i just found this very useful component,
i had a custom-made all this time but this one helps a lot with teaching, just one comment:
The maximum scene size considered by Radiance is calculated as follows:
1.The bounding box is calculated as the minimum axis-aligned parallelopiped that will enclose all objects.
2.The largest dimension of that box (either x or y or z) is considered the “maximum scene size”.
Here is a screenshot of the max scene size calculated in radiance,
a 3x4x3 cube (axis-aligned) and a sky are generated, then they are merged in an octree
and then using the getinfo -d we get max scene size = 4.00002 (e.g. not 5)
I hope this helps
