidth

— Increases sustained fill-rate and frame rates


— Increases total number of textures available for rendering Store up to 8x number of compressed textures in same space

that used to be required for just one

— Enables use of higher resolution textures for better image quality

Uncompressed 2048x2048 32bpt texture requires 16MB memory (almost unusable on current hardware) compared 2MB when FXT1 compressed



— Permits use of more textures per polygon for advanced effects FXT1 texture compression makes more bandwidth

available

More textures can be used to render a given object allowing for effects like bump mapping, light maps, detail textures, etc.



— Lowers bandwidth requirements for better fill rate performance Increases number of texels fed to raster engine

Increases fill rate

Increases frame rates



— Encoding:

Divides image up into multiple 4x4 or 4x8 texel blocks

Individual texel blocks encoded using one of four different algorithms to maximize image quality

Results in 4 bit-per-texel storage and bandwidth requirements

Compressed textures can be encoded during installation, when a scene loads, or stored on CD


FXT1: Texture Compression How does it work?FXT1: Texture Compression How does it work?

— Decoding:

Compressed textures are stored natively in system memory or local frame buffer memory

Decompression is performed by 3D hardware accelerator during run-time only when the compressed texture is used for rendering

Each texel block includes a 2-bit field used to identify which of the four different compression algorithms is used

— Open Source format

— Cross Platform Support Windows, Macintosh, Linux and BeOS

— Includes free tools for encoding and decoding No royalty or licensing fees for content developers or

independent hardware vendors

Allows anyone to innovate with higher quality and/or faster implementations


FXT1: Texture Compression What FXT1 delivers that other texture compression doesn’t


— Highest possible image quality

Multiple algorithms used for every image to deliver most precise reproduction of original artwork

— Best compression ratio for textures with more than single bit alpha FXT1 uses 4 bpt compression for textures even

with multi-bit Alpha channels -- reduces storage requirements by 1/3

— Free

S3TC

FXT1

Single algorithm

Up to four different algorithms

FXT1: Texture Compression How does it compare to S3TC?


FXT1 retains more detail than S3TC by using four different encoding algorithms for each image. This contrasts with only one algorithm used by S3TC.




With 4 different techniques used to compress each image, FXT1™ provides the most accurate image reproduction as measured by Root Mean Square error of each encoding algorithm
