###Usage

- First compile the program using:

```

c++ -o rtracer -O3 -Wall main.cpp

```

- Next, run the executable. Doing so, generates a [PPM](http://www.fileinfo.com/extension/ppm) image of the scene generated:

```

./rtracer

```

- Finally open the scene image created using a PPM Viewer

    - ToyViewer/Photoshop for Mac

    - GIMP for Linux

###Todo

- Anti-aliasing

- Object refractions
