I have to read up on this terminology.  Raster vs fractal vs procedural terrains vs functions.  Its all confusing to me.

If I want to bring in a High Resolution Google Earth 4096 x 4096 tiff file into Bryce, vue, Mojoworld or even in Maya I don't know what they would call this?  A Bump map?  It will obviously not display a render of the original Photo in 3D.
