Effects of hidden geometry?
-
I was pondering this last night and wanted to see what thoughts people have...
if you have a model that has been constructed to show different aspects of the product in different shots, would it render faster if when a shot does not show certain aspects of the build, they were deleted for that shot?
I am thinking that if i model up an electronic toy, and animate the batteries being fitted and the cover plate moving into place in one shot, but then never see the batteries or cover again, and they are not anywhere that would affect lights/reflections etc, would the subsequent shots render faster if i deleted them first?
I don't know if software is intelligent enough to ignore geometry that is not affecting the visible light rays in a scene?
I guess i will be removing these things as its my feeling that the geometyr will still need calculating whether its seen or not.

Hi lightningad,
What influences a scene or not needs to be evaluated. If a geometry is not "water-tight", but contains for the camera invisible objects, doesn't mean that Global Illumination rays might not enter the Item anyway. Just to provide a hint aht it is not always a simple not seen by camera case.
Yes, if it has no influece to the scenetake it out. But if that becomes a lot of managment on the artist side, it needs to be evaluated.
My firm believe is, based on nearly two decades mentoring artists, that not optimized models or textures and rendering parameter are more the problem than a few objects left in the scene. All in all this is a longer them, and to be honest, I have currently time off, so I would love to push this into a Maxon Show as a longer discussion.
All the best
