DX11 plugin #192

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
Notes to self:

1: Mudlord needs to make a DX11 port of the DX9 plugin.
2: Mudlord needs to port the shaders and do fixed function emulation.
3: Do code on private SVN *before* committing to main nulldc tree.

What is the expected output? What do you see instead?

The expected output is: Proper Z with antialiasing, because of increased depth 
precision.

But instead I see: Improper Z sorting due to DX9 not supporting 32bit floating 
Z.

What version of the product are you using? What build? What plugins?

I use version: Latest nullDC Debug SVN with latest debug plugins

On what kind of system?
My system specifications are as follows:

Operating System: Windows 7 Ultimate x64
CPU: AMD Phenom II 550 @ 3.1Ghz
Video Card: ATI Radeon 5770 with 1GB RAM
Sound Card: Onboard 7.1 Via based.

Mail ain't enough it seems.

will this D3D11 plugin have D3D10 fallbacks? D3D10 supports 32FPZ as well

You can use Dx10 HW with D3D11. The float depth support should get rid of the 
z-fighting, and the Out of Order Transparency should get rid of the sorting 
problems. But the latter does require Dx11 HW I think.

Actually, the current dx9 code is a mess-- you'l probably have more luck 
writing something form the beginning :p. Been wanting to do this for some time, 
but never really got around more than dx10 init code

out of order transparency works on D3D10 as well.

nvidia's depth peeling has been nominated to be a form of out of order 
transparency.

heck, apparently Nvidia has supported this since the Geforce 3
http://developer.nvidia.com/object/order_independent_transparency.html

I expect it may be a D3D11 requirement, which im sure the 4xx cards will 
support from the go.

Using depth peeling to achieve OIT? Might as well use software rendering 
instead. Same effect, same speed, but with s/w rendering being more accurate. :p

Reverse OIT is apparently nearly hitless.

@drkRaz: Fine, doing it with MSVC2008. :P

The pvr hardware implements a version of depth peeling

indeed it does drk.

surely we can write a custom shader to emulate PVR GPU Depth peeling?

We are salvaging what we can from the old D3D9 plugin, as some is still useful. 
Really, the shaders, rasterization etc, needs to be redone.

First initial commits.
Added code base.
