I'm learning from a tutorial online on ARKit to place an object on a plane.
boxNode.position = SCNVector3(hitResult.worldTransform.columns.3.x,hitResult.worldTransform.columns.3.y + Float(boxGeometry.height/2), hitResult.worldTransform.columns.3.z)
he uses the code above to place it at the location where you tap on the screen
what does this mean:
hitResult.worldTransform.columns.3.x
why is it columns.3 and not columns.0 for example?
