Domes, Planetariums, Fisheye, Spherical mirror
The following are documents related to dome projection, including but not limited to, fisheye theory and conversions, the iDome, camera capture and fulldome productions. Included is an image gallery on installations the author has contributed to including both spherical mirror, fisheye lenses and multiple projector systems. Some of the material here relates to the projection into a hemispherical dome using a spherical mirror, a projection technique developed by the author in 2003 and variously referred to as "sphemir" or "mirrordome". In particular, a FAQ, Frequently Asked Questions primarily targeted at those contemplating creating their own dome projection system based upon the spherical mirror.iDome

Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind.
