Wow! Sixteen reflective spheres above a plane!

Seriously: I am not so sure anymore that povray is a good choice for 4D
visualization. The problem is that all these reflections make your object
look like it really belongs in 3D space. In the old days when wireframes
were "just lines" it was easier to acknowledge that what you see is only
a representation of something else. Maybe it would help to make the edges
thinner and the vertices smaller. Maybe I'm just missing the animation.

Anyway: Beautiful image. And don't remove the red spots from the floor.
The image would look rather pale without them.

Very nice textures !

Are you going to upload the amnimation somewhere on the web ?
The fourth dimension is always soooo fascinating ;)

I don't know - are *you* going to download 27MB? ;-)

I've downloaded far bigger .avi's from the Planetside forums...

I think the biggest was about 160Mb...

So yes, there are idiots out there who would download it and kill your 
bandwidth if you were hosting from home :D

Jamie.

Oh, wait... my webspace is only 10MB! Well, that's that I guess...

Well, maybe not - I could *fit* it into (say) 9MB without too much loss 
of quality...

Alternatively, maybe I should just post to povray.binaries.scenefiles 
(Although it did take 3 days and 3 nights to render! LOL)

No checkers tho. ;-)

Well... the trouble with a true wireframe is that it can be just a mass 
of lines, and it's hard to figure out (no pun!) what you're actually 
supposed to be seeing.

A full render like this makes it easier to see the 3D form. Attempting 
to see a 4D form is probably impossible. Strictly you probably don't 
*need* the reflections, but I feel it helps you place things in 3D.

Well, I'm glad you like it. :-) I do too!

Yeah... haven't got them to look quite right yet... I only recently got 
into texture layering in POV-Ray - fun, isn't it? ;-)

I agree -- I tried to redo some of Escher's stuff with spectacular 
failure. Visual tricks are very hard to do when the object properties 
are so objectively defined.

You don't get too more objectively defined than LEGO.

I baffle at the frequency of how often I am humbled by the brilliance of 
others.
