enum QRayCasterHit:: HitType

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
