-# Rendering in rust
-
-This is a (not finished) ray tracer written in rust.
-It is based on the book serie [Ray Tracing In One Weekend](https://raytracing.github.io/) and [Physics Based Rendering](http://www.pbr-book.org/).
-
-This rust version is my third implementation, the previous being:
-
-
-- [Raytracing in c](https://git.jtle.dk/raytrace/about/)
-    This is the one which gives the best results,
-    however as my ambitions for the project grew as did my requirement for more language features.
-- [Pathtracing in c++](https://github.com/jbjjbjjbj/rendering/tree/old_master)
-I never really finished it before changing to rust.
-    However it had a really cool qt gui, updating as samples were added.
-
-## Rendered image
-
-![render](https://raw.githubusercontent.com/jbjjbjjbj/rendering/rendered/generated.png)
-
-## Goals
-
-- [X] Render collection of circles outside, with blurry background
-- [ ] Render [Cornell box](https://en.wikipedia.org/wiki/Cornell_box)
-- [ ] Render [Utah teapot](https://en.wikipedia.org/wiki/Utah_teapot)
-- [ ] Render [Stanford dragon](https://en.wikipedia.org/wiki/Stanford_dragon)
