This is a question for Jaime! But anyone who has a smart answer.... :-)
I am using Lightsys IV in one of my scenes to simulate outdoors sunlight. I
remark that the shadows are cast by a point light sun. Is it possible to
change that to an area light within Lightsys? I tried by adding the area
light code and scaling that up, but I see no change.
Thanks a lot!!

In my town street scene, I used an area light for the sun, and also
had trouble with it showing the effect... Finally I found that the area
size has to be *really* big for the default DomeSize of skylight.inc
I just did a quick test, adding this area light statement to the sun
light on "demo_outdoor.pov":
area_light 10000*x,10000*y,10,10 jitter adaptive 1 orient circular
and it worked nicely (I tried first with 1000 units, but the area
didn't show).
Hope this helps...

Thank you Jaime!!
I had only tried with a scale of 100... so no surprise I didn't see anything
:-)

Indeed. However, with Lightsys I have no idea what the distance to the "sun"
is. It probably is hidden somewhere but I have not succeded in finding it.

It is on CIE_Skylight.inc (the CIE version of skylight.inc by
Philippe Debar): SolarPosition is based on DomeSize, which is 100000 by
default (you can override it by setting DomeSize before calling the
include).

I overlooked that! Thought I had browsed carefully through everything!
