Finally, a DirectX 10 video driver for Irrlicht

[slavik262]

Alright. I didn't know it could be done like that. I was under the impression that you can only have a single SDK installed at one time and that just copying the headers wouldn't work properly.

AFAIK, dx8 support was completely removed from the dx10/dx11 SDKs. This would make an Irrlicht version with dx8 and dx10/dx11 impossible. Even more due to the large changes between those versions, which will probably also make library copying nearly impossible. Anyway, this seems to be a minor problem compared to creating the necessary drivers first

Hi people.

Now working particle system (with dynamic vertex/index buffers), and some transparent materials, see:



My difficult now is to adjust renderer system to handle alpha, material types and lightning on/off. To much ifs on shader .

[slavik262]

Yeah, the shader pipeline isn't usually very happy with lots of branching. Is there any way you could handle the logic on the CPU?

[3DModelerMan]

Is this still under development? I think I have a good idea for the shader flags. false is equal to 0, so multiplying the diffuse light factor, by the lighting flag... would cause the lighting to be disabled when it's false, and be unchanged when it's true.

[slavik262]

It would be more streamlined to just have separate shaders altogether, and would probably save on performance. Granted, DX10 users probably have decent hardware, but even with SM 3 and 4, branching should be a last resort. Why make the same decision over and over hundreds of times (per vertex, or worse, per pixel) unless you absolutely have to?

Do shaders work with this yet? I want to test it out cause I'm getting a DX11 card soon.

Hello people, I was distant from the project, but I'm back.

I tried this technique, but it would be very cumbersome and difficult to integrate into the engine. But yes, can be done. Ogre3D, in you RenderSystemDX11 do this, but is still incomplete.

Right now, I'm having trouble with normal and parllax shaders. I simply can't make it works. I tried to transpose the logic from Direct3D 9 renderers, but don't works. Some objects flick, other disappear.

I'll try to copy some logic from DX 10 books and adapt. I exhausted the possibilities doing simply porting.

If anyone can help, I'll be very happy!!

[3DModelerMan]

Are you going to release this under ZLIB ever? I want to start using it in my project really soon.

[evandromillian]

Hi people. I have good news. I see that, using DirectX 11 and Effect framework, we can pass shader interfaces statically in techniques, removing the switchs from the code.

This can also solve problem with alpha handling, where when alpha is disabled we can use a interface that does nothing, and so on.

I think that with this features we can deprecated DirectX 10 interface. Will be more productive work with a more evolved API.

I will keep all informed.

About ZLib licence, I don't have any problem to change licence, but Goggle Code don't have. Can someone provide an user and password in Irrlicht Sourceforge repository?

Thanks once more for the support.

[3DModelerMan]

Alright! I can't wait to try this out. I just got a DirectX11 graphics card so I can use all the latest techniques.

[3DModelerMan]

Does anyone have 64 bit binaries of this? I can't get it to compile.

[evandromillian]

Are you said DX 11 binaries?

[3DModelerMan]

64 bit DX11 binaries. I'm working on a 64 bit machine now.

[evandromillian]

These binaries are inside DX SDK instalation. In Lib directory, there are two folders, x86 e x64.
