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, and QObjectPicker.

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.
