Hi Umit,
Yes, I am employed on the VENUS project, how on earth do you know that?
I, personally haven't worked with any flocking algorithms, it's a feature I
haven't got round to adding yet. However, I did supervise an MSc student
project on flocking using OSG. In order to simulate fish body motion he used an
animated vertex shader to distort the model with a dampened sine wave (as you
mentioned). With a bit of tinkering this should provide nice results with
minimal effort. However, if you want more accurate movement I think it would
have to be modelled, but then of course you have the problem of loading the
animation into the OSG..
Hope that's of use.
Kim.

Subject: Re: [osg-users] MAX to COLLADA or which format ?
Hi Kim,
Thanks so much for reply. I remember, you have worked on VENUS project. In this
project how can you achieve fish motion modeling? Do you use only shaders to
give special motion mathematics on each skeletal model or do you use
sophisticated tools?
I mean, I want to model school of fish by using Reynold's Flocking Algorithms
and fish motions. At this point Do I have to model each fish motion by using
shaders (for example sinusoaidal travelling wave to modeling fish waving) ? Or
there is another way to to it except osganimation toolkit?
Thanks for advices.
Best Regards.

In my experience the feelingsoftware collada exporter gives the most reliable
results when exporting models from Max. However, as far as I know there is no
way of getting any animation information out of max and into the OSG.
I've noticed that the animation toolkit (osgATK/osgAnimation I forget the
name), mentioned recently in the forum had a Blender importer/exporter that
does support animation. Perhaps that is worth taking a look at.
Hope that is of help.
Kim.

Subject: [osg-users] MAX to COLLADA or which format ?
Hi Folks,
I follows mail list and I know there was a discussion about converting animated
MAX format to any format which osg can understand. I searched the all archive
and want to ask same question again around the different content.
As I said, I have animated MAX format models and want to export another format
in animation too. But after searching, I understand that I only can do this
conversion in COLLADA format. Is it right ? And if right how should I achive? I
found colladamax exporter
http://www.feelingsoftware.com/content/view/65/79/lang,en/ There is anyone who
used this exporter? I am asking because of leading me to right way.
And Does using COLLADA formatted animated model useful or not on simulation
project? I have never use collada format before, so I don't know anything about
the efficiency.
Any advices would be appreciated with glad.
Best Regards.
Umit Uzun
