Specifies type of hit that was returned. This is controlled using QPickingSettings .
| 常量 | 值 | 描述 |
|---|---|---|
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 |

注意： Getter function for property entityId.
Returns the coordinates of the intersection point in the entity's coordinate system
注意： Getter function for property localIntersection.
Returns the index of the picked primitive
注意： Getter function for property primitiveIndex.
Returns the type of the hit
注意： getter 函数对于特性 type。
Returns the index of the first vertex of the picked primitive
注意： Getter function for property vertex1Index.
Returns the index of the second vertex of the picked primitive
注意： Getter function for property vertex2Index.
Returns the index of the third vertex of the picked primitive
注意： Getter function for property vertex3Index.
Returns the coordinates of the intersection point in the model's coordinate system
注意： Getter function for property worldIntersection.
