Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality.
For example, path tracing struggles with caustics from a point light source because it is unlikely to randomly generate the exact path needed for accurate reflection. [4] On the other hand, progressive photon mapping (PPM), a biased technique, handles caustics effectively. Although biased, PPM is consistent, meaning that as the number of ...
Tracing is the act of copying an image or work of art by drawing over its lines, especially through the use of transparent overlays. [ 1 ] Tracing can provide a way for a person to develop their artistic skills for example when it comes to learning anatomy.
Optical ray tracing describes a method for producing visual images constructed in 3-D computer graphics environments, with more photorealism than either ray casting or scanline rendering techniques. It works by tracing a path from an imaginary eye through each pixel in a virtual screen, and calculating the color of the object visible through it.
Autodesk Arnold (also known as simply Arnold) is a computer program for rendering three-dimensional, computer-generated scenes using unbiased, physically-based, Monte Carlo path tracing techniques. Created in Spain by Marcos Fajardo, it was later co-developed by his company Solid Angle SL (now owned by Autodesk ) and Sony Pictures Imageworks .
Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. [1] This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire ...

Bricks rendered using PBR. Even though this is a rough, opaque surface, more than just diffuse light is reflected from the brighter side of the material, creating small highlights, because "everything is shiny" in the physically-based rendering model of the real world.
