Today, beam tracking is the hottest technology in game graphics. Nvidia’s RTX graphics card is in the second generation and the competitor AMD has hooked up with its own variant in the Radeon 6000 family.

But radiation tracking is just the beginning. In the future, Nvidia wants to switch to a more advanced form called path tracing, writes Hot Hardware.

Track tracking has long been used in 3D rendering for film and television, and involves a large number of “light rays” being sent from each pixel in the image and allowed to be reflected and refracted until they reach a light source. Then the intensity and color of the light are calculated from all these reflections and refractions, and the final color of the pixels is calculated as an average of all these rays.

This makes the technology many times more computationally intensive than ordinary radiation tracking, and Nvidia says that it will be a long time before there are graphics cards and games that make full use of it.

Nvidia has produced a demo showing a tiger walking along a muddy beach. The stage has three billion triangles in geometry and the tiger’s fur consists of 3.5 million animated hairs. The light rays can bounce up to 30 times.

To speed up calculations and get closer to real-time rendering with track tracking, Nvidia’s developers have worked hard on noise reduction.

If you are curious, you can download one Powerpoint presentation (at 660 megabytes) from Nvidia with more sample videos and images.
