How a new technology is allowing to update the graphics of a video game from 20 years ago

Ray tracing has amply demonstrated its ability to bring greater photorealism to various video games, but there is a technology that goes even further. It’s called ‘path tracing’ it’s a kind of ‘super vitamin ray tracing’.

An AMD engineer named Dihara Wijetunga has wanted to demonstrate his impact in a video game, but not just any one. His idea was to create ‘Wolf PT’, a version of the mythical ‘Return to Castle Wolfenstein’ that uses this technology and that thanks to it offers a truly fantastic fidelity in the treatment of lights and shadows.

‘Return to Castle Wolfenstein’ was already a spectacular title when it was released in 2001. Developed by id Software with the Id Tech 3 engine and published by Activision, this engineer I wanted to take those scenes even further thanks to the ‘Path Tracing’ or ‘path tracing’.

With the ray tracing, those rays are sent into a scene from a virtual viewfinder. As soon as these hit a solid object, more rays are sent in the direction of each light source in the scene, which is followed by the calculation of intensity or reflections.

With path tracing, hundreds or even thousands of rays are sent into the scene to calculate each pixel, but those rays are traced “along” the scene, no matter how many times they bounce. That involves a much higher computational effort than ray tracing already requires.

The development of this special version of the video game —there are similar projects like that special version of Minecraft with RT— is still in an early phase, but Wijetunga wanted to share several images in which you can see the impact that this technique has in various scenes of the video game.

Shading is more realistic and so is the lightingwhich is applied much more faithfully to what the light sources in each scene pose.

These are the reasons why image reconstruction technology is the best thing that has happened to graphics cards and consoles

In the image with the rays crossing the room, for example, they didn’t seem to have any influence on the finish of the original scene: in ‘Wolf PT’ they “fill” the whole room with that blue light.

is there any effect harmful in the form of noise, but even if it does occur, it may fade as more and more ray “paths” build up to produce a clean image. It will be necessary to see if ‘Wolf PT’ ends up being available to the public, but of course this technique seems to show that even old titles can win many points visually.
