AVL.ResizeVector

Lengthens or shortens a vector preserving its direction.

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax

C++
C#
 
public static void ResizeVector
(
	AvlNet.Vector2D inVector,
	float inNewLength,
	out AvlNet.Vector2D outVector
)

Parameters

Name Type Range Default Description
inVectorAvlNet.Vector2D
inNewLengthfloat<0.0f, INF>1.0fDefault value: 1.0f.
outVectorAvlNet.Vector2D

Description

Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when a zero vector is given on input.

Examples

ResizeVector performed on a vector (red one) with DeltaX = 0, DeltaY = 10 with parameter inNewLength = 5. outVector returns vector (blue one)
