VectorDirection

Header:	FIL.h
Namespace:	fil
Module:	FoundationLite

Computes the direction angle of a vector as an angle in range the from 0 to 360.

Syntax

void fil::VectorDirection
(
	const fil::Vector2D& inVector,
	float& outDirection
)

Parameters

	Name	Type	Default	Description
	inVector	const Vector2D&
	outDirection	float&

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

VectorDirection performed on a vector with parameters: DeltaX = 10, DeltaY = 10.
outDirection returns 45.
