The QPickTriangleEvent class holds information when a triangle is picked. 更多...
| 頭： | #include <QPickTriangleEvent> |
| qmake: | QT += 3drender |
| Since: | Qt 5.7 |
| 實例化： | PickTriangleEvent |
| 繼承： | Qt3DRender::QPickEvent |
該類在 Qt 5.7 引入。
|
|
| 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 |
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.
注意： In the case of indexed rendering, the point indices are relative to the array of coordinates, not the array of indices.

QPickTriangleEvent::QPickTriangleEvent 構造新的 QPickEvent with the given parameters * position , * worldIntersection , * localIntersection , * distance , * triangleIndex , * vertex1Index , * vertex2Index 和 * vertex3Index
構造新的 QPickEvent .
QPickTriangleEvent::triangleIndex Returns the index of the picked triangle
注意： Getter function for property triangleIndex.
Returns the 3D coordinates u,v, and w.
注意： Getter function for property uvw.
QPickTriangleEvent::vertex1Index Returns the index of the first point of the picked triangle
注意： Getter function for property vertex1Index.
QPickTriangleEvent::vertex2Index Returns the index of the second point of the picked triangle
注意： Getter function for property vertex2Index.
QPickTriangleEvent::vertex3Index Returns index of third point of picked triangle
注意： Getter function for property vertex3Index.
