The function is based on the gaussian function, but it allows to modify the position of focus and the strength of falloff. Use the published properties //IntensityFocus// and //IntensityExp// or the //AlphaIntensityFocus// and //AlphaIntensityExp// properties to control behaviour.| | |{{:1.2.0:volmesh-distmeth-gaussian.jpg|}}|rcdFocused|f(x) = 1.0f - ((x - IntensityFocus)² * IntensityExp)|Smooth value intensity computation on a focused area, where values closer to the IntensityFocus position are more intense than values more far away.
