Parametric Rendering

[Zi7ar21]

Currently, the scene is hard coded into the path-tracer and it needs to be rebuilt every time it is modified but it would be better if it instead loaded from a file so that the path-tracer can render any scene from a file made with a custom format, like how POV-Ray works so that the path-tracer can render scenes without needing to be re-built.

Also falling under this issue, it would be awesome to be able to load and render meshes. However, this is something in the future as currently ray-marching a bunch of polygons would be slow unless there is a system of accelerating this, such as ray-tracing's BVH mechanics.
