SketchUp by automating the export to COLLADA and conversion to OSG.
wow, first time I've heard of this. Nice work.

Hello,
Thank you so much for all these helpful advices. I really appreciate
that.
I already bought the e-book of Rui and started to look into it. I
read also the book of Paul Martz. Great books.
My concern is about the time required for the development of a VR
application with OSG +VR Juggler (we are going to have a CAVE for
neuroscience research) compared to high-level-based engines like
Virtools or Vizard of WorldViz. I dont' know if you know both of them ?
I am evaluating these software in order to decide which one(s) could
fit for our needs.
Thanks again,
Maia

animation systems take their various and sundry examples and export
to VRML or COLLADA. Then examine their other export formats [File
--> Export or whatever menu item does the trick]. The best of the
proprietary formats are 3DS, LWO, OBJ. Now, when I say best or talk
about VRML / X3D / COLLADA, I am talking about the file
interoperability problem. These comments are just my philosophical
workaround.

or import the exported examples and arrange them [you don't need an
artist since I can do this]. I suggest that you give them useful
names and if possible, give them useful names at the nodes that you
may be interested in accessing via OSG for your simulations. There
is no more advice I can give at this point on naming. The Web3D
people tried with the H-Anim standard and other profiles to X3D [See
the Poser character animation system if the university has one]. The
problem domain is huge and nobody seem to be able to make train
loads of money on the solution so there is no satisfactory solution.

know the process for compiling/downloading. You already know how to
access this list for advice.

the issue from a architectural perspective. There are a lot of
architectural programs in the USD 50-150 range that export to VRML
and probably 3DS and OBJ/LWO/DXF. These can be acquired at almost
every Apple Store for the Mac and every Best Buy or Fry's or
whatever giant Canadian electronics superstore is in your area for
the PC [and possibly for the Mac] [Punch!;TurboCAD;...]. A nice city
block or representation of Université Laval would be a starting
point. Then just see if you can get a traffic or pedestrian
simulation completed. This strategy is like using the iPhone's Siri
[or Google Voice] as opposed to Dragon Naturally Speaking. The
learning curve is a little bit easier. But DO NOT FORGET BLENDER
[relatively steep learning curve]. The students need a portfolio.
