RTSP Streaming allows a server to only send the movie as needed. It is
not 'downloaded' so there is no concern with having enough free space on
the client. Also, the streaming server allows immediate access to any
section of the animation (with only a small wait for buffering a few
frames). This animation has been compressed and should stream well over a
modem connection. length 10 minutes with 6 fps - size 3.5Mb | |

Http delivery treats the movie as a standard web file. Here the
file must be downloaded to the client. Once it is downloaded it can be
scanned quickly. There are a few tricks to allow movies to begin playing
before they are completely downloaded, but it must be downloaded
incrementally. (no peeking ahead or skipping sections). This movie is the
raw output from the OrcaRecorder, it is about three times larger than the
compressed one used for streaming. length 10 minutes with 6 fps - size 10Mb | |

QuickTime VR provides a way to let the user interact a bit more
with a Movie. Here 'movies' are made out of a two dimension array of
images. To interact with the model, mouse click on the image and drag up
and down or right and left. Most often this is used to 'spin' a three dimensional
object, but there is no reason that it could be used for navigating through
tours somehow. With this model the up and down movement 'jumps' because i
have done a bad job of building it.... and don't yet have the tools to do
a better job. For other examples of this see theshowcase
that apple has put together.
