Hey All,
The subject sez it all. I've been working on this scene and somebody here
suggested it could be a good candidate for radiosity. I've tweaked and
tweaked, trying settings using both common sense and just randomly changing
them (I even read the manual!!!), and can't get good results. Most images
just look brighter than it would be without radiosity. A few times I have
gotten patches of blue all over the brick wall, but what I want is just a
blue tint along the bottom of the brick wall. Following are a couple of
pics and what I hope will be enough info for someone who knows radiosity to
help me.
THE GLOBAL SETTINGS
#if (RadiosityOn = 1)
global_settings {
ambient_light 1.3
radiosity {
brightness 3.3
count 200
nearest_count 8
gray_threshold 0
low_error_factor 0.8
recursion_limit 2
minimum_reuse .02
error_bound .28
distance_maximum 100
}
}
#end
THE FLOOR FINISH
#declare FloorFinish = finish {
ambient 0.30 (when I increase this the floor gets brighter, but I still
don't get a good blue tint on the wall.)
brilliance 3
diffuse 0.4
specular 0.70
roughness 1/60
reflection 0.14
}
THE LIGHT SETTINGS
#declare SqY = 16;
#declare TablHite = SqY*2;
#declare LiteTrans = 100;
#declare LiteX = 42;
#declare LiteY = 30;
#declare LiteBrite = White*1.0;
light_source {
< 0, 0, 0>
color LiteBrite
#if (ImageQ = 1)
area_light <5,0,0>, <5,0,0>, 5, 5
adaptive 1
jitter
fade_distance LiteTrans+71
fade_power 3
#end
translate <0,0,-LiteTrans>
rotate x*LiteX
rotate y*LiteY
translate <0,TablHite,0>
}
The brick wall is on the x-y plane where z = 70.
The bookcase is on the y-z plane where x = 160.
I hope this is enough info.
Thanks,
Eric
