This project implements a raytracer with Blinn-Phong illumination implemented.
The primary formula that is used by this implementation is:

$$
I_{\lambda} = k_a O_{d\lambda} +
  \sum_{i=1}^{n_\textrm{lights}} \left(
    IL_{i\lambda} \left[
      k_d O_{d\lambda} \textrm{max} \{
        % 0, \overrightarrow{N} \middot \vec{L_i}
      \}
    \right]
  \right)
$$
