Method Summary

void	fillDistanceAttenuation(float innerRadius, float maxConstantGain, float unitDistance, float unitGain, int curveType, Point2f[] distanceAttenuation)
void	fillDistanceAttenuation(float unitDistance, float unitGain, Point2f[] distanceAttenuation) Fill a Distance Attenuation array recommend that the distance attenuation Point2f array is defined to be allocated to be 10 for DOUBLE_DISTANCE_HALF_GAIN - since 1/(2^10) exceeds 1/1000 scale that is agreed to be affective zero gain First method assumes that: type is half gain for every double of distance inner radius is 0.0 but region between 0th and 1st elements is constant since gains for these two elements are the same min gain approches zero.
