High!
Experimenting with worlds covering a large range of orders of magnitude
(for example the Solar System with 1 unit = 1 km), I pretty soon
discovered the limits of PoV-Ray... nothing smaller than 0.0001 or
larger/further away than 10,000,000 units is rendered correctly. I
remember having brought up that issue years ago in
comp.graphics.rendering.raytracing, back then I was told of the ominous
"epsilon". What is this "epsilon" precisely?
Is there a not too complicated way to modify the range of orders of
magnitude to, let's say 1e-8 to 1e13, so that everything from amoeba to
Pluto's orbit can be rendered within one scene, by hacking the code?
See you in Khyberspace!
