maya camera zoom and position

[HiGuys]

im trying to use maya camera to display my 3d data.

i want to set the point of rotation to the center of my 3D data.


ICameraSceneNode* camera = smgr->addCameraSceneNodeMaya();
if (camera){
camera->setTarget(core::vector3df(350, 80, 100));
camera->bindTargetAndRotation(1);
camera->setFarValue(200000.0f);
}

this is the code. how i can control the rotate point?

Also i found that i can use zoom by clicking the mouse wheel and drag the mouse to left of right.

But, i want to use zoom by rolling the mouse wheel.
Can i change it like this?

Im superb beginner.

Please help me
Thanks.

The camera-animators are pretty simple and basically for quick prototyping. If you need more than they offer (like you do here) you will have to write your own camera-animator. You can look at the code of the existing ones to get an idea how to do that.
