7.5.3 Adjusting Radiosity

As described earlier, radiosity is turned on by using the radiosity { } block in global_setting. Radiosity has many parameters that are specified as follows:

  global_settings { radiosity { [RADIOSITY_ITEMS...] } }

RADIOSITY_ITEMS:
  adc_bailout Float | always_sample Bool | brightness Float | 
  count Integer | error_bound Float | gray_threshold Float |
  load_file Filename | low_error_factor Float | 
  max_sample Float |
  media Bool | minimum_reuse Float | nearest_count Integer |
  normal Bool | pretrace_end Float | pretrace_start Float |
  recursion_limit Integer | save_file Filename
