With the launch of the RTX 20 NVIDIA, the RayBetter known as Ray Tracing, a technology that is in most triple games that have arrived on the market since then and which allows you to offer realistic images. But much earlier, there was already the Path tracingAnother technique which, such as tracing rays, simulates the behavior of light. The two things do more or less the same but differently, what would you say better?
Although fundamentally, their mission is the same, the two do not work in the same way or offer the same graphic quality. If you want to know how to track the rays and tracing the paths work and what are the different, we invite you to continue reading.
What is the layout of the rays
The tracing of the rays is a razorisation technique which is responsible for the launch of the rays of light which follows an established path from the camera to the scene to determine how the content is displayed. It simulates direct lighting, reflexes and refractions depending on the camera's rays to objects.
What is path tracing
For its part, tracing the path is a more advanced way to track the rays than to simulate real physics of light after several rays by pixel. Use statistical methods to disperse light through a scene to offer global lighting. By generating a greater number of random -dispersed rays, it provides much more precise indirect lighting effects and a more realistic light of light.
What is the best?
Using statistical methods, the time required to make content with path tracing is much higher than with the tracing of the shelves because it generates a greater number of rays and needs a greater number of calculation resources. This is one of the reasons why it was created, because, although its operation is not as precise and faithful to reality as track tracing, fewer operations are necessary to generate the content.
As we commented above, the light effects that are generated by tracing the path with much more realistic than those obtained by tracing the rays. By having a more realistic behavior, the light of the distribution is distributed more uniformly through the scene eliminating the dark areas.
Due to the complex functioning of tracing the paths, the number of games that offer management to this is much lower than that which we can find compatible with the tracing of the rays. Alan Wake 2 Y Cyberpunk 2077 These are some of the triple titles to which they have chosen to implement the support for tracing the paths. Microsoft has also implemented the management of paths tracing Minecraft With spectacular results.
Although the tracing of the rays has become the most used technology to simulate light behavior in video games because it requires fewer operations to carry out it, the best result is offered by the road race by offering a more realistic result of global lighting, it does not try to imitate it as tracing of the rays.
