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.

Member Type Documentation

enum QRayCasterHit::HitType

Specifies type of hit that was returned. This is controlled using QPickingSettings.

ConstantValueDescription
Qt3DRender::QRayCasterHit::TriangleHit0The picked primitive was a triangle and the vertex indices refer to the three points making up the triangle
Qt3DRender::QRayCasterHit::LineHit1The picked primitive was a line segment, and the first two vertices refer to the two points making up the line
Qt3DRender::QRayCasterHit::PointHit2The picked primitive was a single point; all 3 vertex indices will be undefined
Qt3DRender::QRayCasterHit::EntityHit3Only 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.

Qt3DCore::QEntity *QRayCasterHit::entity() const

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

Note: Getter function for property worldIntersection.
