Lightflow interiors test- long time renders


(Skates) #1

Just a stupid cup with juice or something in it. Supposedly it has a “dust” interior set on it, but I must have done something wrong because it doesn’t look like much, does it? I’m rendering a really really HQ version tonight with blurred refraction, different interior, super high res radiosity, the works…I hope it finishes in the next 12 years. Actually it was taking about 10 minutes for the 5x5 stage…uhhh… well if it ever finishes I’ll update this one.

not bad ,it looks like you need to make the cup thicker to get a
better refraction and glassy look.also the placement of the lights
effects the caustics,dont know why it takes so long to render,
a scene like yours only took less than 5 min for me?

on the other hand the same scene with virtualight at 320 x 256
took 35 min uuugh!

keep pluggin,itll be worth it!

Nice,

rixtr66 is right, it looks like a (transparent) paper cup, not a glass (see http://www.elysiun.com/viewtopic.php?t=1925 for a glass :stuck_out_tongue: )

Would you share your settings for the purple liquid? I filled my glass with a red one but it looks pretty dumb, your’s muche better…

as S68 said, it doesnt look like glass at all :-? . but besides that, it looks pretty cool. but where are the caus… - oh yea, the glass is too thin! make it thicker and kick the lover’s ass.

hey! it is glass, just really thin. Actually I set the IOR lower than glass so…not quite glass, it’s supposed to be one of those really thin plastic cups. No caustics because I didn’t run radiosity and didn’t turn on fake transmission and used shadowmapped lights. Therefore, no caustics. It saves time. As for the purple liquid: it’s green! And, I guess I can post the material for that.

liquid = s.newInterior( “standard”, [ “kaf”, vector3(0.9, 0.88, 0.9) ])

s.interiorBegin(liquid)

LFMAT3 = s.newMaterial( “physical”,
[ “fresnel”, 1,
“IOR”, 1.33,
“kr”, vector3( .37, .66, .34 ),
“kt”, vector3( .37, .66, .34 ),
“kd”, 0.07,
“km”, 0.02,
“shinyness”, 0.9,
“radiosity”, 0,
“caustics”, 4, 4, ] )
s.interiorEnd()

NOTE: haven’t rendered this one out yet, the interior should look much more opaque.

Maybe you’ll find this list usefull :slight_smile:

Yup, mispelled… I saw it was green :stuck_out_tongue:

Thanx a lot for your material setting. My wine is

VINO

Vino = s.newMaterial(“generic”,[
“kdr” , vector3( 0.25000 , 0.05000 , 0.07500) ,
“kdt” , vector3( 0.25000 , 0.05000 , 0.07500) ,
“ksr” , vector3( 0.50000 , 0.10000 , 0.15000) , vector3( 0.50000 , 0.10000 , 0.15000) ,
“kst” , vector3( 1.00000 , 0.20000 , 0.30000) , vector3( 1.00000 , 0.20000 , 0.30000) ,
“kr” , vector3( 1.00000 , 1.00000 , 1.00000) ,
“kt” , Color ,
“km” , 0.01000 ,
“IOR” , 1.33000 ,
“fresnel” , 1 , 0.10000 , 0.10000 ,
“shinyness” , 0.50000 ,
“radiosity” , 0 ,
“transmission” , 0 ,
“caustics” , 2 , 2
])

And is much less nice…

yeah, I find that the physical type is the easiest to use because you only need to set 2 colors, you don’t have to worry about ksr, kst, etc etc. It’s much easier although I don’t know which material is faster.
