DiligentCore is a low-level, cross-platform rendering library designed to provide a modern graphics abstraction layer over Direct3D11, Direct3D12, OpenGL, Vulkan, and Metal. It’s aimed at developers building high-performance rendering engines and scientific visualization tools. DiligentCore gives precise control over GPU resources and rendering pipelines, while also abstracting away platform-specific boilerplate. The library is modular, extensible, and well-suited for projects that require direct access to modern graphics APIs while maintaining portability and scalability.
