We use Director (via our DART xtra), and we use Ogre.  We've looked =20
at Irrlicht (not bad, just not as functional as Ogre), and other game =20=

engines.  We've also used OpenSceneGraph, but moved that project to =20
Ogre (for a variety of reasons not wholly based on the functionality =20
of the libraries).

Hello all,

=20

What 3D engines are people using at the moment?  I know there used to be
the ARToolkit-OpenVRML bundle; is that the most common choice?

=20

Using some examples from the web I went through the grief of coding a
3ds loader and renderer that I've used for about 2 years or so, but to
be honest it just doesn't look very good.

=20

Any other experiences?  Maybe OGRE or Irrlicht?

=20

Thanks

=20

Matthew

Dear Matthew,

I have combined in the past a 3ds parser with ARToolkit and it worked 
really well. Although it was a bit slower than OpenVRML, it provided 
much better realism in the augmented scene.

Best regards,
Fotis

Hi Matthew,

we developed a module for OpenSceneGraph called osgART 
(http://www.artoolworks.com/community/osgart/) at the HIT Lab NZ. We 
have other modules for most of the other engines in the cue or ready 
in-house. Bottom line of all of this is that the choice for a 3D engine 
really depends on the problem you want to solve.


Cheers,
Hartmut

Dear Matthew,

for our student projects we use Panda3D with ARToolkit. Both connect via 
VRPN and a module called ARTrack which we developed to connect VRPN and 
ARToolkit.

best wishes,
Steffi

As Hartmut already mentioned, the choice of a 3D engine is highly
problem specific - no engine solves all the problems.
I suggest putting the main focus on the graphical problems you want to
solve.

Basically any good 3D engine will allow you to specify model
transformation and camera specification using matrices so a simple
ARToolKit integration is trivial and should take less than an hour if
you know the 3D engine well.
If you want do a clean design you should consider the many paper that
were published about integrating tracking solutions into 3D engines.

Here are some categories you might want to consider:
- Open source vs. closed source
- Supported platforms
- OpenGL vs. proprietary (DirectX)
- Scripting support
- Shader support
- Active community
- Model loaders/exporters

bye,
Daniel
