Class: QgsRay3D¶

A representation of a ray in 3D.

A ray is composed of an origin point (the start of the ray) and a direction vector.

Added in version 3.18.

Methods

`angleToPoint`	Returns the angle between the ray and the vector from the ray's origin and the point point
`direction`	Returns the direction of the ray see `setDirection()`
`directionInversed`	Returns a vector with the direction components inversed ( 1/x, 1/y, 1/z) This can be used as an optimization when used in intersection logic.
`isInFront`	Checks whether the point is in front of the ray
`origin`	Returns the origin of the ray
`point`	Returns the point along the ray with the specified distance from the ray's origin
`projectedDistance`	Returns the distance of the projection of a point to the ray
`projectedPoint`	Returns the projection of the point on the ray (which is the closest point of the ray to point)
`setDirection`	Sets the direction of the ray
`setOrigin`	Sets the origin of the ray

direction(self) → QVector3D[source]¶

Returns the direction of the ray see setDirection()

Return type:: QVector3D

directionInversed(self) → QVector3D[source]¶

Returns a vector with the direction components inversed ( 1/x, 1/y, 1/z) This can be used as an optimization when used in intersection logic. see direction()
