change to 0.0 older versions of GLSL don't do implicit casting

Argh, sorry. Keep forgetting about this, as I'm testing under OpenGL 4.5 and Unity, but not WebGL.

All good! I'm sorry to bring it up later. I will do my part better and watch for those running against OpenGL ES 2.0 (you can't get older than that : )

Sounds good! Just PRed a fix.

Added AOV (Arbitrary Output Variables) output support to the Raymarching engine.
These additional buffers are very useful for post-processing passes. And the good news: they come almost for free, as raymarching already provides us with this data!
We now have:
Color
Alpha
Eye Depth
World Position
World Normals
And finally, to illustrate, some DOF fun using the Eye Depth AOV and Lygia's sample/dof
