示例1: moveptr
DepthStencilView::DepthStencilView(DeviceContext& context)
{
// get the currently bound depth stencil view from the context
ID3D::DepthStencilView* rawPtr = nullptr;
context.GetUnderlying()->OMGetRenderTargets(0, nullptr, &rawPtr);
_underlying = moveptr(rawPtr);
}示例2: moveptr
IndexBuffer::IndexBuffer(DeviceContext& context)
{
ID3D::Buffer* rawPtr = nullptr;
DXGI_FORMAT fmt = DXGI_FORMAT_UNKNOWN;
unsigned offset = 0;
context.GetUnderlying()->IAGetIndexBuffer(&rawPtr, &fmt, &offset);
_underlying = moveptr(rawPtr);
}示例3: XlCopyMemory
void ConstantBuffer::Update(DeviceContext& context, const void* data, size_t byteCount)
{
// context.GetUnderlying()->UpdateSubresource(
// _underlying, 0, nullptr, data, byteCount, byteCount);
D3D11_MAPPED_SUBRESOURCE result;
ID3D::DeviceContext* devContext = context.GetUnderlying();
HRESULT hresult = devContext->Map(_underlying.get(), 0, D3D11_MAP_WRITE_DISCARD, 0, &result);
if (SUCCEEDED(hresult) && result.pData) {
XlCopyMemory(result.pData, data, byteCount);
