[Radiance-general] ambient setting for very large scenes

[Jelle Feringa / EZCT Architecture & Design Research]

Hi,

 

I'm struggling a little with setting my ambient parameters.

Thing is that my scene is far larger (~10000m) than my area of interest
(~90m), which is an interior scene.

If I follow the logic of 'setting radiance ambient parameters' part of Lash'
thesis, setting -ar should follow this formula:

 

minimum_distance_between_samples = (aa/max_scene_dimension) / ar

 

Which in my scene would lead to a -ar setting of ~5000. Which seems absurd
to me.

So what would be the appropriate thing to do here?

 

Many thanks,

 

-jelle
