set mesh as target for Camera?

Can you set a mesh as target for (Maya) camera instead of a 3d point?

Witch point of mesh??
The mesh could be just about anything

I mean make the maya camera's target the center of a 3d object instead of a point in 3d space (vector3df)
PS. Sorry for the confusion (and noobyness)

If you mean an ISceneNode by Mesh, you could use

Code: Select all

camera->setTarget(node->getAbsolutePosition());

Or if you just want the Maya camera to follow the mesh around, you can probably parent the camera to the node.

If i do that wont the camera's rotation get locked?
And thanks RandomMesh, but yeah if i move the mesh the camera doesnt move with it.

You need to call that function each loop. A better option would be to make an animator which causes the camera to track an object

Where is that?

It's between 'while (device->run())' and 'videodr->beginScene();'.

You mean put Camera->setTarget(node->getAbsolutePosition(); between
while(device->run()) and driver->beginScene?
Ive tried that. When i move the object, camera stays (im using movement code from Example 4 like i said)

Hm, not sure if that works for maya camera. The point of the maya-cam is that it is user-controlled, so it will probably override any targets you set. Maybe doing an updateAbsolutePosition() after setting it would help, but I haven't tried.

It didnt work, too bad. Cause than i would have a 3rd person camera the style i want (rotate it along your character manually).
Edit. Okay ill make a custom one.
