This closes #32 The changes in this pull-request are mostly the same, but this one can be merged and the repo isn't deleted ;)

Will you add even the second commit with the integration of NV_DX_interop2 extension and WPF sample?

This is much faster than the original implementation!

To make it work on Intel HD Graphics 5500, I had to add a call to DXSetResourceShareHandleNV in method FastGLControl.ResizeRendering - like so:

` IntPtr textureShareHandle = IntPtr.Zero; _texture = new Texture(_device, (int)ActualWidth, (int)ActualHeight, 1, Usage.None, Format.X8R8G8B8, Pool.Default, ref textureShareHandle); _renderBuffer = _texture.GetSurfaceLevel(0);

_gl.DXSetResourceShareHandleNV(_texture.ComPointer, textureShareHandle);

_glRenderBufferHandle = _gl.DXRegisterObjectNV(_dxDeviceGLHandle, _texture.ComPointer, _glRenderBufferName, OpenGL.GL_TEXTURE_2D, OpenGLExNV.WGL_ACCESS_READ_WRITE_NV); `

Do you think it might be possible to add depth test support? The following call does not help - probably because there is no depth buffer: _gl.Enable(OpenGL.GL_DEPTH_TEST);

This is merged now! Am finally doing some spring cleaning, the PR was #175 in the end as there were conflicts

Wow - didn't think it'll still make it :D

dwmkerr commented 4 years ago

Yes, it's been quite a while, so sorry about that!

@dwmkerr it's ok, no worries^^ was just very surprised when I saw that email :D

Just a shame I didn't manage to change the name in the commits before merging them
