<h1>What is Ray Tracing?</h1>
<p>Generally speaking, ray tracing is a "physically accurate" simulation of how light interacts with different surfaces,
volumes and a camera. At the core of ray tracing are the rendering equation and all of the mathimatical equations
that describe ray-entity intersection and interactions like diffusion, reflection, and refraction.</p>
<!-- <h2>How does it Work?</h2>
<p>Before any calculations can be done, a "scene" is required which contains the following items:</p>
<ul>
<li>A camera.</li>
<li>Any number of objects.</li>
<li>A list of material definitions.</li>
</ul> -->

<h1>Limitations</h1>
<p>While this demo may look quite incredible, it is NOT completely physically accurate because it doesn't simulate the wave properties of light. Some missing features include:</p>
<ul>
<li><a href="https://en.wikipedia.org/wiki/Diffraction" target="_blank">Diffraction</a></li>
<li><a href="https://en.wikipedia.org/wiki/Dispersion_(optics)" target="_blank">Dispersion</a></li>
<li><a href="https://en.wikipedia.org/wiki/Polarization_(physics)" target="_blank">Polarization</a></li>
<li><a href="https://en.wikipedia.org/wiki/Phosphorescence" target="_blank">Phosphorescence</a></li>
<li><a href="https://en.wikipedia.org/wiki/Wave_interference" target="_blank">Interference</a></li>
<li><a href="https://en.wikipedia.org/wiki/Fluorescence" target="_blank">Flourescence</a> (although this is easy to add)</li>
<li><a href="https://en.wikipedia.org/wiki/Doppler_effect" target="_blank">The Doplar Effect</a> (although not super applicable)</li>
</ul>
<p>Nevertheless, it does support the major and most noticable features of light interaction, lncluding:</p>
<ul>
<li>Diffusion - light scattering on rough surfaces</li>
<li>[Specular] Reflection - perfect light reflection</li>
<li>Refraction - light bending/splitting when it passes between different refraction indices</li>
</ul>
<p>Another major limitation of this demo is that it can only render a limited number of surfaces. More professional rendering applications allow for a multitude of shapes/volumes to be used.</p>

<h1>Further Learning</h1>
<p>Why stop here? <a href="https://en.wikipedia.org/wiki/Ray_tracing_(graphics)" target="_blank">Wikipedia</a> has much more information than I can put on this page! Also check out the <a href="credits.html">credits page</a> for other resources used in the making of this project.</p>
