PSRayTracing vs Shader Playground

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

Shader Playground is a powerful real-time shader editor built for iPhone and iPad. Write Metal fragment shaders, see results instantly at 60 FPS, and export your creations as images or videos. REAL-TIME PREVIEW Write code and watch your shader come alive instantly. The live preview renders at 60 FPS with full support for standard uniforms: iTime, iResolution, iMouse, and iFrame. SHADER EDITOR WITH SYNTAX HIGHLIGHTING A dedicated code editor with Metal Shading Language syntax highlighting, monospace font, and smart keyboard tools — designed for comfortable coding on mobile. BUILT-IN SHADER LIBRARY Get started immediately with 10 ready-to-use shaders including plasma, Mandelbrot fractals, raymarched 3D scenes, Voronoi patterns, ocean waves, and more. Learn by exploring and modifying working examples. MULTI-PASS RENDERING Build complex effects with up to four buffer passes. Chain textures between passes to create feedback loops, blur effects, and advanced post-processing pipelines. TOUCH INPUT Map touch and drag gestures directly to shader uniforms. Create interactive visual experiences that respond to your fingertips. SAVE & LOAD PROJECTS Save your shaders locally and pick up where you left off. Build your personal library of custom effects. EXPORT Capture the perfect frame as a PNG image or render smooth MP4 videos at custom resolution, duration, and frame rate. Save directly to your Camera Roll or share anywhere. Whether you're a graphics programmer, creative coder, student learning GPU programming, or a visual artist exploring generative art — Shader Playground gives you a complete Metal shader development environment in your pocket.
