Re: [Algorithms] FW: [CsMain] Scene Graphs

[Scott L. <va...@be...>]

In my experience, flight sims, space shooters, and just about
any other external environment can benefit greatly from either
a plain old scene graph or some sort of minor extension to the
approach since there's relatively little occlusion and lots and
lots of offscreen and out of range culling.  I spent some time
last year considering how to write a portal engine within the
formalism and it seemed like they were apples and oranges
approaches to the same thing in that one is great with external
environments and the other is fantastic when there's lots of
occlusion.

There are some hybrid approaches for situations like dense
urban scenes involving lots of precalculation and bitmasks,
but those would waste a ton of memory if used in a situation
more appropriate for portals.

And that's my two cents and worth every penny!
