Direct3D 11 will have tessellation for smoother curves and finer details. The new compute shader will make postprocessing faster and easier. You'll need Direct3D 11 to have the best graphics, and this talk will show you how you can get started using current generation hardware.

9. Switchable DX10/DX11 support examples // using D3D10 requires dxgi.lib and D3D11 beta requires dxgi_beta.lib and if we // link with only one through the common method then it crashes when creating // the D3D device. so instead conditionally link with the // correct dxgi library here for now --johan #ifdef DICE_D3D11_ENABLE #pragma comment(lib, "dxgi_beta.lib") #else #pragma comment(lib, "dxgi.lib") #endif // Setting a shader takes an extra parameter on D3D11: ID3D11ClassLinkage // which is used for the D3D11 subroutine support (which we don’t use) #ifdef DICE_D3D11_ENABLE m_deviceContext->PSSetShader(solution.pixelPermutation->shader, nullptr, 0); #else m_deviceContext->PSSetShader(solution.pixelPermutation->shader); #endif

10. Mapping buffers on DX10 vs DX11 #ifdef DICE_D3D11_ENABLE D3D11_MAPPED_SUBRESOURCE mappedResource; DICE_SAFE_DX(m_deviceContext->Map( m_functionConstantBuffers[type], // cbuffer 0, // subresource D3D11_MAP_WRITE_DISCARD, // map type 0, // map flags &mappedResource)); // map resource data = reinterpret_cast<Vec*>(mappedResource.pData); // fill in data m_deviceContext->Unmap(m_functionConstantBuffers[type], 0); #else DICE_SAFE_DX(m_functionConstantBuffers[type]->Map( D3D10_MAP_WRITE_DISCARD, // map type 0, // map flags (void**)&data)); // data // fill in data m_functionConstantBuffers[type]->Unmap(); #endif
