thinking in "actual" opensim scene implementation, not "ogre meshes", for
example):
- The creation of converters between "primitives" and 3D "usual" graphic
formats (described by 3D points, lights, etc etc).
- The use of Collada extensions for primitives, with the disavantage of not
to be "directly" imported into 3D programs.

Actually we can import from Autocad (Henshin), 3dsmax (Prim composer), Maya
(SLTk), blender, Sketchup... but all of them use a distinct format. We need
an unified format, that is clear, but Collada...

There are plugins for "collading" 3Dsmax designs (some for autocad too, kml
converters and so on) but, by now, I haven't seen anything usable into
Opensim without a great development effort for "reconverting" collada files.

My conclusion (always personal opinions from someone who needs something
"right now"): too much work for poor results.

Greetings.

Hi everybody:<br><br>Months ago I've been evaluating Collada as a format for my Henshin project (autocad to sl and opensim). Though Collada is more "3D vertex" oriented than "primitive oriented" it allows to define something like "extensions".<br>

</div> From the standpoint of yet another user of OpenSim, I echo this desire<br>
to use Blender (which<br>
we use on other projects) for forming and manipulating geometry and then<br>
being able<br>
to import into SL. The actual format (Collada, X3D,...) to us is less<br>
important than the sheer<br>
ability to enrich the variety of geometry types that SL can display<br>
(perhaps through he evolving<br>
Rex viewer). In-world SL-style prim construction is nice, but it just<br>
doesn't cut it for richer<br>
environments. Meshes are a good start. Also, how about the parametric<br>
nature of spline<br>
surfaces (this would be efficient from a communications standpoint since<br>
the client does the<br>
leg-work on rendering the surfaces)?<br>
