# Vanrijn
|
|
|
|
This project is very much a work-in-progress and at this point.
|
|
|
|
Vanrijn is (or at least will be) a [physically based](https://en.wikipedia.org/wiki/Physically_based_rendering)
|
|
[ray tracer](https://en.wikipedia.org/wiki/Ray_tracing_(graphics)). Many thanks to the
|
|
authors of the book
|
|
["Physically Based Rendering: From Theory to Implementation](https://www.pbrt.org/) from
|
|
which many of the algorithms used here are taken. This is, however _not_ a Rust port of
|
|
the C++ PBRT rederer described in that book.
|
|
|
|
This crate is structured as a library; main.rs is just a glorified test harness which
|
|
shows an example of using the library to render a scene. It uses SDL2 to display the
|
|
rendered image.
|
|
|
|
On Ubuntu 19.04, if you have the libsdl2-dev package installed you
|
|
should be able to run `cargo run --release -- --size 800 600` and see
|
|
a window with a test scene rendered into it. In theory it should work
|
|
on any platform with SDL2 installed but I've only tested it on Ubuntu
|
|
Linux.
