Qt3DRender.QPickingSettings ¶

概要 ¶

详细描述 ¶

The picking settings determine how the entity picking is handled. For more details about entity picking, see QObjectPicker and QRayCaster component documentation.

当使用 QObjectPicker components, picking is triggered by mouse events.

当使用 QRayCaster or QScreenRayCaster components, picking can be explicitly triggered by the application.

In both cases, a ray will be cast through the scene to find geometry intersecting the ray.

参数

parent – QNode

PySide2.Qt3DRender.Qt3DRender.QPickingSettings. PickMethod ¶

Specifies the picking method.

常量	描述
Qt3DRender.QPickingSettings.BoundingVolumePicking	An entity is considered picked if the picking ray intersects the bounding volume of the entity (default).
Qt3DRender.QPickingSettings.TrianglePicking	An entity is considered picked if the picking ray intersects with any triangle of the entity’s mesh component.
Qt3DRender.QPickingSettings.LinePicking	An entity is considered picked if the picking ray intersects with any edge of the entity’s mesh component.
Qt3DRender.QPickingSettings.PointPicking	An entity is considered picked if the picking ray intersects with any point of the entity’s mesh component.
Qt3DRender.QPickingSettings.PrimitivePicking	An entity is considered picked if the picking ray intersects with any point, edge or triangle of the entity’s mesh component.

PySide2.Qt3DRender.Qt3DRender.QPickingSettings. PickResultMode ¶

Specifies what is included into the picking results.

常量	描述
Qt3DRender.QPickingSettings.NearestPick	Only the nearest entity to picking ray origin intersected by the picking ray is picked (default).
Qt3DRender.QPickingSettings.AllPicks	All entities that intersect the picking ray are picked.
Qt3DRender.QPickingSettings.NearestPriorityPick	Selects the entity whose object picker has the highest value. If several object pickers have the same priority, the closest one on the ray is selected.
