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

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
t e c h n o l o g yi n n o v a t i o n
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
t e c h n o l o g yi n n o v a t i o n
— 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
t e c h n o l o g yi n n o v a t i o n
FXT1: Texture Compression BenefitsFXT1: Texture Compression Benefits
— 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.

FXT1: Texture Compression BenefitsFXT1: Texture Compression Benefits
— 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
t e c h n o l o g yi n n o v a t i o n
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

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

FXT1: Texture Compression How does it compare to S3TC?
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.
