There may be a way to do this already....
At this site
there is a pixel shader example of updating a writeable bitmap.
I want to do almost the exact same thing, using a pixel shader.
I want to COPY a bitmap that was created or built in c++ (the code can not be translated into C# )
So basically, I want to have
1) Texture to be updated (the writeable bitmap, just as in pixel shader example at above listed site.
2) A SECOND Texture, but this texture lives in C++ land inside a COM object.
My problem, it may or may not be very easy to solve, is to reference this second texture in the pixel shader. How do I do this?
(I basically want to copy bmp, using a pixel shader, rather than via SetPixel api or something like that)
So basically I'm copying using the GPU rather than the CPU....
