I'm still trying to find a good CAD program for domes & such.
-I've found Rick Bono's "Dome" program (v. 4.6) to be wonderful for
generating raytraceable files for POVRay. (Although the 'export to *.dwx
format' function gives a less-than-desirable simple-wireframe of a dome. This
is OK for importing into Bryce 3D, but it lacks the mechanical detail that is
possible with POV.)
-and Gerald deJong's "Struck!" to be great for octet-truss designs (although
you have to build the truss by hand, it's not a programattic interface where
you say "make me a truss with these dimensions")
-and Moray 3 to be a FANTASTIC 3D modeller/interface to POVRay (I'll be
posting some new pictures on the website soon, although I haven't figured out
how to import POV scenes from Dome into the modeller, you can import other
items from Moray directly into POV. Moray lets you get *extremely* precise in
dealing with your designs. Down to units of measurement that go to 5 decimal
places. (0.00001 units, which, if 1=1 meter, then 0.00001 is 1/100th of a
millimeter.) This is just fine, but I don't know if it's compatible with other
CAD programs or how to interchangeable with them, yet...
-There's another POV-compatible freeware modeller, called POVLab. I haven't
played with that one, but I've seen examples of what it can do. VERY nice.
Here are some relevant links:
Dome 4.6: http://www.cris.com/~Rjbono/html/domes.html (Freeware)
Bryce: http://www.metacreations.com/products/bryce4 (Commercial)
Struck!: http://www.beautifulcode.nl/ (Freeware)
POVRay3: http://www.povray.org/ (Freeware)
Moray3: http://www.stmuc.com/ (Shareware)
POVLab: http://www.povlab.org/povlab.asp (Freeware)
Code notes: I think that Dome, POVRay, and definitely POVLab are open-source.
Bryce is not. Struck might be. There's a community mailing list devoted to it,
but I'm not sure if they all write code, or just Gerald. It's done in Java,
and is used to visualize tensegrities & synergetic geometry in 3D/VRML. The
mailing list is at http://www.fluidiom.com/
Hope this helps. It's enough to get you started, in any event. (It's kept me
busy for the better part of the last year (And probably the next several! :-)
I'll put together some pictures of things I've done with these tools, so you
can see some examples of what's possible. I'm planning on using a combination
of these to render pictures of the autonomous house. Obviously, I'll be
posting pictures of that here when I've got something worth showing.
