I've read the description of how povray processes images, and I think I 
know the answer for this, but I want to make sure before I embark on a 
large project.

I am in the process of generating a room (actually a captains quarters 
on a old sailing boat).  The plan is to generate a series of animations 
using this room, although right now I'm just working on making the room. 
  As you may imagine the room is somewhat complex (table, sextant, 
couple of oil lamps, bulkheads, etc).

My question is, when I render does povray ignore the features out of the 
view of the camera?  I've set up most of the objects as macro's, so it's 
easy enough to remove what I don't need for each scene, but I'm 
wondering if that's a waste of my time.

Thanx

Bryan

Out of view objects will take some parsing time. They won't take any notable render
time unless ther 
bounding boxes enter the viewed area. This won't hold if your scene is very complex
and requires the 
use of the swap file.

That depends.  POV-Ray deals well with shapes not affecting the render 
results at all but something being out of direct view does not 
automatically make it not having an effect on the results.  It can for 
example

- be visible in reflections/refractions
- cast shadows
- affect diffuse lighting (radiosity).

Testing for all these is also done in areas not in direct view of the 
camera.
