Now you can take any object that has a discreet inside and outside and make
a blob out of it.
This simple death-star, for an easy example, just a sphere with a smaller
sphere CSG'd out of it, and next to it, the blobified version.
This example took 94 seconds to parse, 12 seconds to render
640x480 AA 0.3
Blob resolution = 40
(200 million tokens parsed)
Check in the scenes group for the code.
Note: I'm using the web interface to post this. If that causes headache for
anyone, I'm sorry. I use the web interface to post and read, and I have no
problems at all.

Note: I'm not bothering to manually decipher images that do not show up by
themselves. If that causes ignoring anyone's hard work, I'm sorry.

Maybe this will help...

that does help, thanks.
not having time to read through the include file, is this just a "blobby"
looking object or will it interact with other blob { ... } objects? say, if
you put two of those "Death Star" objects next to each other how would they
interact?

I'm not exactly sure what you're asking. The blobified object is a true
blob.
Speaking of interactions, this bit of code is actually the first part of a
grand scheme where animated objects can interact with each other accurately
wihtout explicitly coding in the movements and interactions...example:
you've got a cube hurtling trough space at another cube, we'll just call
them Borg cubes for now...so imagine your two Borg cubes, both of them
rotated randomly, so they won't just bump into each other face-on. When
they collide, one corner of a cube is going to impact before anything else
(most likely), and at that impact some momentum goes into changing
directions of the cubes, some goes into rotating the cubes...those changes
in momentum can be calculated, depending on masses, normals, centers of
mass, velocities, etc..
And the FIRST step in calculating all those things is to map out the outside
surface of the object/s. So basically, this blobify function does that and
outputs the surface data into a blob.
