Looking at the ANARI spec and SDK it looks pretty much like a typical C API to me, implementing an old-school scene-graph system. What am I missing - e.g. what makes it specifically well suited for non-C languages? :)

If anything it looks more like an admission by Khronos that Vulkan wasn't such a great idea (but a 3D API that's based on scene graphs isn't either, so I'm not sure what's so great about ANARI tbh).
