This article and the attached sample code project were written by Marc Fauconneau Dufresne at Intel Corp.
This sample extends our state of the art BC7 Texture compressor with BC6H (DX11 HDR texture format) support. We use a similar approach to quick partition filtering, selection and refinement, along with an effective search strategy to take advantage of the B6CH endpoint transform. SIMD instruction sets are exploited using the Intel SPMD Compiler. Various quality/performance trade-offs are offered.
