  McIntosh in the Kitchen new version (Message 1 to 10 of 10)

Hi folks,
I wanted to improve my McIntosh image, mostly the table material and the
tubes filaments light emission.
I had to fiddle with radiosity settings. filaments are just high ambient
textured stacked tori, (20  ,2 per valve, arealights should take forever to
trace and point lights should be unrealistic)
I used save & load radiosity data (as found on Jaime's page
http://www.ignorancia.org/t_tips.php ) with higher ambient for the filaments
during the pretrace
I am still not quite satisfied: lighting by filaments is uneven.

Modeled with Moray with some  Luis' DirectCode plugin additions and directly
exported and rendered in Megapov 1.1

A larger version can be found here:

Comments & advices are welcome as usual :-)

here are my radiosity settings

    count           1300
    error_bound    1

    low_error_factor 0.6
    minimum_reuse    .015
    nearest_count  5
    recursion_limit  1

      adc_bailout      0.05
      max_sample       -1.0
      media            off
      normal           on
      always_sample    1

      pretrace_start   0.08
      pretrace_end     0.02


    save_file "rad-save-load.rad"
  #else
    // load settings

    load_file "rad-save-load.rad"
    error_bound 1  // it's important to specify the same value used to save
data
    recursion_limit 1  // also the same if specified
    always_sample off  // no more samples: specially useful with focal blur

Nice version too. It seem that you remove the bump and changed the 
texture of the table...

I must say i like the old version better.  The wood pattern looks 
somewhat strange in this one.

Your comment says it is important to use the same error_bound when 
taking and reusing radiosity data - this is not necessarily the case 
(and to avoid taking too many additional samples in the final trace it 
makes sense to use a higher value there.

I think the same about the wooden tecxture. It will be better to say
"mackintosh in the barn"
The rest is very great as usually with your posts Marc.

Thanks, I still feel dumb in front of radiosity parameters, btw it is not my
comment but Jaime's comment, as I copy/pasted his code and fiddled with
values.
