Hi,
I wonder if I need to change my PC. It is a Pentium II notebook,
with 256MB memory runing NT4 at ??unknown MHz??
It took me about 20 hours to render the following code.
Any one to check with a more recent machine?
#include "colors.inc"
#include "metals.inc"
#include "functions.inc"
light_source
{
<10, 10, 10>
color rgb 1.0
}
light_source
{
<-5, -5, -10>
color rgb 1.0
}
camera
{
location <0.0 , 5.0 ,-7.0>
look_at <0.0 , 0.0 , 0.0>
right x*image_width/image_height
}
// function(x,y,z) { -(sin(5*sqrt(x*x + z*z)+0.00001))/(5*sqrt(x*x +
z*z)+0.00001) + y } // onde
// function {
f_spiral(sin(3*atan2(z,x)),y,-3+sqrt(x^2+z^2),0.3,0.1,3,1,1,1.5) } //
disque avec 6 spirales
isosurface {
function {
f_spiral(sin(3*atan2(z,x)),-3+sqrt(x^2+z^2+y^2),y,0.3,0.1,3,1,1,1.5) }
// alternative declared function
contained_by { sphere { 0, 3.2 } } // container shape
//threshold 0.0 // optional threshold value for
isosurface [0.0]
accuracy 0.001 // accuracy of calculation
[0.001]
max_gradient 11 // maximum gradient the
function can have [1.1]
//evaluate 1, 1.2, 0.99 // evaluate the maximum gradient
//max_trace 1 // maybe increase for use in CSG
[1]
texture {
bozo
texture_map {
[0 T_Gold_3C]
[0.25 T_Gold_3E]
[0.5 T_Chrome_3E]
[0.75 T_Chrome_3E]
[1 T_Gold_3C]
}
}
}
with this ini file:
[1024x768, AA 0.3]
Width=1024
Height=768
Antialias=On
Antialias_Threshold=0.3

I don't think 20 is so bad, taking into account that you used multiple
lights, isosurfaces and reflective textures, and rendered picture with
anti-aliasing and to quite big size. Isosurfaces are not fast.

I rendered it in 53 min at 512x384, AA0.3 on my 1.333MHz Athlon. That
would make it about 3.53 hours at your resolution. My 300MHz PII takes
about 5 times as long, ie 17.65 hours, so if your PII is 266MHz, it is
running as it should.

It took 7h8m27s in the Celeron 600MHz 128MB RAM I use at work, at 1024x768
AA0.3.

5 hours 2 minutes and 10 seconds on a Pentium 4 1.4Ghz, WinME.
My Athlon 1.3 Ghz at home is faster, but I ran this at the office.

All right, I'm going to buy a new one.

We just got a new used computer store in our town, PII 200-400s in the
$20 range. I am thinking about setting up a small network just to send
renders to a spare 400.

Do they ship overseas? If so, how much do they charge?

I doubt it, but I could ask. They buy replaced equipment from
corporations, surely that is happening in other countries, if not now, soon.

Oh it's happening alright, but not anywhere near the $20 range...
Anyway, if it is a local store I also doubt they would be willing to engage
the paperwork hassle that the Brazilian government would unleash at hem like
a pack of rabid dobermanns...
Thanks,
Ruy
