class PySide2.Qt3DRender.Qt3DRender. QRayCasterHit ¶

PySide2.Qt3DRender.Qt3DRender.QRayCasterHit(type, id, distance, localIntersect, worldIntersect, primitiveIndex, v1, v2, v3)

PySide2.Qt3DRender.Qt3DRender.QRayCasterHit(other)

参数

• type – HitType

• v1 – uint

• v2 – uint

• v3 – uint

• primitiveIndex – uint

• id – QNodeId

• distance – float

• other – QRayCasterHit

• localIntersect – QVector3D

PySide2.Qt3DRender.Qt3DRender.QRayCasterHit. HitType ¶

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

常量	描述
Qt3DRender.QRayCasterHit.TriangleHit	The picked primitive was a triangle and the vertex indices refer to the three points making up the triangle
Qt3DRender.QRayCasterHit.LineHit	The picked primitive was a line segment, and the first two vertices refer to the two points making up the line
Qt3DRender.QRayCasterHit.PointHit	The picked primitive was a single point; all 3 vertex indices will be undefined
Qt3DRender.QRayCasterHit.EntityHit	Only the bounding volume was considered; the primitive and vertex indices will be undefined
