# raytracer
|
|
|
|
An implementation of raytracing in modern C++, based on code from the [Ray Tracing in One Weekend](https://raytracing.github.io/) book series. 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.
