Detailed Description

The QPickTriangleEvent class holds information when a triangle is picked

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.

Member Function Documentation

QPickTriangleEvent::QPickTriangleEvent()

Constructs a new QPickEvent.

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(const QPointF &position, const QVector3D &worldIntersection, const QVector3D &localIntersection, float distance, uint triangleIndex, uint vertex1Index, uint vertex2Index, uint vertex3Index, Qt3DRender::QPickEvent::Buttons button, int buttons, int modifiers, const QVector3D &uvw)

Default constructs an instance of QPickTriangleEvent.

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
