A D3D11_USAGE_STAGING Resource cannot be bound to any parts of the graphics pipeline

I'm trying to Create RWStrutruedBuffer with a D3D11_USAGE_STAGING for cpu access

.

error: D3D11_USAGE_STAGING Resource cannot be bound to any parts of the graphics pipeline.

  1. How can get the RWStrutruedBuffer from GPU to CPU? I need the result.thanks for every.

  2. Should I Copy a Resource with a D3D11_USAGE_DEFAULT flag to a Resource with D3D11_USAGE_STAGING ,then read it form CPU?

Solution

  • I found the answer just like step 2,I need to Copy resource to other resource that was created with a D3D11_USAGE_STAGING flag,then use map with D3D11_MAP_READ,finally read it.
