Detailed Description¶

The 3d ray is defined by its origin, direction and length. It will be affected by the transformations applied to the entity it belongs to.

Ray casting tests will be performed every frame as long as the component is enabled. The hits property will be updated with the list of intersections.

Note

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

property directionᅟ: QVector3D¶

Holds the direction of the 3D ray. This should be a unit vector.

Access functions:

direction()
setDirection()
Signal directionChanged()

property lengthᅟ: float¶

Holds the length of the 3D ray.

Access functions:

length()
setLength()
Signal lengthChanged()

property originᅟ: QVector3D¶

Holds the origin of the 3D ray in local coordinates.

Access functions:

origin()
setOrigin()
Signal originChanged()

__init__([parent=None])¶

Parameters:: parent – QNode

direction()¶

Return type:: QVector3D

See also

setDirection()

Getter of property directionᅟ .

directionChanged(direction)¶

Parameters:: direction – QVector3D

Notification signal of property directionᅟ .

length()¶

Return type:: float

See also

setLength()

Getter of property lengthᅟ .

lengthChanged(length)¶

Parameters:: length – float

Notification signal of property lengthᅟ .

origin()¶

Return type:: QVector3D

See also

setOrigin()

Getter of property originᅟ .

originChanged(origin)¶

Parameters:: origin – QVector3D

Notification signal of property originᅟ .

pick(origin, direction, length)¶

Parameters:

origin – QVector3D
direction – QVector3D
length – float

Return type:

.list of Qt3DRender.QRayCasterHit

setDirection(direction)¶

Parameters:: direction – QVector3D

See also

direction()

Setter of property directionᅟ .

setLength(length)¶

Parameters:: length – float

Sets the length of the ray to length.

If the value is less than or equal to zero, the ray is concidered to be infinite.

length()

Setter of property lengthᅟ .

setOrigin(origin)¶

Parameters:: origin – QVector3D

See also

origin()

Setter of property originᅟ .

trigger()¶

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

trigger(origin, direction, length)

Parameters:

origin – QVector3D
direction – QVector3D
length – float

Convenience method to set the ray details origin, direction, and length, and enable the component to trigger tests.
