Real-Time Ray Tracing

Discussions revolve around the feasibility, hardware acceleration, and implementation of real-time ray tracing in games and graphics rendering, often comparing it to rasterization and debating its current limitations and future potential.

Real-time raytracing would benefit so much from that.

Very few games have implemented raytracing

Ok, then where's the ray tracing? ;-)

Why is real time ray-tracing infeasible?

make3 Aug 14, 2018 View on HN

afaik raytracing is not worse if given the time

ilaksh Jun 17, 2013 View on HN

Ray tracing is the way forward.

That kinda sounds like raytracing.

Games don't do full raytracing like blender or maya. Their raytracing works hand to hand with rasterization.

Ray tracing is done in shaders these days. Doesn't make it cheap.

Hardware accelerated ray tracing?
