What it does: for the selected Frame range, have the camera 'look' from the POV of the Layer.
Another way of thinking of this is that the camera is attached to the Layer, and whatever you do to the Layer in a spacial and rotational way now happens to the camera. It is a virtual 'Camera Layer' of sorts now!
There are parameters besides the frame range.
'Use Origin' uses the origin of the Layer instead of its drawn/created location (this establishes the 'virtual origin').
The 'POV Delta' allows moving the camera an (delta_x, delta_y, delta_z) vector away from the virtual origin... for example to get a more realistic 'eye' position.
'Reverse' changes the direction the camera is facing (i.e., if looking out face, now is looking through back of head).
**WARNING**: This also applies to all my other camera tools. All of these work off of transformations performed DIRECTLY to the Layer. Thus, if a Layer is in a PARENT Layer and you move the Parent Layer, this will move the Layer but leave the Camera behind (since the transform was performed on the Parent and not DIRECTLY on the Layer itself).
This can be the source of confusion, or the source of some interesting and powerful tricks!
HOW TO OVERCOME:
- only target layers at the top level (not the child of anything)
- target the parent of the Layer and only move the Layer by moving the Parent
- create an invisible 'focus point' Layer that IS a top level layer, and have it attached to a bone in the layer to be used, and then applying the camera tools to this 'focus point' layer instead of the layer directly will accomplish the desired affect.
