Real time 3D that rund on mac and pc

We have worked with both Quest3D and Turntool for quite a while now - also looked at Ogre 3D for a bit, but all of these are buildt around DirectX and currently I have a client that needs to run realtime content from a mac - anyone heard of any cross platform real time engines?

Open GL should be platform independent, so maybe one of the ol’ vrml clients would do - but which one?

I don’t actually own a mac so difficult to test. Tempted to just tell client to get a PC.

It’s a VRML client, which works fine on win and osx. It have many additonal nodes and materialextensions.

Cortona was my choice some years ago, when i needed it for a client who prefer the not so common OS :wink:

If you can, wait for Unity3D. It will be available for Windows soon !!
