Good morning to all,
I'm focusing on a quite strange issue.
I have simply defined this light source:
light_source {
<0,500,-1000>
color rgb <255, 255, 255>
fade_distance 1
fade_power 0
media_interaction off
media_attenuation off
}
and this object:
cylinder {
<0, 0, 1000>,
<0, 1000, 1000>,
(100)
pigment {rgb <0, 0, 0>}
finish {
ambient 0
diffuse 1
specular 1
emission 0
roughness 0.005
reflection {
0.5
metallic
}
then, gradually I'm moving the light source until z=-100000, leaving the camera
fixed:
camera {
perspective
location <0,500,0>
look_at <0,500,1000>
rotate <0, 0, 0>
up <0,2,0>
right <2,0,0>
}
The strange issue is relative to the behaviour of the light reflected by the
cylinder. It seems to increase when I increase the distance between object and
light source. Why? There is any light attenuation defined.
Anyone have an idea about that?
Thank you
Best regards
