This implementation uses multi-threading, ranges, and [imgui](https://github.com/ocornut/imgui) to provide an interactive rendering experience. +UI controls include: + +* Field of view +* CPU thread/worker count +* XYZ camera position +* IJK camera "look at" position +* Samples count to control render quality +* Global shade control for "day" or "night" rendering +* "balls" window: Add or remove spheres and set each sphere's material, size, and position + +The UI also does low-quality "live" rendering as settings are changed; click "recalculate" to render in high-quality. The visible render can be exported as a PNG image to the current directory. + + + +## Build instructions + +1. Download imgui submodule via `git submodule`. +2. Have GCC, GNU Make, and SDL2 installed. +3. Run 'make'. + +The final program binary is called `main`. |
