Vulkan
Vulkan is a low-overhead, cross-platform 3D graphics and compute API released by the Khronos Group in 2016 as the explicit successor to OpenGL. Vulkan exposes GPU command buffers, memory management, and synchronization primitives directly to the application, allowing far better multi-core scaling and lower CPU overhead than OpenGL — at the cost of significantly more complex application code. Vulkan is supported on Windows, Linux, Android, macOS (via MoltenVK), and most modern GPUs.
Why it matters
Vulkan is what real-time CAD viewers, simulation visualization, and AR/VR design tools migrate to when OpenGL stops scaling on multi-core CPUs. It's the foundation for next-generation engineering visualization — including AI-assisted geometry inspection, real-time NURBS tessellation on consumer GPUs, and the kind of cloud-streamed CAD that requires extracting every microsecond from the render pipeline. The Vulkan/DirectX 12 generation is also the API tier where machine-learning surfacing first becomes practical inside the rendering loop.
