Detailed Description

QScreenRayCaster can be used to perform ray casting tests by specifying coordinates in screen space, which will be used to construct an actual 3D ray between the near and far planes.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property positionᅟ: QPoint

Holds the screen space position used to compute the actual 3D ray for intersection tests.

Note: the coordinates will be used for every available render surface as long as they are in the valid range.

Access functions:

• position()

• setPosition()

• Signal positionChanged()
