QPickTriangleEvent Class

(Qt3DRender::QPickTriangleEvent)

The QPickTriangleEvent class holds information when a triangle is picked. More...

Header: #include <QPickTriangleEvent>
qmake: QT += 3drender
Since: Qt 5.7
Instantiated By: PickTriangleEvent
Inherits: Qt3DRender::QPickEvent

This class was introduced in Qt 5.7.

Properties

Public Functions

QPickTriangleEvent(const QPointF &position, const QVector3D &worldIntersection, const QVector3D &localIntersection, float distance, uint triangleIndex, uint vertex1Index, uint vertex2Index, uint vertex3Index)
QPickTriangleEvent()
uint triangleIndex() const
QVector3D uvw() const
uint vertex1Index() const
uint vertex2Index() const
uint vertex3Index() const

Detailed Description

When QPickingSettings::pickMode() is set to QPickingSettings::TrianglePicking, the signals on QObjectPicker will carry an instance of QPickTriangleEvent.

This contains the details of the triangle that was picked.

Note: In the case of indexed rendering, the point indices are relative to the array of coordinates, not the array of indices.

See also QPickingSettings, QPickEvent, QObjectPicker, and QAttribute.

QPickTriangleEvent::QPickTriangleEvent(const QPointF &position, const QVector3D &worldIntersection, const QVector3D &localIntersection, float distance, uint triangleIndex, uint vertex1Index, uint vertex2Index, uint vertex3Index)

*

QPickTriangleEvent::QPickTriangleEvent Constructs a new QPickEvent with the given parameters * position, * worldIntersection, * localIntersection, * distance, * triangleIndex, * vertex1Index, * vertex2Index and * vertex3Index

QPickTriangleEvent::QPickTriangleEvent()

Constructs a new QPickEvent.

uint QPickTriangleEvent::triangleIndex() const

QPickTriangleEvent::triangleIndex Returns the index of the picked triangle

Note: Getter function for property triangleIndex.

QVector3D QPickTriangleEvent::uvw() const

Returns the 3D coordinates u,v, and w.

Note: Getter function for property uvw.

uint QPickTriangleEvent::vertex1Index() const

QPickTriangleEvent::vertex1Index Returns the index of the first point of the picked triangle

Note: Getter function for property vertex1Index.

uint QPickTriangleEvent::vertex2Index() const

QPickTriangleEvent::vertex2Index Returns the index of the second point of the picked triangle

Note: Getter function for property vertex2Index.

uint QPickTriangleEvent::vertex3Index() const

QPickTriangleEvent::vertex3Index Returns index of third point of picked triangle

Note: Getter function for property vertex3Index.
