For Jesse, article about raytracing and stuff

[DarkBeam]

I think this can be very helpful, also a section about blobs.

Fresnel part is for refractive materials like glass

[Jesse]

Nice article, the fresnel stuff is simple from the math, so this is not the current problem 

The DEcombinate with overlap is shabby, not blobby enough... i guess (is this the point  )

But I like the nonlinear one. The linear probably needs a fixup?

Jess...are you actually contimplating adding a materials choice to the program??? Perhaps as a post process? From there materials could possibly be added by color selection

That would be pretty wild, but way ambitious

Then it's ok, the linear is just an extra option, maybe used less often.  If i find a more interesting one i might change it in the future.

I could imagine something in this direction, but you have always keep in mind that the rendering is a bit different than in most 3d programs that renders on meshes.
So it is not always easy to fix some textures on certain parts, for example.

But some improvements are surely possible, when times come...
