In July we will be launching a new site for helloluxx and throughout June we are offering various goodies for you to download. This Orbit Camera Rig is something I use regularly when a specific shot calls for this type of motion.
The camera rig is a really handy little setup with which you can quickly and easily create some nice orbiting moves around your objects using very few animation tracks. The hierarchy of nulls allows you to control the heading, pitch and bank around the pivot point and also from the camera axis, independent of each other. There is also control for the z-depth position of the camera so you can easily push in and pull out as you rotate around.
It is a really simple Xpresso setup as you can see, basically linking the user data to the appropriate object and parameter. There are limits set on the sliders, but you can input higher values manually and if you need to rotate more than this, you can open the User Data Manager and adjust the limits to the sliders in there.
I created a short movie which demonstrates a couple of quick camera moves you can do with this rig, but of course it’s up to you how you abuse the setup.
