This is a GUI frontend for the PSRayTracing implementation of the "Ray Tracing in One Weekend" books by Peter Shirley (and others). Which renders the images in the book faster than the reference code, but also offers other features (e.g. threading, render progress, toggle-able and more). The source code for this program, as well as a report auditing all of the changes/improvements, is freely available at: https://github.com/define-private-public/PSRayTracing

The clearest difference is update cadence: Lithium Cloud IoT at every 3 weeks against PSRayTracing's every 30 months. Lithium Cloud IoT also leads on iOS requirement (12.0 vs 17). On price, ads, in-app purchases and device support there is nothing between them.
