The following provides specifications, example applications, and general photographs and informationrelated to the iDome .... a personal hemispherical dome environment.While the iDome can use a fisheye lens on a data projector, the projection systemused below is based upon the spherical mirror, an innovation by the author.

The following illustrates a modified version of my spherical projection for planetarium domesfor an upright dome. In this case a truncated dome, a common arrangementwhen using a fisheye lens and a standard data projector. The projectorhere points towards the floor where the spherical mirror is positioned. Partial or almost complete dome projection can be achieved.
The images to be projected are fisheye and are warped (using texturesapplied to a mesh in OpenGL). The only trick then is to derive thetexture coordinates, this is achieved by writing a simulator that replicatesthe optical geometry of the physical system. Rays are traced throughpoints on the image plane, they are reflected by the mirror and the intersectionon the dome determined. Using this information the (u,v) texture coordinatesfor the point on the image plane can be calculated.

The following show the system in operation on a 3m diameter fibreglassdome. The application is called 'panodome' and allows apanoramic, cubic, or spherical map to be interactively navigated, thefisheye and warping is computed in real time on the laptop shown (Mac OS-X).
As can be seen by the simulations and photos above, the mirror doesn't reflectlight onto the whole dome surface and only a limited area of the projected imageis used. One might ask whether there is an optimal mirror shape that both fillsthe dome and uses as many pixels as possible. As a simpler problem (consideredbecause of the simpler fabrication) is to consider an oblate spherical surface.In the following a raytracing program is used to capture the image on theoblate mirror, the dome is created as a longitude/latitude frame, the camera (red cone) islocated where the projector would normally be mounted and camera frustum isarranged to match the projector frustum.
The parameters are carefully chosen to full the dome and maximise the area on themirror. The image as seen with the camera is shown below. From symmetry if the followingimage is projected it will fill the dome as shown above.

The iDomewas initial created using a fisheye lens (iCinema, UNSW) and then mostly used a sphericalmirror projection. The following illustrates how multiple projectors may be used. One constraintwas to limit the number of projectors to 4, this is because 4 projectors can be reasonablydriven from a single computer thus avoiding the complications when one moves to a cluster.In the following two cases a 4x3 aspect projector is imagined (eg: SXGA+ [1400x1050]) and thelens employed is a 1:1 throw (distance to width).
