ASTCformat
ASTCformat refers to the Adaptive Scalable Texture Compression (ASTC) scheme, a texture compression format designed to reduce memory footprint and bandwidth for real-time rendering while preserving image quality. Developed under the Khronos Group with contributions from Arm and other industry partners, ASTC was introduced to unify and improve upon prior mobile and desktop texture formats by offering flexible compression options and broad hardware support.
Technical overview: ASTC compresses 2D and, in capable implementations, 3D textures in fixed-size blocks. A single
Encoding and decoding: ASTC utilizes per-block color endpoints and index patterns to reconstruct texels during sampling.
Adoption and use: ASTC has broad hardware and API support, including modern GPUs and graphics APIs such
File formats and containers: ASTC textures are typically stored with the .astc extension and are commonly packaged
