implemented in audio and video sequencing software, where visualisation of cues in
relation to time is a standard problem; however, it cannot be expected that pupils of
the target group age would, on a general basis, have experience with sequencing
software, whether audio or video (although some of them might). Eventually, one
must remember that, the data which is rendered as cue information must be storable
and retrievable in the database located at a remote server – and technically
implementing a connection between the cue, visually rendered as time related
information in 2D, and effectuation of its content in the 3D world in realtime is yet
another problem, which may (and indeed, does) put additional demands on the
rendering engine.
Finally, it must be stressed the light program that ends up being stored should
be also used as master source for the actual event and the real light show – that means
it has to interface in the world of light consoles, projectors and DMX; and eventually
one mustn’t forget that the entire web project must be eventually be integrated with
the rest of the web content related to the centennial event, possibly meaning transport
of the system to the web server hosting the event related web site. Here it can be
added that the event related web site, will also host the web pages carrying the
webcam streams, as well as general information about the event, however that is out of
the problem scope of this project.
Although it may be difficult to summarise the results of the initial analysis in brief
statements, several classes of problems naturally emerge:
1. Database design, allowance for user distinction and storage of individual
programs, and a corresponding administration interface
2. User authorisation, administration, and data security and integrity
3. Targeting a wide variety of users, and thus wide possible spectrum of
hardware and viewing platforms (both in the sense of monitor displays and
of web browser software), as well as a variety of available bandwidth via
internet connections
4. Delivery of interactive, 3D content through the web – hardware and
software compatibility issues
5. Design of realistic 3D models of the environment for the web interface
6. Design of a realistic preview of the light show within this environment,
dictated by a light program
