| 779 | * exaTryMagicTwoPassCompositeHelper implements PictOpOver using two passes of | |||
| 780 | * simpler operations PictOpOutReverse and PictOpAdd. Mainly used for component | |||
| 781 | * alpha and limited 1-tmu cards. | |||
| 782 | * | |||
| 783 | * From http://anholt.livejournal.com/32058.html: | |||
| 784 | * | |||
| 785 | * The trouble is that component-alpha rendering requires two different sources | |||
| 786 | * for blending: one for the source value to the blender, which is the | |||
| 787 | * per-channel multiplication of source and mask, and one for the source alpha | |||
| 788 | * for multiplying with the destination channels, which is the multiplication | |||
| 789 | * of the source channels by the mask alpha. So the equation for Over is: | |||
| 790 | * | |||
| 791 | * dst.A = src.A * mask.A + (1 - (src.A * mask.A)) * dst.A | |||
| 792 | * dst.R = src.R * mask.R + (1 - (src.A * mask.R)) * dst.R | |||
| 793 | * dst.G = src.G * mask.G + (1 - (src.A * mask.G)) * dst.G | |||
| 794 | * dst.B = src.B * mask.B + (1 - (src.A * mask.B)) * dst.B | |||
| 795 | * | |||
| 796 | * But we can do some simpler operations, right? How about PictOpOutReverse, | |||
| 797 | * which has a source factor of 0 and dest factor of (1 - source alpha). We | |||
| 798 | * can get the source alpha value (srca.X = src.A * mask.X) out of the texture | |||
| 799 | * blenders pretty easily. So we can do a component-alpha OutReverse, which | |||
| 800 | * gets us: | |||
| 801 | * | |||
| 802 | * dst.A = 0 + (1 - (src.A * mask.A)) * dst.A | |||
| 803 | * dst.R = 0 + (1 - (src.A * mask.R)) * dst.R | |||
| 804 | * dst.G = 0 + (1 - (src.A * mask.G)) * dst.G | |||
| 805 | * dst.B = 0 + (1 - (src.A * mask.B)) * dst.B | |||
| 806 | * | |||
| 807 | * OK. And if an op doesn't use the source alpha value for the destination | |||
| 808 | * factor, then we can do the channel multiplication in the texture blenders | |||
| 809 | * to get the source value, and ignore the source alpha that we wouldn't use. | |||
| 810 | * We've supported this in the Radeon driver for a long time. An example would | |||
| 811 | * be PictOpAdd, which does: | |||
| 812 | * | |||
| 813 | * dst.A = src.A * mask.A + dst.A | |||
| 814 | * dst.R = src.R * mask.R + dst.R | |||
| 815 | * dst.G = src.G * mask.G + dst.G | |||
| 816 | * dst.B = src.B * mask.B + dst.B | |||
| 817 | * | |||
| 818 | * Hey, this looks good! If we do a PictOpOutReverse and then a PictOpAdd right | |||
| 819 | * after it, we get: | |||
| 820 | * | |||
| 821 | * dst.A = src.A * mask.A + ((1 - (src.A * mask.A)) * dst.A) | |||
| 822 | * dst.R = src.R * mask.R + ((1 - (src.A * mask.R)) * dst.R) | |||
| 823 | * dst.G = src.G * mask.G + ((1 - (src.A * mask.G)) * dst.G) | |||
| 824 | * dst.B = src.B * mask.B + ((1 - (src.A * mask.B)) * dst.B) | |||
