Ambient Parameters

Dynamic ambient parameters:

• rain 0..1 rain intensity
• windy 0..1 wind streght (0 m/s ->0, 20 m/s -> 1)
• night 0..1 night "intensity"
• deadBody 0..1 is the place close to a dead body? (0 m ->1, 10 m -> 0)

Static ambient parameters:

• meadow 0..1 how much does the surrounding have a character of a meadow
• trees 0..1 how many tress are growing in the area
• forest 0..1 forest density
• hills 0..1 how much is the place "hilly" (160 ASL -> 0, 400 ASL -> 1)
• houses 0..1 how many houses or other building are around
• sea 0..1 is the place close to a sea? (0 m->1, approx. 100 m->0)
• waterDepth 0..M where M is the actual water depth, and 0 on land.
• camDepth 0..1 ???

Operators:

• mathematical operators
• randomGen N float from 0 to N
• factor [p,q] (V-p/q-p)
• interpolate [p,q,r,s] (V-p/q-p)*(s-r) + r

Parameters can be combined into Simple Expressions, like:

"meadow * (1 - rain) * (1 - night)"
"(10 - (5 * rain)) * (1 - sea) * (windy factor [0.2, 0.5])"
