Record TRayCollisionNode

Colliding object.

Position, in local coordinate system of this 3D object, of the picked 3D point.

If the ray hit empty space (Triangle field is Nil), then this is undefined. Such case may occur because, once TCastleTransform handles TCastleTransform.PointingDevicePress, we make sure to inform it about PointingDeviceMove and PointingDeviceRelease, regardless if ray still hits this TCastleTransform instance.

Triangle that was hit. This triangle is always a part of Item.

If the ray hit empty space then this is Nil. Such case may occur because, once TCastleTransform handles TCastleTransform.PointingDevicePress, we make sure to inform it about PointingDeviceMove and PointingDeviceRelease, regardless if ray still hits this TCastleTransform instance.

May also be Nil if RayCollision implementation for the 3D object simply left it Nil. For example,

• If the collision occured with a TCastleSceneCore with TCastleSceneCore.PreciseCollisions then this triangle is set.

• If the collision occured merely with a TCastleTransform bounding box, the triangle is left as Nil.

Ray used to cause the collision, in the parent coordinate system of this TCastleTransform. RayDirection is not necessarily normalized!
