I am fairly new to the mailing list so please forgive me if I ask a common question but I have searched the archives and have not found any related to my problem.
My basic problem is that I need to load databases that are in the >1GB range (without textures!!!). Given that I'm not too interested in visualising the whole database at once this is a valid need. The format is undefined but most likely to be openflight or a proprietary derivative. In the past I have used proprietary tools which allowed the database to be loaded in sections (tiles) as requested but if possible would like to use java only code. I can't find an example anywhere where someone has attempted to handle this kind of thing with Java 3D. However, I don't see any reason why such a capability cannot be added to the Java 3D. I have toyed with the idea of implementing an on demand loader but thought I would get some suggestions from the list as to the best architecture and methods for doing this. >From a visualisation point of view it would be nice to load tiles, on a background >thread, based on the current viewing position. However when querying terrain >elevations I need to randomly access any part of the database so perhaps loading a >tile, on the current thread, based on a query to a Group node would be better suited. >Obviously there are time penalties and tradeoffs for such a mechanism but proprietary >tools seem to do the job fairly well. Another slightly different problem I have is that I would like to load SEDRIS format databases if possible. Again it seems like no-one out there has done too much other than a brief query in 1999. Perhaps anyone could offer some suggestions perhaps using geovrml as an interface. regards, Matt =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
