Variables ==================== 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 anti-solar/anti-lunar 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 spectral 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 greater than 0 for rainbows to be generated.
