No you don’t know me! I just stumbled across something while furkling around on the internet…

Curious about the title of this thread? You should be. This is a little site I’ve developed and I’ll update it as frequently as I can. http://www.angelfire.com/art/hobbies. Mengermania! It’s a site devoted to something I’ve been working on for the past 10 weeks or so. Well now it’s 11 I think. I’ve lost track! Check it out. Tell me what you think. Am I too obsessed?

I started making a Menger sponge in Bryce last night – got to the point where duplicating four sub-groups was taking around three hours or more… decided to wait on finishing the last level of the sponge 'til after I can archive some stuff to CD today…

Those are cool! I’ll have to see if I can make one in Blender! Although, without a Boolean kin 1000 d of operation in Blender, it will be closer to doing it by hand than in Bryce…

you don’t need booleans at all, just cubes.8 cubes around the bottom (middle one missing). same thing for the top. then, fill in the sides with ‘corners only.’ that becomes your basic unit. group it, then use that group as if it was a plain cube and construct the same sort of object… 8 groups around the bottom, same thing for the top, fill in the sides with groups at the corners only… group this thing again… repeat… 'til your machine bogs down trying to duplicate the groups of cubes…

lol… I’ve done that, more or less: make a plane, extrude it until it’s in a 3x3 grid, extrude that until it’s a 3x3x3 cube, and delete/fill in the necessary faces, making heavy use of the SNAP menu so they are all exactly perpendicular to each other, then duplicate them, snap them to the grid, join them as one object (uses less memory) and continue, as calyxa said, until your machine is too slow to move around in (duplicating hasn’t been a problem so far)… I’m on level three and slow, but manageable (I’ve made indoor building scenes that slowed it more than this). I’ll post a picture of it as soon as I get it as big as it will comfortably go.

Wow. I didn’t think I would make people interested in making this thing.
What’s the equation?..ummmmm…duhh…
I have no idea!
Calyxa, there is an easier way to get a level 3 without making your computer crash in Bryce, but making a level 4 makes your computer crash no matter which way you do it!

I’ve made a level 4 in Blender . But I can’t make a higher level, because I got it to work by placing each level 3 cube in a separate layer, and I’m out of layers! Now I just need to give it a decent texture(s) and render it. I’ve only had illegal operation errors two or three times. But it is very very slow to move the view around, even with each in a separate level!

Well, I sort of got it to work. See here http://www.geocities.com/rivenwanderer/fractalsponge.html. I’ll probably delete the .blend file soon due to the size (see the page to see exactly how big) and the fact that it can be made in one day if I should ever need it.

Um…Rivenwanderer? That is a very cool object, don’t get me wrong, but that isn’t a Menger’s Sponge. VERY cool pic though! Name it somehting. Name it the Rivenwanderer Sponge!

Hmmm… you’re right. Must have mis-duplicated or something. I’ll rename it soon.
PS- it is true, though, that the pictures make some faces look like they’re on the same plane as some other faces when they really aren’t.

here’s that level 3 sponge http://www.best.com/~calyxa/pearl/1images/menger.jpg I made in Bryce. the scene file is only 19MB - I’ve had larger files… but it did run but of memory once when 1000 I tried to change the material on all the cubes a second time. I’d managed to change them from a metal texture to glass… but then when I tried to change’em back to another material, that’s when it died on me… don’t know if I’ll mess with this again or not, though I may have to check out this notecard thing more thoroughly.

I made one in bryce, but I coudln’t get past level 3. It would crash. Man I wish I could.
That is awesome.
Gandalf82 Guildsman posted 11-21-2000 06:59 PM
Using another method other than duplicating many, many cubes, I DID get very close to a Level 4, but after I made things negative and positive, it died, but I got close!
That was the edited highlights, btw, not the whole thread.
