Rainbows

Rainbows are automatically generated by trueSKY providing that a number of conditions are met.

Rainbows can be fully customised, from position to strength and colour of the rainbow.

Variable Definition Value
Automatic Rainbow Position Whether the rainbow follows the antisolar/antilunar point, or is manually set. Bool
Elevation If the automatic positioning is disabled, this sets the elevation of the rainbow. 0.0 to -90.0
Azimuth If the automatic positioning is disabled, this sets the azimuth of the rainbow. 0.0 to 360.0
Intensity Controls the overall brightness of the rainbow. 0.0 to 10.0
Depth Position The point at which the rainbow intersects the terrain. (Dependent a forward/reverse depth) 0.0 to 1.0
Allow Occluded Rainbows Whether trueSKY should generate rainbows regardless of light occlusion. Bool
Allow Lunar Rainbows Whether trueSKY should generate rainbows using the moon’s light. Bool
Variable Definition Value
Rain Speed (m/s) Speed at which raindrops will fall, which adjusts any ‘flutter’ seen in the Rain Streaks, which are used for the rainbow. 0.0 to 120.0
Raindrop Size (mm) At sizes less than 1.0mm, trueSKY will use a Submillimetric Light Scattering Approximation to adjust the spectual output. 0.001 to 100.0
Variable Definition Value
Strength Adjusts the strength the rainbow. 0.0 to 1.0
Rain Streaks Adjusts the strength the rainbow. 0.0 to 1.0

Note: Both Rain Strength and Rain Streaks must be greated than 0 for rainbows to be generated.
