Detailed Description

Geometric class.

Library: display

The IlvDeltaPoint class is used to create a vector. A vector is an oriented displacement in a two-dimensional coordinate system.

Constructor & Destructor Documentation

IlvDeltaPoint::IlvDeltaPoint	(	IlvDeltaPos	x = 0,
		IlvDeltaPos	y = 0
	)

Constructor.

Initializes a vector with defined coordinates.

Parameters

Parameters

newX	The x offset.

void IlvDeltaPoint::setY

(

IlvDeltaPos

yy

)

void IlvDeltaPoint::translate	(	IlvDeltaPos	x,
		IlvDeltaPos	y
	)

Translates a vector.

Uses the delta parameters to modify the current value of the vector.

Parameters

x	The x offset.
y	The y offset.
