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 |
