WHAT IS RAY TRACING?

Traditional 3D rendering has relied on rasterisation, where objects are built using a mesh of triangles and then shaded to create their appearance. While effective, rasterisation can only approximate how light behaves in the real world.

Ray tracing is different.

Inspired by how light works in nature, ray tracing simulates the path of photons as they bounce around a scene—from the light source to the viewer’s eye. As light interacts with surfaces, it’s blocked, reflected, or refracted, even by off-screen objects. This creates realistic shadows, reflections and lighting effects.

The result? More life-like images and a simpler, more intuitive lighting process for developers and content creators.

FREQUENTLY ASKED QUESTIONS

Ray tracing is a technique used in computer graphics to create highly realistic images by simulating the way that light interacts with objects in a scene. The process of ray tracing can be broken down into the following steps:

Casting rays: The first step in ray tracing is to cast rays from the camera through each pixel in the image plane and into the scene. These rays simulate the paths that light would take from the objects in the scene to the camera.

Intersecting with objects: As the rays travel through the scene, they may intersect with objects such as walls, floors, and other objects. When this happens, the ray is reflected, refracted, or absorbed by the object based on its material properties and the angle of incidence of the ray.

Calculating lighting: As the rays travel through the scene, they may also intersect with light sources such as lamps or the sun. When this happens, the colour and intensity of the light is calculated and added to the final colour of the pixel.

Combining colours: The colours of each pixel are calculated based on the materials the rays touch, the angles at which they touch them and the properties of the lights they finally intersect with.

Many modern video games use ray tracing to create highly realistic lighting and shadows. Ray tracing allows game developers to simulate the way that light interacts with objects in a scene, which can make virtual environments feel more immersive and lifelike.

Some examples of games that use ray tracing include:

  • Cyberpunk 2077: This open-world action RPG from CD Projekt Red uses ray tracing to create highly realistic reflections, shadows, and global illumination.
  • Control: This third-person action game from Remedy Entertainment uses ray tracing to create realistic reflections, shadows, and global illumination, as well as to simulate the way that light bounces off of surfaces.
  • Minecraft: The popular sandbox game from Mojang uses ray tracing to create highly realistic lighting and shadows, as well as to add reflections and other visual effects.
  • Call of Duty: Modern Warfare: This first-person shooter from Infinity Ward uses ray tracing to create realistic shadows, ambient occlusion, and reflections.
  • Battlefield V: This first-person shooter from DICE uses ray tracing to create realistic reflections, ambient occlusion, and global illumination.

Ray tracing can also be used to accelerate the game development pipeline. The technology makes it quick and easy for artists to visualise the impact of changing the location, brightness, size or colour of a light source.

Rasterization is a technique where a scene is rendered by projecting 3D objects onto a 2D screen, and then filling in the pixels with colours based on the object’s surface properties and lighting conditions. Rasterization is an efficient technique and well-suited for real-time applications such as video games.

On the other hand, ray tracing is a technique that simulates the behaviour of light as it interacts with objects in a 3D scene. In ray tracing, rays are traced from the camera through the scene, and the colours of the pixels are determined based on the objects and lights with which the rays interact. Ray tracing produces highly realistic images with accurate lighting and shadows, but it is computationally intensive and requires either a lot of processing power or specialist hardware.

One key difference between rasterization and ray tracing is how they handle reflections and shadows. Rasterization often uses simplified techniques to simulate reflections and shadows, which can result in less realistic images. Ray tracing, on the other hand, simulates the behaviour of light in a more accurate way, which can lead to more realistic reflections and shadows.

Rasterization is a fast and efficient technique for rendering images in real-time, while ray tracing is a more computationally intensive technique that produces highly realistic images with accurate lighting and shadows. To find out more checkout our blog ray tracing vs rasterization
