Its raytracing
Even Nvidia is using approximations to accelerate the process compared to "true ray tracing" or we wouldn't even be having "real-time" RTX in games even now.
You made your thread on ray tracing, not
this solution or the ray tracing that is hitting triangles rather than mesh. I don't give a fuck, devs don't give a fuck, it's ray tracing. Teardown is full blown software ray tracing too. Crytek's solution too.
Solutions ! Gosh, imagine that, taking ray tracing maths you want and implement them how you want on a math focused machine (computers). Incredible.
