hi
impillo
i found a strange thing about luminaire simulation:
i tried light+brightdata to map on a sphere the luminance desired
(evaluated by ies2rad) , it works, i see the light on the walls and the
light emitting ball...
but the STRANGE thing is that where the luminous flux is expected to be
hi (lower side of the ball),
the luminance is low...
if you look at the scene you see floor and low portion of wall that
receive light BUT the ball is dark (upper luminance >lower luminance)
this is not correct.
i ll appreciate any help to solve this strange problem
to share this with others i m sending all the file involved
so, if you are interested, please copy each of them to a file with same
name you
you find between double line of "########"
and then run.sh
what do you think about?????
look the ball, loot the walls... the ball is upside!!!!
again thanks,

this is not correct.
i ll appreciate any help to solve this strange problem

so, if you are interested, please copy each of them to a file with

you find between double line of "########"
