What’s This Ray Tracing Stuff?In case the term Ray Tracing is news to you, here’s a quick explanation. Ray tracing is the premier technique for rendering photorealistic graphics. It’s used to make CG effects and films. Its very rough on computing power and can’t be done in real time, which is what a video game would need. In traditional game graphics the way light behaves is faked using many tricks and shortcuts developed over the years. Modern traditional game graphics looks superb, but it’s still a long way from being photorealistic.
Ray tracing does not take shortcuts. It simulates the path of light rays bouncing through a scene, providing a final result thats pretty much photoreal.
Why is Ray Tracing so Important for VR?It has to be seen to be believed, but RT graphics represent a huge jump in realism. It turns simpler titles like Minecraft and Quake 2 into something that looks like the real world, but as a sort of diorama. It gives the brain what it expects to see in the real world and removes a significant layer that prevents the VR illusion from being complete.
Virtual reality is being used in health care. It allows medical students to practice dangerous procedures and gain experience without actually operating on a human. It can also help surgeons determine the best point of entry for surgeries.
Seriously, just look at thus Minecraft RTX demo.
If your jaw doesn’t drop to the floor, check your pulse.
Why We Can’t Have Ray Tracing in VR Just Yet?
The short answer is simply poor performance.
