2011.06.09 So, there is this guy who keeps asking about DX11 renderer progress and I figured I might as well explain it with some pictures :) Direct3D 11 is very different to D3D9, and this is the source of my problems. While I want the functionality it offers, I need to properly rewrite every part of the code. In fact the change is so big I created a separate project that is based on NAOMI emulator code but all it does is render one frame of previously captured data. Makes my life so much easier. D3D11 is a functional extension to version 10 interface except you work on context rather than the device itself, which is only used for creating new resources. This lets you create command lists for things like deferred rendering, though I stil use immediate mode. Unlike in 10, the reference counters are incremented by various Get* methods and this is more like it was in D3D9, so the behaviour was clearly reverted. And for the better I suppose - makes much more sense this way. The main problem is the grouping of various settings that I need to change individually, this was much easier on D3D9. While the new approach certainly speeds up things for games, I cannot make any assumptions about the 3D data I'm processing and I can't sort it nicely either, so I have to prepare many object with all possible settings well in advance and select the right one when the time comes. Doesn't seem that complicated, eh? Well, it's actually is much more bothersome than it sounds. Anyway, I decided to start with the basics and then, once it all more or less works, try to add the layer peeling system for per-pixel depth sorting. There will be another major obstacle on the way, namely the fact that I can have different blending operations mixed in together. So I will need to store the blending instruction data along with the pixels and have pixel shader combine the fragments properly. Which is not going to be easy or super fast :) Still, no point in worrying about that now. It's either that or full software rendering if you want proper PVR2 emulation. Here are some sample screenshots I took along the way, so that you could see there is progress. Note that I already ported and tested the text display class - though with just one frame being rendered the log is much better target for debug output. http://pics.livejournal.com/dknute/pic/000x7pyx/s320x240 http://pics.livejournal.com/dknute/pic/000x85yh/s320x240 http://pics.livejournal.com/dknute/pic/000x9wsk/s320x240 http://pics.livejournal.com/dknute/pic/000xae0f/s320x240 These two are different becase I had to change the capture data format a few times: http://pics.livejournal.com/dknute/pic/000xbhph/s320x240 http://pics.livejournal.com/dknute/pic/000xch31/s320x240 Anyone wants to guess what game is this? Should be pretty easy by now :) EDIT: We have a winner! It's Zero Gunner 2. http://pics.livejournal.com/dknute/pic/000xd9px/s320x240 ______________________________________________________________________________ 來源：http://dknute.livejournal.com/39098.html --
