New Compression Formats • Two new compression formats: BC6H & BC7 • BC6H: HDR texture compression — RGB only — Signed and Unsigned — 16 bit floating point values — 6:1 compression • BC7: High Quality LDR texture compression — RGB with optional Alpha — 3:1 (RGB) or 4:1 (RGBA) compression
BC6H Compression Quality • Objective: – Replace uncompressed FP16x4 and RGBE textures BC6H LUVW RGBE FP16x4 uffizi cross 63.75 63 70 108 stpeters cross 62.97 66 69 95 rnl cross 62.99 70 72 129 grace cross 61.72 75 64 133 Average PSNR 62.62 68.5 68.75 <strong>11</strong>6.25 Average PSNR / Bits per pixel 7.83 4.28 2.15 1.82
