First post – Creating a hemisphere
I haven’t bought AE yet – I’m looking to fill a specific need and I’m wondering if it can be achieved with AE.
I need to project a video from the “camera” onto the inside of a hemisphere (or it can be a sphere – the nodal point of the camera will be at the centre). The reason it needs to be a sphere is so that it can be merged with other tripod footage that has the same nodal point.
I think I can work out how to do camera projection, it’s the hemisphere I’m struggling with. I do have a backup plan if AE can’t do it, or can’t do it without an additional investment in an expensive plugin.

I’d give CC Sphere a try. Just put you footage in the top half of a comp, with nothing in the bottom. Apply CC Sphere to that precomp layer and you have a hemisphere. Or just mask off the top or bottom half of the layer, and apply CC Sphere. To look right, the footage for a sphere needs to be twice as wide as tall, 2:1 ratio.
Andrew has a setup for making CC Sphere respond to AE’s 3D Camera, done with Dan Ebbert’s lookAt expressions methinks, here:

I’m not sure about adding the other stuff, but you can add many layers with CC Sphere on top of each other. Andrew does that to build an atmosphere (clouds) around Earth in the previous tut:
