Rigging a walkthrough camera

- [Instructor] An architectural walkthrough is a…standard form of visualization that can be…highly effective in communicating a sense of…space to an audience.…A simple animation rig gives the designer…the ability to direct that animation while…freeing her or him from the task of…micromanaging all the position…rotation values manually.…Setting up a good walkthrough involves…more than just putting the camera on a path.…If the camera is directly constrained to a…motion path or spline curve,…its rotations will either follow the tangent…of the curve or the camera will…not rotate at all.…

If the camera follows the curve…it rotates so that its line of sight…stays tangential to the curve.…The camera always points directly…in the direction of travel.…The camera can't turn side to side or…up and down as it travels.…This is very unnatural and gives the…effect of tunnel vision.…We need to animate the camera,…even just a little bit so that it's not…always looking straight ahead.…If we disable automatic rotations…from the path,…then we need to animate rotations manually.…
