Real-Time Ray Tracing Demo
An anecdotal observation: there seem to be many ray tracing-related articles and ShowHNs that make the  front page. For someone who isn&#x27;t in the computer graphics space, what&#x27;s the importance of improving existing ray tracers or the novelty in writing one&#x27;s own? Is writing one a particularly challenging thing to do? Is improving existing ray tracers the equivalent of chip manufacturers increasing CPU performance in the chip world? Just trying to understand this a bit better.
