Domes, Planetariums, Fisheye, Spherical mirror

Some of 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".

Please note that I am available to assist you with your fulldome projection projects. This can be on an informal basis (just email me your questions) all the way to formally quoting, personally doing onsite installations, providing training and ongoing support. I provide the FAQ below which aims at covering common questions, I am available for further consulting at a charge, please email for details.

FAQ: Frequently Asked Questions
Primarily targeted at those contemplating creating their own dome projection system based upon the spherical mirror.
