Well, it *is* possible, in a way, to write directly for Macromedia Three-D…take a gander at any 3D Works file. It's in text format. The first section describes the default attributes of various objects. The latter section describes how they act over time. The action is in the lines that begin with a "k", for keyframe. This is where positional data (as well as all other types of data) are stored for each frame. There are also a few other parameters that store type of tweening (linear, spline, etc), ease-ins, etc for each keyframe. I've only done a little bit of work with this stuff, but it's the same approach that the Knowledge Revolution folks take. The formatting is the tough part, although this would just take patience to implement. Unfortunately, I don't know of a full documentation of the file format…I've just doped parts of it out, by twiddling the 3D Works interface, saving, and seeing what the text file says. As far as MacWorld/Boston, the only booth I remember is the NEC area…I think there were three or four others, too. Have you considered contacting Knowledge Revolution directly? They might have a lead on the absorbed power problem…may save a bit of effort, and I'm sure they'd also be interested in the work you're doing.
