ResizeVector


Header: FIL.h
Namespace: fil
Module: FoundationLite

Lengthens or shortens a vector preserving its direction.

Syntax

C++
C#
 
void fil::ResizeVector
(
	const fil::Vector2D& inVector,
	float inNewLength,
	fil::Vector2D& outVector
)

Parameters

Name Type Range Default Description
Input value inVector const Vector2D&
Input value inNewLength float 0.0 - 1.0f
Output value outVector Vector2D&

In-place Processing

This function supports in-place data processing - you can pass the same reference to inVector and outVector

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)
