[Bluesphere3d-developers] Design Discussion

[<ars...@bt...>]

Hi,
   Before we do much more with the project, we had better discuss how we aim to have bluepshere store the model data to be worked with in memory.  Personally, I have no clue about things like this, but was thinking from my amateurish perspective that maybe holding things in STL vectors would be handy.  I suppose, however, that it could become very inefficient to have to loop through large numbers of vertices in large models for selections, etc.  I've had an extremely brief glance at the sources of Aztec3D - another OSS 3D app here at sourceforge, and they seem to be using something called a range tree, but I've never really heard of that before - . Have any of you come into contact with that method, and do you think they'd be any help?  Sorry for making such an abstract post, but this is probably something we need to discuss.

John

P.S. Here is some of the RangeTree code for anyone, who, like m
