Technical Notes:
I.E.: Generally useless information, provided for the benefit of other
Sculpt-Animate 3D fanatics and for the terminably curious README reader.
This disk contains a ray-traced animation showing three colored balls
flying in circles above a mirrored bowl (hence the name). This is the
second version of this animation, not counting wireframe and paint mode
previews. The first version, Bowl1, took about 8 days to render all 36
frames at about 5 hours per frame. The frames averaged around 40K apeice.
Rendering time doubled for Bowl2, going to about 10 hours per frame and
just over 2 weeks for the whole thing. Image file size went up to about
47K.
Lessons Learned: (for other Sculpt-3D'ers)
1) I couldn't get moving observer and targets to work at all. I
had planned to have the observer orbit a stationary scene and ended
up with each of the balls following a circular path over the bowl.
If anyone has been able to connect the Location or Target to a path,
please please let me know (send mail to Vern Staats on the AFIT board,
or vstaats on BIX).
Oops, cancel that! Someone else on BIX had the same problem, and
Byte-by-Byte cleared it up for us. Here's how: After creating and
naming a path, skip down to Offspring, enter the name "location" or
"target", go back up to the Parent and exit the Name Path gadget. Now
the path is named (say as "locpath") and it has an offspring named
"location", which doesn't really exist as an object. The gadget will
squawk if you OK-Exit while it's pointing at "location" (which must be
a disembodied name) so you have to exit with the gadget pointing at a
legitimate object. A Cancel-Exit might work as well.
2) Don't be afraid to duplicate vertices when necessary. The bowl is
actually three pieces: an outer shell, an edge, and a mirror textured
inner bowl. I had tried to skimp on vertices by selecting the inner
edge vertices to be part of the bowl object and part of the edge object.
Even though it was clear to me which facets should be mirrored, Sculpt
got confused and bled color and texture across objects. Perhaps a
vertex may only belong to one named object.
3) I think it's a good idea to name everything. De/Selecting objects
by name makes the de/selector tools much more useful.
4) Don't set Motion Blur when building a new animation. Motion Blur is
applied during image compression and doesn't affect the still images.
If you set Save Images, you can rebuild the animation later with Motion
Blur turned on. Compression time and anim file size will be increased
dramatically. In my case, the anim file became too large to play back,
and had to be archived just to fit on a disk. I made a shortened version
and found I didn't like the effect anyway.
5) If you reboot or have a power failure while building the animation,
you can restart at the frame that was being built when the system
crashed. When you tell SA3D to go Render All, it looks to see which
files exist and starts rendering at the first one that's missing. It
doesn't care what's in the file or how big it is, just that it exists
and has the right name. You can render images to a floppy, even if it
isn't big enough to hold them all, shuffle files off to another as it
gets full, and then shuffle them back on for compression.
6) Always Always cancel out of the "Edit Erase Named Vertices" gadget.
The gadget will erase the current vertices if you click on either the
"erase vertices" or the "OK" button. It's too easy to do all your
erases with the erase button, think "OK, I'm done", and click/boom
there goes a whole set of good vertices.
