Technické post-mortem z konverze hry Zaklínač 2 na Xbox 360

At first we thought it wouldn't be possible, but we worked out a solution for it: we compressed from three g-buffer surfaces plus depth to two g-buffer surfaces - for example, by packing two values on one byte.

Hitting 30FPS in 90 per cent of the game was a really big challenge that we finally managed to achieve, but still, the biggest problem for a very long time was colour precision. We used 10-bit render targets instead of 16 for HDR, and it was huge problem for our artists; they were complaining and crying all the time about what we have done with their beautiful game

Xbox 360 has its own specific output colour/gamma curve, different from PCs, and TV sets have totally different colour rendering from monitors designed for gamers and office work. We had lots of issues like overexposure, ugly colour-banding in shadows, strange colours and wrong gamma.

Omlouvám se, jak se to řekne česky? V AJ mluví o bokeh depth of field.
