3D model file format with collision?

[jeffmorris]

Which 3D model file format support collision without having to create other files? One of the tutorials on Irrlicht's web site showed me how to load a 3D model and have collision checking. I would like to create a virtual city.

Depends on what you mean by 'support collision'. No model contains a physics engine of any sort, but if you mean collision support as in model 'weight', 'size', 'velocity', etc., I would check out COLLADA.

You can create a basic triangle selector from any model; the source format doesn't matter.

Exception: except it does, because getMesh(s32 frame); is currently borked for skinned animated meshes.

How do I modify the source code for the collision example to load a different 3D mesh file that's not in a compressed file? The collision example loads "map-20kdm2.pk3" compressed file and loads "20kdm2.bsp" 3D mesh from the compressed file. For example, I wish to load "city.3ds" 3D mesh file.

Don't add the pk3 archive and replace the load mesh function's parameter with city.3ds, simple as that!

I can load the city model in meshviewer example but I can't load the city model in collision example or I can't see the city model in collision example. I saw the faerie.md2 model appear for a second before moving off the screen in collision example. How do I slow down the first person camera in meshviewer example?

[JP]

you can slow it down by changing the parameters in smgr->addCameraSceneNodeXXX()

You are free falling, that's why... Look at your gravity and your collision.
