# Fast ISPC Texture Compressor This repository contains a texture compression library for the following formats: * BC6H (FP16 HDR input) * BC7 * ASTC (LDR, block sizes up to 8x8) * ETC1 * BC1, BC3 (aka DXT1, DXT5) and BC4, BC5 (aka ATI1N, ATI2N) The library uses the [ISPC compiler](https://ispc.github.io/) to generate CPU SIMD-optimized compression algorithms. For more information, see the [Fast ISPC Texture Compressor](https://software.intel.com/en-us/articles/fast-ispc-texture-compressor-update) article on Intel Developer Zone.  ## License Copyright 2017 Intel Corporation Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Download the appropriate compiler for your target, and place the binary in the following directories: - ISPC/linux/ - ISPC/osx/ - ISPC/win/ Source for the ISPC Texture Compressor library is under `ispc_texcomp/`. Source for a sample that demonstrates the tradeoffs between the supported compression variants is under `ISPC Texture Compressor/`. #### Windows * The build projects use Visual Studio 2017, Windows Tools 1.4.1, and the Windows 10 April 2018 Update SDK (17134) * Use `ispc_texcomp\ispc_texcomp.vcxproj` to build the ISPC Texture Compressor library * Use `ISPC Texture Compressor\ISPC Texture Compressor.sln` to build and run the sample #### Mac OS X: * The build has been tested with Xcode 7.3 with minimum OS X deployment version set to 10.9 * Use `ispc_texcomp.xcodeproj` to build the ISPC Texture Compressor library * dylib install name is set to `@executable_path/../Frameworks/$(EXECUTABLE_PATH)` * The sample application is not available on OS X. #### Linux: * Use `make -f Makefile.linux` to build the ISPC Texture Compressor library * The sample application is not available on Linux.
