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 |
Returns the distance between the origin of the ray and the intersection point
Returns a pointer to the entity that was hit
Returns the id of the entity that was hit
Returns the coordinates of the intersection point in the entity's coordinate system
Returns the index of the picked primitive
Returns the type of the hit
Returns the index of the first vertex of the picked primitive
Returns the index of the second vertex of the picked primitive
Returns the index of the third vertex of the picked primitive
Returns the coordinates of the intersection point in the model's coordinate system
