/**
|
|
* exaTryMagicTwoPassCompositeHelper implements PictOpOver using two passes of
|
|
* simpler operations PictOpOutReverse and PictOpAdd. Mainly used for component
|
|
* alpha and limited 1-tmu cards.
|
|
*
|
|
* From http://anholt.livejournal.com/32058.html:
|
|
*
|
|
* The trouble is that component-alpha rendering requires two different sources
|
|
* for blending: one for the source value to the blender, which is the
|
|
* per-channel multiplication of source and mask, and one for the source alpha
|
|
* for multiplying with the destination channels, which is the multiplication
|
|
* of the source channels by the mask alpha. So the equation for Over is:
|
|
*
|
|
* dst.A = src.A * mask.A + (1 - (src.A * mask.A)) * dst.A
|
|
* dst.R = src.R * mask.R + (1 - (src.A * mask.R)) * dst.R
|
|
* dst.G = src.G * mask.G + (1 - (src.A * mask.G)) * dst.G
|
|
* dst.B = src.B * mask.B + (1 - (src.A * mask.B)) * dst.B
|
|
*
|
|
* But we can do some simpler operations, right? How about PictOpOutReverse,
|
|
* which has a source factor of 0 and dest factor of (1 - source alpha). We
|
|
* can get the source alpha value (srca.X = src.A * mask.X) out of the texture
|
|
* blenders pretty easily. So we can do a component-alpha OutReverse, which
|
|
* gets us:
|
|
*
|
|
* dst.A = 0 + (1 - (src.A * mask.A)) * dst.A
|
|
* dst.R = 0 + (1 - (src.A * mask.R)) * dst.R
|
|
* dst.G = 0 + (1 - (src.A * mask.G)) * dst.G
|
|
* dst.B = 0 + (1 - (src.A * mask.B)) * dst.B
|
|
*
|
|
* OK. And if an op doesn't use the source alpha value for the destination
|
|
* factor, then we can do the channel multiplication in the texture blenders
|
|
* to get the source value, and ignore the source alpha that we wouldn't use.
|
|
* We've supported this in the Radeon driver for a long time. An example would
|
|
* be PictOpAdd, which does:
|
|
*
|
|
* dst.A = src.A * mask.A + dst.A
|
|
* dst.R = src.R * mask.R + dst.R
|
|
* dst.G = src.G * mask.G + dst.G
|
|
* dst.B = src.B * mask.B + dst.B
|
|
*
|
|
* Hey, this looks good! If we do a PictOpOutReverse and then a PictOpAdd right
|
|
* after it, we get:
|
|
*
|
|
* dst.A = src.A * mask.A + ((1 - (src.A * mask.A)) * dst.A)
|
|
* dst.R = src.R * mask.R + ((1 - (src.A * mask.R)) * dst.R)
|
|
* dst.G = src.G * mask.G + ((1 - (src.A * mask.G)) * dst.G)
|
|
* dst.B = src.B * mask.B + ((1 - (src.A * mask.B)) * dst.B)
