Can I use movies from planetarium content providers with the spherical mirror projection?
Definitely! The planetarium industry is used to using movies where each frame is a fisheye projection, typically running at 30fps. This is the natural image formats for projection into a hemispherical display, as such it is also the natural format for projection using a spherical mirror. The only “trick” is getting the content supplier to provide the movies at the appropriate resolution and in the right file format. Some/most suppliers will ship raw frames on request in which case you can create your favourite movie format.
