How to read vertices from vertex buffer in Direct3d11

Question

I have a question regarding vertex buffers. How does one read the vertices from the vertex buffer in D3D11? I want to get a particular vertex\'s position for calculations, i

Answer 1

The following code only get the address of the mapped resource, you didn't read anything before Unmap.

vert = (VERTEX*) ms.pData;

If you want to read data from the mapped resource, first allocate enough memory, then use memcpy to copy the data, I don't know your VERTEX structure, so I suppose vert is void*, you can convert it yourself

vert = new BYTE[ms.DepthPitch];
memcpy(vert, ms.pData, ms.DepthPitch];
