Re: [JAVA3D] ROAM and GPU Usage (off-topic)

Can the various techniques for large terrains discussed in this thread all be layered over
Java3D?

David,

It looks like your method of handling terrain is similar to the tile-based
system described in Game Programming Gems 2.  This is the same approach I'm
using.  It may not be as sexy as ROAM or VIPM, but it's reputed to be
faster.  And I believe it's far more scene-graph friendly.  The tricky part
is coming up with a good method for swapping out tiles when you're on the
boarders of tiles.  4-corner areas I expect to be tricky.

Originally my idea was to use 8x8 tiles, but while working out my own
design, GPG2 was published.  It's nice to hear others are using this method
and I'm not completely daft.  At least, not daft about this idea.

I just want to weigh in here with an alternate technique.  This technique

is

optimized for fairly slow movement speeds.  Our current implementation can
handle up to 50 meters a second without a problem, but after that it can't
keep up.  Not a problem for us, but could be for other people.
