Examples

The D3D12Bundles sample uses ID3D12DescriptorHeap::GetGPUDescriptorHandleForHeapStart as follows:

C++


ID3D12DescriptorHeap* ppHeaps[] = { pCbvSrvDescriptorHeap, pSamplerDescriptorHeap };
pCommandList->SetDescriptorHeaps(_countof(ppHeaps), ppHeaps);
pCommandList->IASetPrimitiveTopology(D3D_PRIMITIVE_TOPOLOGY_TRIANGLELIST);

pCommandList->IASetIndexBuffer(pIndexBufferViewDesc);

pCommandList->IASetVertexBuffers(0, 1, pVertexBufferViewDesc);

pCommandList->SetGraphicsRootDescriptorTable(0, pCbvSrvDescriptorHeap->GetGPUDescriptorHandleForHeapStart());
pCommandList->SetGraphicsRootDescriptorTable(1, pSamplerDescriptorHeap->GetGPUDescriptorHandleForHeapStart());

Refer to the Example Code in the D3D12 Reference.
