# 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.

## Build Instructions
Binaries for ISPC v1.9.2 need to be obtained separately (e.g., from [the ISPC
repo](https://ispc.github.io/downloads.html) or [the SourceForge
mirror](http://sourceforge.net/projects/ispcmirror/files/v1.9.2/)). 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.
