AVL.ReducePath(AvlNet.Path, float, AvlNet.Path, AvlNet.Path[])

Reduces the number of points in a path preserving its shape with the specified precision.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void ReducePath(
	AvlNet.Path inPath,
	float inMaxDistance,
	out AvlNet.Path outPath,
	out AvlNet.Path[] diagIntermediatePaths
)

Parameters

inPath
Type: AvlNet.Path
Input path
inMaxDistance
Type: System.Single
Maximum distance between (possibly removed in the process) characteristic point of the input path and the output path.
outPath
Type: AvlNet.Path
Reduced path
diagIntermediatePaths
Type: AvlNet.Path
Intermediate results on all levels of recursion of the Ramer algorithm

Description

The operation removes some of the characteristic points of the input path preserving its shape with the selected precision. The algorithm guarantees that each of the removed characteristic points lies within the inMaxDistance distance from the resulting path.

The operation works with open and closed paths as well.

Examples

ReducePath run on the sample path array with inMaxDistance = 0.5.

ReducePath run on the sample path array with inMaxDistance = 5.
