I don't quite know how to word this, how do I set an object so it cannot block
others (and make them invisible) in the dynavis type culling? This is c++
source code I mean not a map file.

Subject: Re: [CsMain] Support for swept sphere collision testing
Well with camera it does point collisions and sometimes if it doesn't collide
with the wall then it can still intersect halfway in. Therefore you do several
raycasts but it still doesn't play nice because it's discrete hit detections
that you interpolate with.
Atm, it has an offset value from wall depending on distance to player but
this is a bit weird since the camera has to protect from flipping along the
trajectory... Lot's of suboptimal solutions to give the camera volume, swept
sphere is most similar shaped/fastest for a camera. And maybe swept sphere can
also be squashed :D

So you want to use something like caped cylinder collider for your camera?
If you don't use physics engine in your app then unfortunately you'll
probably need add yourself some interface in cs physics wrapper to use its
collision queries directly (it was not there when I've last looked on it).
If you use physics engine and then you can use DynamicsSystemCollider
interface for objects that present coliderrs only.
BTW. why do you need that for camera? I thought that typicly you will use
it for character controller.

It is best way to give a camera volume I think because point
representation is just crappy and a box doesn't represent a viewing volume as
good as a half sphere (as wide as view angle) for which a swept sphere is best.

Ok, but I'm not sure how this works to use bullet to do non dynamics
based collision detection.

Just wondering, did you check if Bullet supports that ?
A quick search hints that this notion exists in Bullet...
