RandomWeightedPoint

function TTriangle.RandomWeightedPoint(from: TPoint; weight: Single = 10.0; bias: Single=1): TPoint;
function TPolygon.RandomWeightedPoint(from: TPoint; weight: Single = 10.0; bias: Single=1): TPoint;
function TQuad.RandomWeightedPoint(from: TPoint; weight: Single = 10.0; bias: Single=1): TPoint;
function TBox.RandomWeightedPoint(from: TPoint; weight: Single = 10.0; bias: Single=1): TPoint;

Generates a random point within the TTriangle, drawn towards a from point.

Parameters:

  • from: The point towards which the distribution is drawn.

  • weight: Controls the strength of attraction towards the from (higher values = stronger attraction).

    • weight = 0 gives a uniform distribution.

  • bias: Introduces a Gaussian spread around the from (higher values = wider spread).

    • bias = 0 gives a purely weighted distribution towards the from.

Should expose weight and bias to the user if used as mouse distribution method. weight of 10 might be a little high.

TQuad.RandomSkewedPoint

function TQuad.RandomSkewedPoint(from: TPoint; force: Double = 0.35): TPoint;

Generates a random point within the bounds of the TQuad, the point generated is skewed towards towards the from-point. The last parameter force defines how much the generated point is to be skewed towards or away from from - Expects value in the range 0..2

  • force = 0: Result weighs heavily towrads the edge closest to From

  • force = 1: Result in the middle of box is most common

  • force = 2: Result weighs heavily towrads the edge furthest away from From

TBox.RandomSkewedPoint

function TBox.RandomSkewedPoint(from: TPoint; force: Double = 0.35): TPoint;

Generates a random point within the bounds of the TBox, the point generated is skewed towards towards the from-point. The last parameter force defines how much the generated point is to be skewed towards or away from from - Expects value in the range 0..2

  • force = 0: Result weighs heavily towrads the edge closest to From

  • force = 1: Result in the middle of box is most common

  • force = 2: Result weighs heavily towrads the edge furthest away from From
