How to make the camera look at point in 3d space?

This is a really stupid question,but how can I do it?
When I write
camera->setTarget(core::vector3d(10,10,10));
or something like that,the effect is not that I had expected!

hi
with this code the camera looks to 0,5,0
smgr->addCameraSceneNode(0, vector3df(0,30,-40), vector3df(0,5,0));
it should works bye bye

No,I need this action to be done in dynamic way!
We got a point in 3d space-we make the camera to face it.
Another point-the same camera-the same action...
How this can be done?
Code please!!!

what is the result you expect and what is the actual result?

camera->setTarget(core::vector3d(10,10,10)) should leave the camera in the same position but suddenly change it's direction so the point (10,10,10) is right in the middle of the camera's view

Have you tested this function?
I expected the same,but in reality it doesn't work so!

I have tested it and it works fine for me with a normal camera scene node (I haven't tried it with an FPS or Maya camera)

are you sure that the point (10,10,10) is the right point? for instance, try adding a test scene node and putting it at that position, then seeing if camera->setTarget points the camera to it or not
