Ray Marcher

What Is This?
A little ray marching tech demo! It works similar to a ray tracer, but uses signed distance functions to determine if a ray hits an object. The benefit of doing it this way is that you can create some cool effects by modifying how you combine or blend these functions. My favorite is Taffy + X-Ray shading :)
