Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

If you've been paying attention to the launches of the new generation of game consoles, you've probably heard talk of ray tracing. Ray tracing is a rendering technique for photorealistic graphics by ...

Before diving into ray tracing ("RT" for short), let's first take a look at how illumination works in the real world. From the micro-perspective, the surface of an object illuminated by a ray of light ...

Real-time path tracing, the next stage of game rendering, is on the horizon, Nvidia says. But wait--didn't RTX just get here? So what is path tracing, how is it different from ray tracing, and why ...

Ray tracing and path tracing sound similar — and technically, they are. Both methods simulate how light travels in a 3D environment, but the way they work and the results they produce are completely ...
