QPickTriangleEvent Class

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.

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.
