I want to include hybrid rendering for shadows, but im afraid iOS devices can handle the workload. They didn't mention anything on the video about iOS performance
Hybrid rendering recommended for iOS?
Hi masaldana2,
You can take advantage of the Metal Raytracing API on iOS to implement hybrid rendering techniques. The biggest consideration for performance is going to be the number of rays you trace to produce your frame.
If you need to trace rays in realtime, the fewer rays you need to trace, the better your performance will be. Temporal denoising techniques allow taking images generated by limited ray counts, for example tracing fewer than 1 ray per pixel, and reconstructing and image that looks correct (not noisy).
This is a complex topic and is currently an area under significant active research in the industry. One session I can recommend as an introduction to the problem space is "It Just Works: Ray-Traced Reflections in 'Battlefield V'" from the 2019 Game Developers Conference.
