Finally, a DirectX 10 video driver for Irrlicht

[Nadro]

This explains the situation

[Mel]

I`ve been seeing the shader for the fixed pipeline emulation, i would like to comment the diference between EMT_SPHERE_MAP and EMT_REFLECTION_2_LAYER.

While both look very similar, they aren't alike at all. You see. In EMT_SPHERE_MAP the vector used to map the texture sample is the normalized normal of the vertex as seen in view space, but multiplied by 0.5 and added 0.5 to sample in the right range, while the EMT_REFLECTION_2_LAYER uses the normalized reflected view vector using the vertex normal, in view space, as the "normal" to reflect this vector.

Also congrats, it is an awesome work

any news on DX10 or 11 driver progress?

[zerochen]

i didnt have much time this week. so i have only minor fixes.
i began to implement the bridgecall class but not finished right now.

1: In example no. 10 we can see problems related to depth write by transparent objects.
2: n example no. 11 when we rotate a camera in some places, some artifacts are visible (bad tris are connected with gui I think, it's good visible in diffuse mode).

2: i think i fixed this but not really sure. I had this problem very rarely.
1: i guess that is a error in the fixed function shader. but my knowledge of shaders are very limited. so i can not fix it.

@Mel
can you provide a patch for this?

[Mel]

i can try but i am unsure of how thing works, i haven't tested the driver properly, only have seen through the shaders.

[zerochen]

hi,

here is a new update for the driver:

update.patch

changes:
- added CD3D11CallBridge (now we reached almost the same speed as the dx9 driver)
- added DX 11.1 support
- general clean up

@nadro

In example no. 11 when we rotate a camera in some places, some artifacts are visible (bad tris are connected with gui I think, it's good visible in diffuse mode).

can you confirm that it is fixed?

i think next feature is the fvf.
have you a example for that in the ogles branch or somewhere else?

[Nadro]

Merged with branch I checked a performance and now it looks like this driver is really well optimized (sometimes D3D9 is faster mainly in 2D draw operations, sometimes D3D11). Good work!

What about bugs:
- example no. 11 is fixed now.
- in example no. 13, RT texture is wrong.

Currently I don't see other problems.

What about FVF?
You can see working implementations (check stuff which contain VertexDescriptor word) in shader-pipeline branch for OGL driver (as I said before it need some fixes related to FVF and COpenGLBridgeCalls) and D3D9 (it works properly).

I updated to the latest revision:

CD3D11Driver.cpp(303): error C2065: 'D3D_FEATURE_LEVEL_11_1' : undeclared identifier

Using the Microsoft DirectX SDK (June 2010)

EDIT
Nevermind, just found this commend in the compile config

//! Only define _IRR_COMPILE_WITH_DIRECT3D_11_ if you have an appropriate DXSDK
//! Download: http://msdn.microsoft.com/en-us/windows ... 52363.aspx

I tried to compile this version of irrlicht and informs me the following error, I have the SDK referred in DX11 driver.

What do I need?

Greetings.

Probably You don't use VS2011 project, so You have to add CVertexDescription and D3D11* files to your Irrlicht project (other projects are missing those files).

[etreum79]

Thank you very much Nandro, compile everything and even got several demos, but for example 008 SpecialFX only get to see the black window.

I guess this is still very recent, and perhaps this demo does not work yet.

Greetings.

EDIT: all the demos DX11 driver is choosing the black window.

[zerochen]

all examples might work.

did you try to make a clean up?
any errors in the console window?
which dx version is supported by your graphic card?

[Nadro]

Please check console log. Do You see something like a:

Could not load library: d3dcompiler_46.dll

The latest MS SDK doesn't install properly some files to system32/ dir, so You have to copy them manually from sdk directory to system32 or irrlicht bin folder.

[etreum79]

Perform cleaning and recompile everything ok.
But the window goes black in all the examples, I set the console if the dll calls, but I bet that error is this.

thank you very much to both this evening when I get home I will check.

regards

i added a postbuild step with the lastest patch that cares about the file. it copies the file to the bin folder. haven't you added this part of patch?
