Greetings all
This is an unexpectedly successful bit of tinkering; didn't start as a serious
project but I thought I'd share today's results. It's my take on Escher's
'Tetrahedral Planetoid' - mostly procedurally generated, using spherical shells
differenced with cones centred on tetrahedron faces as a basis, and some trig
and transform jiggery-pokery to place simple buildings.
It's not finished yet - I'm considering some more details like ships or islands,
some greenery, towers or masts on the vertices, and I think I can make bridges
under the low points on the edges to join up the water pools.
Any comments or suggestions welcome!
Bill

I wish I could tinker like that. Well done.
Cheers
Ton.

That's some pretty fancy jiggery-pokery there, my friend.
Maybe your island could be like the little icosahedron in the the Magic 8-Ball -
sinking from one pool and surfacing in another :D
Also, a night scene would be pretty cool.
Does this orbit a trefoil sun? ;)
"The groundhog says there's a 1-in-4 chance of an early Spring this year..."
What about an Earth-Air-Fire-Water theme instead of 4 water pools? Mountain,
mist, volcano/fiery sinkhole, pool....

How about some cloud cover?
I ran across
http://abx.art.pl/pov/patches/f_triangle.php
and that might be adaptable to a tetrahedral shape to make cloud media...

He builds the entire Titanic from scratch, and he wishes he "could tinker like
that."
:D :D :D
You have more skill than you give yourself credit for.

Wow, that is great!
Can't think of any suggestions, other than more detail: people,
vehicles, laundry, boats, etc.

A notable image.
What kind of physical phenomena will there be on such a planet? Winds
(and waves), bizarre clouds, ...
;-)

Aaah! A return to the tetrahedral universe!

Thanks!
And as pointed out, your own adventures in CSG are not to be sniffed at! It's
refreshing to see old-school POV-Ray techniques used to such detail. I only just
caught up with your Titanic progress, sorry to hear you had a setback. As Thomas
said, maybe you'll feel like revisiting it someday.

Aha, yes could be good. I'd need many lights though, which could be problematic.
Moonlight perhaps.

I'm thinking a water sphere linked under the edges, maybe with small rocky
island at the centres of each.
As as to cloud cover, I wondered about that, but I'm reluctant to embark upon
extensive media odysseys... if I can't do something cunning with regular
transparent textures I might not bother!
