au3Irr2 Function Reference
_IrrSetFogSet the properties of fog in the scene
#Include <au3Irrlicht2.au3>
_IrrSetFog($i_Red, $i_Green, $i_Blue, $i_FogType, $f_FogStart, $f_FogEnd, $f_Density = 0.025)
Parameters
| $i_Red, $i_Green, $i_Blue | Define colour of the fog (0-255). Should be set to the same colour as the scene sky so the scene fogs out nicely into nothing. |
| $i_FogType | Defines how the fog is calculated: $IRR_LINEAR_FOG - computed as [end - distance / end - start], density value is not used. $IRR_EXPONENTIAL_FOG - computed as [1 / (2.718^(distance * densitiy))], both start and end values are not used. |
| $f_FogStart, $f_FogEnd | Distances at which the fog starts and at which it reaches its maximum density. Values are ignored for exponential fog. |
| $f_Density | [optional] Determines how quickly the exponential change takes place, with value from 0 to 1. Example: A value of 0.025 equals 20% visibility at 50 units distance. Value is ignored for linear fog. |
