I am not sure what function in ISceneCollisionManager I can use to do picking of objects.

I want to click on mesh nodes or whatever is on screen and get that object which was clicked on by the mouse pointer?

The simplest method is using: ISceneCollisionManager::getSceneNodeFromScreenCoordinatesBB

This method only takes bounding boxes into consideration though, if you need more precision you should probably use

 line3d<f32> ray = colmgr->getRayFromScreenCoordinates(device->getCursorControl()->getPosition(), camera);

This returns a ray which goes though the camera and points to where the cursor is pointing, then use:


to find the first scene node intersecting this ray
