| default finish:
 
 
   default finish| #default{ finish{ ambient 0.1 diffuse 0.9 }}   |  | 
 | In POV-Ray version 3.7 with radiosity ambient is replaces by emission. With radiosity on ambient is 0. For 3.7 scenes that work also in 3.6 use i.e.:
 
 
   ambient <-> emission| #if (version < 3.7) ambient 1 #else emission 1 #end   |  | 
 | default gamma setting: (3.6/3.7) 
 
   default finish and gamma setting versions 3.6.2 / 3.7| global_settings{ assumed_gamma 1.0 }
#default{ finish{ ambient 0.1 diffuse 0.9 }}    |  | 
 | max_trace_level: 
 
   max_trace_level 10| global_settings { max_trace_level 10 }//(1...256) [default = 5]    |  | 
 | charset: 
 
   charset - specifies the assumed character set of all text strings| global_settings{ charset utf8 }  // unicode  
global_settings{ charset ascii } // ascii (only 0 to 127 are valid)
global_settings{ charset sys }   // system specific charset   |  |

 | 
   noise_generator 3| global_settings {  noise_generator 1 }    |  | 
 | adc_bailout 
 
   adc_bailout - sets cutoff point of ray computation (1/255 default)| global_settings{ adc_bailout 0.0039 }     |  | 
 | number_of_waves 
 
   number_of_waves - sets how many instances of waves/ripples to use| global_settings{ number_of_waves 10 }     |  | 
 | irid_wavelength 
 
   irid_wavelength - sets the color shifts for iridescence (irid {})| global_settings{ irid_wavelength <0.25, 0.18, 0.14> }   |  | 
 | hf_gray_16 
 
   hf_gray_16 - sets image output to use grayscale only (TGA, PNG)| global_settings{ hf_gray_16 on } // [on/off]   |  | 
 | max_intersections: // don't use it with POV-Ray version 3.7 !!!! 
 
   max_intersections 200| global_settings { max_intersections 200 } //(1...200) [default = 64]    |  |
