Detailed Description
Qt3DRender::QRayCasterHit contains the details of a successful hit when casting a ray through a model using a Qt3DRender::QRayCaster or Qt3DRender::QScreenRayCaster component.
See also Qt3DRender::QRayCaster, Qt3DRender::QScreenRayCaster, and Qt3DRender::QPickingSettings.
Member Type Documentation
enum QRayCasterHit::HitType
Specifies type of hit that was returned. This is controlled using QPickingSettings.
| Constant | Value | Description |
|---|---|---|
Qt3DRender::QRayCasterHit::TriangleHit | 0 | The picked primitive was a triangle and the vertex indices refer to the three points making up the triangle |
Qt3DRender::QRayCasterHit::LineHit | 1 | The picked primitive was a line segment, and the first two vertices refer to the two points making up the line |
Qt3DRender::QRayCasterHit::PointHit | 2 | The picked primitive was a single point; all 3 vertex indices will be undefined |
Qt3DRender::QRayCasterHit::EntityHit | 3 | Only the bounding volume was considered; the primitive and vertex indices will be undefined |
Member Function Documentation
float QRayCasterHit::distance() const
Returns the distance between the origin of the ray and the intersection point
Note: Getter function for property distance.

Returns a pointer to the entity that was hit
Note: Getter function for property entity.
Qt3DCore::QNodeId QRayCasterHit::entityId() const
Returns the id of the entity that was hit
Note: Getter function for property entityId.
QVector3D QRayCasterHit::localIntersection() const
Returns the coordinates of the intersection point in the entity's coordinate system
Note: Getter function for property localIntersection.
uint QRayCasterHit::primitiveIndex() const
Returns the index of the picked primitive
Note: Getter function for property primitiveIndex.
Qt3DRender::QRayCasterHit::HitType QRayCasterHit::type() const
Returns the type of the hit
Note: Getter function for property type.
uint QRayCasterHit::vertex1Index() const
Returns the index of the first vertex of the picked primitive
Note: Getter function for property vertex1Index.
uint QRayCasterHit::vertex2Index() const
Returns the index of the second vertex of the picked primitive
Note: Getter function for property vertex2Index.
uint QRayCasterHit::vertex3Index() const
Returns the index of the third vertex of the picked primitive
Note: Getter function for property vertex3Index.
QVector3D QRayCasterHit::worldIntersection() const
Returns the coordinates of the intersection point in the model's coordinate system
