I am sorry for the problems with the forum. I will check the spam filter settings again and see if there is anything I can do to improve that.

Now to your question.
From what you have written I think that you should be able to use the texture2D directly as it is on the GPU without copying it to main memory, converting it to GDI+ bitmap, then to WPF bitmap. And from there in DXEngine back to DirectX shader resource view and sending it back to GPU. There is a lot of overhead especially with sending the image from the gpu and back.

To try this use the following code to first create a ShaderResourceView from the texture2D object:

Code:

var resourceViewDescription = new ShaderResourceViewDescription
{
     Format = [enter format],
     Dimension = SharpDX.Direct3D.ShaderResourceViewDimension.Texture2D,
     Texture2D = new ShaderResourceViewDescription.Texture2DResource
     {
          MipLevels = 1,
          MostDetailedMip = 0
     }
};

var shaderResourceView = new ShaderResourceView(dxViewportView.DXScene.DXDevice.Device, texture2D, resourceViewDescription);

// Do not forget to dispose the shaderResourceView when it is not used any more.
// This can be done with using DisposeList object - for example:
_disposables.Add(shaderResourceView);

Then you can create a DXEngine material that will use that texture:

Code:

var standardMaterial = new StandardMaterial()
{
   // Set ShaderResourceView into array of diffuse textures
  DiffuseTextures = new ShaderResourceView[] { shaderResourceView },

  // When showing texture, the DiffuseColor represents a color mask - each color from texture is multiplied with DiffuseColor (White preserves the original color)
  DiffuseColor = Colors.White.ToColor3()
};

_disposables.Add(standardMaterial);

You can then use the standardMaterial to create a MeshObjectNode or if you are using WPF 3D objects, you can assign it to WPF Material with:

Code:

diffuseMaterial = new DiffuseMaterial();
diffuseMaterial.SetUsedDXMaterial(standardMaterial);

This will use the standardMaterial whenever the DXEngine will render an object with the diffuseMaterial.


I hope that this code will work for you.
