## Impilmented Topics

 - Objects:  

   - Sphere

   - Box

     - Rectangles (axis-aligned)

 - Materials:  

   - Diffuse (lambertian)

   - Metal

   - Dielectrics

   - Textures

     - Perlin Noise

     - Image Mapping

   - Diffuse Light

 - Camera

   - Orientation

   - Defocus blur (depth of field)

   - Motion Blur

 - Optimization

   - Bounding Volume Hierarchy (BVH)

   - Multithreading

 

## Output

Output is in .ppm format. Right now, to get an output image, run build. The exe will output `image.ppm`.  

To change the quality of the image, change `samples_per_pixel` or `image_width`.  

Output from *random_scene*  

![sampleRender2](Images/sampleRender2.png)  

It is intresting to note that glass spheres do not cast shadows. This is physically correct.

### To-Do

 - ***Lights***

 - Rectangles

 - Volumes
