How to make a collision detection?

Hello,
I am new to OgreNewt and need to know how to detect a collision of two objects, if you can help me, thank you.

PS. I've seen several tutorials on how to do it but can not follow the reasoning.

PSII. Sorry for my English.

Hello ownh.

Collision Detection, will be made automatically by add newton bodies to your project. you will read OgreNewton tutorials for know how to do that.

additionally you can use ogre raycast for made collisión detection manually.

You need to create material interactions between the bodies. When you pass a shapeID your defining which material it gets. Then you can set how each material interacts with one another OR let newton use it's defaults.
