[read-only] distance : float

This property holds the distance between the pick origin and the hit position i.e. the length of the ray. In the case of using viewport coordinates for picking the pick origin will be the active camera's position.

[read-only, since 6.5] instanceIndex : int

This property holds the index in the instance table for the case where the pick hit an instance of an instanced model.

该特性在 Qt 6.5 引入。

[read-only] normal : vector3d

This property holds the normal of the face that was hit in local coordinate space.

[read-only] objectHit : Model

This property holds the model object hit by the pick.

[read-only] position : vector3d

This property holds the scene position of the hit in local coordinate space.

[read-only] sceneNormal : vector3d

This property holds the normal of the face that was hit in scene coordinate space.

[read-only] scenePosition : vector3d

This property holds the scene position of the hit.

[read-only] uvPosition : vector2d

This property holds the UV position of the hit. The UV position is calculated as the normalized local x and y coordinates of the hit point relative to the bounding volume. Useful for further picking against an offscreen-rendered object.
