I'm trying to use data returned from the RoomCaptureSession delegate to draw four corners of a door in SceneKit. The CapturedRoom.Surface class has Dimensions and Transform members. I was told in the WWDC 2022 RoomPlan Slack lounge: "You can use transform and dimensions parameters to draw lines. The 4 corners can be inferred from those 2 parameters: the first column of the transform is the "right" vector, and second is the "up" vector. The fourth column is the position of the wall/door/opening/window/object Combining those unit vectors with the dimensions vector will give you the corners." So I think this is a basic vector question. I'm not sure what is meant by "Combining those unit vectors with the dimensions vector". I've tried a few things, but I'm not sure how to go about this.

I want to use room plan api alongside with scene reconstruction api at the same time. but doesn't seem to work
