Reinterpret RTV as SRV in another format

Case 1: device->CreatePlacedResource(heap, 0, resDesc1, state_render_target, nullptr, IID..(resource1)) // success device->CreatePlacedResource(heap, 0, resDesc1, state_pixel_shader, nullptr, IID..(resource2)) // success device->CreateCommitedResource(...) fails Case 2: (what I want to accomplish) device->CreatePlacedResource(heap, 0, resDesc1, state_render_target, nullptr, IID..(resource1)) // success device->CreatePlacedResource(heap, 0, resDesc2, state_pixel_shader, nullptr, IID..(resource2)) // fails (total size of texture described in resDesc2 is equal or less than the heap used, both cases fail) I need to render to RTV in one format then without copying, to read from it as SRV using another format. Is this the way I should try to do it?

The space where the triangles do not cover becomes the mask(mask-out). I don't even care about the clear color of that pixels. They're totally ignored.

I maybe should explain that I am not rendering 3D but GPGPU. So no 3D inside the 3D or something.
