What is Ray Tracing?

Ray tracing is a graphics rendering method that uses an algorithm to calculate where light and shadow should be in a video game.

For example, when you're looking at a mug or cup, light bounces off the mug straight into your eyes, and your brain perceives the object sitting in front of you as a mug. And when you move your eyes away from the mug to find a light source in your room. is ray tracing.

In today's 3D video games, ray tracing algorithms start with the player's perspective and are set to track, identify, and map the light, color, and shadow of multiple objects on the screen. As a result, the graphics produced through ray tracing are smoother at the edges and more realistic.

Before Using Ray Tracing

Before Using Ray Tracing

If you want to know what motion pictures were like before ray tracing, just take a look at video games made in the early 2000s, and compare them to AAA video game titles on the market today. AAA video games are games that have an A score in graphics, gameplay quality, and of course sales results.

Older computer graphics used a method called rasterization, in which concepts and plots of 3D light sources were converted to 2D surfaces. 3D polygons were translated into 2D pixels, and this didn't always work well. Also, old computers aren't fast enough to keep up with the intensity of video games.

How Does Ray Tracing Work?

How Ray Tracing Works

Ray tracing sounds simple and interesting as a concept, but it is not an easy technique. So, how does ray tracing work?

Ray tracing performs a process called “denoising”, where the algorithm, starting from your camera's point of view, tracks and shows the most important shadows of light and shadow. It also uses machine learning to form photorealistic images. So, the brighter the scene in a video game, the higher the graphics quality, and the higher the quality, the more expensive it is.

When is Ray Tracing Used?

Ray tracing is used almost everywhere in video games, but especially in cut scenes. Have you ever noticed why your characters look more lively and sophisticated during video game cutting scenes? That's when ray tracing kicks in. The controls of the 2019 hit AAA title are the best examples of successful ray tracing in video games.

Outside of video games, ray tracing is also used in many industries. In architecture, ray tracing is embedded in application software for 3D modeling of a building. This makes the architect's imagination of the building design more realistic than hand-drawn concept sketches, and the modeling lighting is more accurate.

Who was the first game developer to use Ray Tracing?

After acquiring ray tracing company RayScale in 2008, Nvidia became the first in the industry to commercially launch ray tracing technology. In 2018, it introduced its GeForce RTX series graphics cards to consumers. Since then, leading game developers have joined the game. ray tracing, one by one and the first game to support ray tracing was Battlefield V.

In 2019, Epic Games and Utility Technologies announced that their signature hardware engine now offers native support for ray tracing. In 2018, Microsoft integrated ray tracing into DirectX 12, its main multimedia and game programming software for the Xbox One. Early 2020 , the tech giant launched DirectX 12 Ultimate, an upgrade to DirectX 12.


So what is ray tracing? Ray tracing is a technology that creates an image by following the direction of a simulated light. In essence, ray tracing will provide a high-quality visual experience. Ray tracing in video games is still in its early stages, but its entry into the market marks a promising future for the industry.
