Direct3D is a graphics API (Application Programming Interface) developed by Microsoft for creating 3D graphics on Windows platforms. Feature Levels in Direct3D represent a set of capabilities and features that a graphics device supports.
// Create a Direct3D 11.1 device IDXGIDevice* dxgiDevice; D3D11CreateDevice( nullptr, // Adapter D3D_DRIVER_TYPE_HARDWARE, // Driver type nullptr, // Software 0, // Flags nullptr, // Feature levels 1, // Num feature levels D3D11_SDK_VERSION, // SDK version &dxgiDevice, nullptr, nullptr );
// Check the feature level UINT featureLevel; dxgiDevice->GetFeatureLevel(&featureLevel); if (featureLevel >= D3D_FEATURE_LEVEL_11_1) { // Use Feature Level 11.1 } else { // Fallback to a lower feature level }
If you're a developer looking to create an application that uses Direct3D Feature Level 11.1, here's a simple code snippet to get you started:
