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. -kjd ----- Original Message ----- From: "David Yazel" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, February 05, 2002 6:57 PM Subject: Re: [JAVA3D] ROAM and GPU Usage (off-topic) > I just want to weigh in here with an alternate technique.
