[color="#2A2A2A"]When a buffer is used as a render target, depth-stencil testing and multiple render targets are not supported.[/quote].
And the only way to use SlimDX in WPF is to use texture as render target?
Is there any way to make Z-buffer working in SlimDX WPF?
SlimDX WPF No Z-Buffer

I spend a lot of time to find why z-buffer don't work in my modified WpfSample10 and then founded information from microsoft site(http://msdn.microsof...4(v=vs.85).aspx):

As I understand it, the documentation says that a plain d3d10 buffer (and not a texture) can be bound as a RenderTargetView (though I have never tested this kind of bindings) but then you cannot bind any depthstencilviews.
Have you tried in the WPF sample to create a separate render target/depth stencil buffer, render your d3d10 scene to it, and then copy the resulting rendertarget to the shared d3d9 surface?

Yes, I do in such way, this part of code left from sample and it works pretty well except Z-Buffer.
RenderTarget Texture initialization:
var renderTexDesc = new Texture2DDescription()
{
BindFlags = BindFlags.RenderTarget | BindFlags.ShaderResource,
Format = Format.B8G8R8A8_UNorm,
Width = WindowWidth,
Height = WindowHeight,
MipLevels = 1,
SampleDescription = new SampleDescription(1, 0),
Usage = ResourceUsage.Default,
OptionFlags = ResourceOptionFlags.Shared,
CpuAccessFlags = CpuAccessFlags.None,
ArraySize = 1
};
SharedTexture = new Texture2D(device, renderTexDesc);
sampleRenderView = new RenderTargetView(device, SharedTexture);DepthStencil initialization:
var depthDesc = new Texture2DDescription()
{
BindFlags = BindFlags.DepthStencil,
Format = Format.D32_Float,
Width = WindowWidth,
Height = WindowHeight,
MipLevels = 1,
SampleDescription = new SampleDescription(1, 0),
Usage = ResourceUsage.Default,
OptionFlags = ResourceOptionFlags.None,
CpuAccessFlags = CpuAccessFlags.None,
ArraySize = 1
};
DepthTexture = new Texture2D(device, depthDesc);
depthStencilView = new DepthStencilView(device, DepthTexture);
var dsDesc = new DepthStencilStateDescription
{
IsDepthEnabled = true,
IsStencilEnabled = false,
DepthWriteMask = DepthWriteMask.All,
DepthComparison = Comparison.Less
};
depthStencilState = DepthStencilState.FromDescription(device, dsDesc);Rasterizer initialization:
var rasterizerState = new RasterizerStateDescription()
{
CullMode = CullMode.None,
FillMode = FillMode.Solid,
IsFrontCounterclockwise = false,
DepthBias = 0,
DepthBiasClamp = 0,
SlopeScaledDepthBias = 0,
IsDepthClipEnabled = true,
IsScissorEnabled = false,
IsMultisampleEnabled = true,
IsAntialiasedLineEnabled = true
};
device.Rasterizer.State = RasterizerState.FromDescription(device, rasterizerState);Render:
public void Render(int arg)
{
device.OutputMerger.DepthStencilState = depthStencilState;
device.OutputMerger.SetTargets(depthStencilView, sampleRenderView);
device.Rasterizer.SetViewports(new Viewport(0, 0, WindowWidth, WindowHeight, 0.0f, 1.0f));
device.ClearRenderTargetView(sampleRenderView, new Color4(0.0f, 0.0f, 0.0f));
device.ClearDepthStencilView(depthStencilView, DepthStencilClearFlags.Depth, 1.0f, 0);
Matrix worldMatrix = GetWorldViewProj(arg);
DataStream ds = new DataStream(worldMatrix.ToArray(), true, false);
SampleEffect.GetVariableByName("WorldViewProj").AsMatrix().SetMatrix(worldMatrix);
EffectTechnique technique = SampleEffect.GetTechniqueByIndex(0);
EffectPass pass = technique.GetPassByIndex(0);
for (int i = 0; i < technique.Description.PassCount; ++i)
{
pass.Apply();
renderDataManager.Render(worldMatrix);
}
device.Flush();
OnSceneRender();
}

Seems not exactly. What I was suggesting is that you create 2 render target buffer: one used with the z-buffer, but that is not shared (no ResourceOptionFlags.Shared on it). One that is shared, and receive a copy of the 1st render target (device.CopyResource between them)

In such way?

I ran into the exact same problem. Spent nearly a week to resolve this (using DX11) and utterly failed.
Looking forward to a solution.
EDIT:
I'm using a deferred renderer, thus i already tried the solution that Alexander proposed (copy non-shared mainbuffer to shared surface). No dice. Something screws up the z-buffer. I was already suspecting WPF to somehow interfere with the device. But then again, i have no idea...
EDIT cont:
I just recalled that i tested this without a shared texture. Instead of D3DImage, i used the WinFormsHost control in WPF and rendered directly to the handle (using a swapchain as usual). Now guess what, z-buffer is still broken. That's when i gave up, suspecting WPF to screw with my DX11 device.
If anyone knows anything about this, i'm nervous to get some real answers.

Yeah, it was my last hope too. And it's extremely puzzling to say the least. Also there's virtually no information about this to be found anywhere.
I wonder if the creators of (for example) SlimDXControl ever tested their code with anything else than a simple triangle - cause it appears they most certainly have not.
(along with a number of other devs that have blogged about WPF/DX10-11 interop)
After testing the hell out of this topic for a week i put in on the shelf with a big sign saying "FUTILE".
I guess there's no need to state how frustrating this is, especially since WPF and DirectX are developed by the same company.

I have just tested my code in WinForms, the same result, Z-Buffer do not work. May be any problems with shader?
struct VS_IN
{
float4 pos : POSITION;
float4 col : COLOR;
};
struct PS_IN
{
float4 pos : SV_POSITION;
float4 col : COLOR;
};
float4x4 WorldViewProj : WORLDVIEWPROJECTION;
PS_IN VS( VS_IN input )
{
PS_IN output = (PS_IN)0;
output.pos = mul(input.pos, WorldViewProj);
output.col = input.col;
return output;
}
float4 PS( PS_IN input ) : SV_Target
{
return input.col;
}
technique10 Render
{
pass P0
{
SetGeometryShader( 0 );
SetVertexShader( CompileShader( vs_4_0, VS() ) );
SetPixelShader( CompileShader( ps_4_0, PS() ) );
}
