Path tracing is a rendering technique that simulates how light bounces around a scene to produce physically realistic images, usually computed on a GPU. It produces the most convincing interior and exterior renders, including soft shadows and reflected light. Faster GPUs have made path-traced renders practical inside everyday design tools.

## Why does path tracing matter for architects, engineers and contractors in India?

It produces the most convincing interior and exterior renders, including soft shadows and reflected light. Faster GPUs have made path-traced renders practical inside everyday design tools.

## What is an example of path tracing?

An interior designer renders a living room with path tracing so sunlight bouncing off a light floor brightens the ceiling realistically.
