full dome and stereoscopy don’t mix too well. it works ok in imax-style theaters, but if you do not have a controlled focus (for example when people are allowed to walk during the show, or sit in a circle) you will have to compromise massively.
it can be alright if you only do a panorama or rotunda (and some left-right distortion, depending on the depth of objects), but stereoskopy in the apex of the dome is hardly possible (because in most cases you do not know which angle the eyes have and therefore in which direction you should do the left-right-distortion).
i have a new setup for dx11 for fulldome, and i think i’ll release it sometime next month, while i am at the SAT in Montreal. the setup is fully based on cubemaps (awesome work by unc) and allows for moving the sweetspot in the dome in realtime.
