ConvertToEquidistantPath

Header:	AVL.h
Namespace:	avl
Module:	FoundationBasic

Creates a new path whose characteristic points lie on the input path, but are equally spaced.

Syntax

void avl::ConvertToEquidistantPath
(
	const avl::Path& inPath,
	float inStep,
	avl::EquidistanceType::Type inEquidistanceType,
	avl::Path& outPath
)

Parameters

Name	Type	Range	Default	Description
inPath	const Path&			Input path
inStep	float	0.0 -	1.0f	Requested distance between consecutive points
inEquidistanceType	EquidistanceType::Type			Defines how the distance is measured
outPath	Path&			Output path

Description

The operation follows a path from its beginning to the end, reselecting its characteristic points every inStep pixels. Note that this operation can significantly change the shape of a path, especially when the inStep value is relatively big. The output path's last point is mostly not the same as the input path's last point, because it would lead to last output path's segment being too short.

To reduce the number of points in a path preserving its shape, one can use ReducePath filter.

Examples

ConvertToEquidistantPath run on the sample path with inStep = 10 and inEquidistanceType = OutputPathEquidistance.

ConvertToEquidistantPath run on the sample path with inStep = 100 and inEquidistanceType = OutputPathEquidistance.
