class PySide2.Qt3DRender.Qt3DRender.QScreenRayCaster([parent=None])

Parameters:

parent – PySide2.Qt3DCore.Qt3DCore.QNode

PySide2.Qt3DRender.Qt3DRender.QScreenRayCaster.position()

Return type:

PySide2.QtCore.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.

PySide2.Qt3DRender.Qt3DRender.QScreenRayCaster.positionChanged(position)

Parameters:

position – PySide2.QtCore.QPoint

PySide2.Qt3DRender.Qt3DRender.QScreenRayCaster.setPosition(position)

Parameters:

position – PySide2.QtCore.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.

PySide2.Qt3DRender.Qt3DRender.QScreenRayCaster.trigger()

Convenience method to enable the component and trigger tests using the current coordinate value.

PySide2.Qt3DRender.Qt3DRender.QScreenRayCaster.trigger(position)

Parameters:

position – PySide2.QtCore.QPoint

Convenience method to set the coordinate value position and enable the component to trigger tests.
