I just found out that it is possible to view Google Street View in
Google Earth. The full version not the plugin.
They have improved the transitions from point to point. Before it
was a global slide or zoom, now there is an
interpolation of the imagery data allowing a more
fluid transition between nodes.
The mouse wheel no longer
is used to zoom but to move forward or backwards on the road. So it is possible to basically run
street displaying only the low resolution images until you pause
then the higher resolution images are displayed. Moving slower a
step at a time the high resolution images are used.
There is still lots of room for improvement for the transitions, but
I find it is much easier to stay oriented moving down the street.
