This update came a bit late due to some personal problems, but I managed to get it finished.

The Raymarching toolkit is ready and now available on the
Unity asset store.
It was named FERM for Fast Easy RayMarching. In particular I made 3 videos to showcase and explain the strengths of the toolkit.

The first video is a general trailer showing a andful of scenes rendered with FERM.

The second video showcases the audioreaction scripting.

And an example/tutorial video showing how you can create a specific effect.

A short explanation of the showcased scenes:

• Title scene:
  The background is the SkyFractals scene. In the foreground there is a representation of the FERM logo, the F consists of smoothly mixed boxes, the E is a sphere with 2 boxes differenced away, the R is intersected with a rotating mandelbulb fractal and finnaly the M is a tilted capsule shape that is recursively scaled and mirrored.
• MandelZoo:
  This is just an animated zoom in of the Mandelbulb fractal. The fractal is shaded with a gradient that depends on the radial coordinate. This gradient slowly shifts over time.
• FERM rollaball:
  This is just a simple assembly of boxes, unioned and differenced to the point of making a functional rollaball setup. This result is repeated infinitely and bent to give the final effect. This is the only example using standard shading, with a basic gold scheme.
• AudioReact soundscape:
  This scene is set up with a sierpinski fractal that deforms over time. This fractal is revolved around its primary axis to yield ring formations laid out in a cone. By rotating the source fractal, these rings grow, shrink, move, dissapear and appear. This fractal is repeated in the x- and z-axis directions and mixed smoothly with an infinite plane. This plane is also deformed by a 2D sine wave. The parameters of this scene are subject to audioreact input, which makes it respond to the music.
• SkyFractals:
  This is the same mirror box fractal shown in the tutorial video. In this case, this fractal is stretched out infinitely using the modulo operator (which leaves a gap in the cardinal directions). This result is also slightly bent to hide infinite cubic grid artefacts. The shading is just a single color, only the regular occlusion effect is inverted: more 'occluded' surfaces are colored brightly, while the nearby surfaces are colored black.
