Why should I consider a good seamless dome surface instead of a dome constructed from planar faces?
As with a lot of things this is often a matter of budget. The bottom line is that something magical happens when one looses sight of the dome (projection) surface. When this happens the human visual system kicks in and creates both an immersive sense and often a sense of 3D depth. This hiding of the projection surface is unlikely to occur with a panel/tiled dome surface.
