I wish to develop an application in which a log can be realistically visualized in 3-D and
then sawn (sectioned) along some arbitrary plane (typically along the length). We have developed
a data base which defines the periphery of the log exterior, the pith of the log (approximately
the center at any x-section), knots within the log, and other assorted significant characteristics
such as mineral stain. There are approximately 800,000 vertices which in a typical log. In order
to have a realistic visualization, I would plan on being able to apply textures which correspond
to sound wood, knots, stain, etc.

My questions then are [1] can this be done (I assume so), [2] is Performer the best software
approach to do this or would some commercial solid modeler work better. I assume Performer would
be cheaper and it seems to me that in most cases an application package just never seems to be
able to quite do what you want. Also, is this a doable project for a reasonably proficient
programmer (say a 2 yr. MS student) or would I be better off hiring a full-time programmer to get
it done in half the time.

I would appreciate any feedback or perspective on these general questions. I will be writing a
proposal shortly (due in 2 weeks) and want to be realistic in what can be done.

Thanks for your time.
