Detailed Description

The Triangle class represents a triangle in three dimensional space.

Mostly this is a data class storing the vertices and is easy copyable. Also, some helper functions are implemented.

Constructor & Destructor Documentation

Triangle::Triangle

(

)

Creates a new degenerated Triangle, with all points in (0, 0, 0).

Triangle::Triangle	(	const QVector3D &	a,
		const QVector3D &	b,
		const QVector3D &	c
	)

Creates a new Triangle, with specified points. It is expected, that points a, b and c are ordered counter clock wise.

Parameters

a	First vertex.
b	Second vertex.
c	Third vertex.

Triangle::Triangle

(

const Triangle &

triangle

)

Creates a new Triangle with data copied from given triangle.

Parameters

triangle

The Triangle, that will be copied.

Triangle::~Triangle

(

const

Returns normal of triangle. The vertices a(), b() and c() ordered counter clockwise are expected to describe outer side of triangle.

Returns

Triangle & Triangle::operator=

(

const Triangle &

triangle

)

QVector3D Triangle::reflect

(

const QVector3D &

incidentVector

)

const

Reflects incoming ray at outer side of triangle.

Parameters

incidentVector

The vector that will be reflected.

Returns

Reflected vector.

void Triangle::setA

(

const QVector3D &

a

)

void Triangle::setB

(

const QVector3D &

b

)

void Triangle::setC

(

c

)

QList< QVector3D > Triangle::vertices

(

)

const

Convenience method. All vertices are returned in QList.

Returns

QList of vertices. Containing a(), b() and c() in this order.
