> How do I suppose to define the following items in POVRAY:
> 
> 1-Radiosity parameters
With a radiosity block in the global_settings block. 3.3.4
The simplest:global_settings{radiosity{}}
> 2-Daytime or night time.
Adjust the position and intencity of your light(s). Take a look at lightsys.inc
> 3-Using the soft shadows.
area_light 3.4.7.5
in the light_source deffinition, add
area_light x*VAL, z*VAL, XSamples, ZSamples adaptive 0 circular orient
VAL define the extent of the light
Samples define how many subelements along each axix
adaptive prevent the use of all samples when not needed, gaining speed. change if you
get artefacts.
circular make the light a circle (otherwize, it's square)
orient ensure that it's always properly oriented
> 4-Anti-Aliasing parameters.
quick starting point: +a0.3	3.1.2.8.4
> 5-Diffuse sunlight.
use radiosity and maybe some scathering media	3.6.2
> 6- Direct sunlight.
anything directly lighted by the light acting as the sun
