Overview
Some Resources (like Move Object Resource and Move User Resource ) take a “Position” parameter. Position can either be Relative or Fixed. This document describes the difference between these two position types.
Fixed Position
The main difference between Fixed and Relative Positions is that Fixed Position uses the World’s coordinate system to compute offsets and rotation. A Fixed Position takes an optional anchor.
Fixed Position Without an Anchor
Field Name | Description |
|---|---|
Position (required) | Object is positioned at the World X,Y,Z coordinates. |
Rotation (optional) | If set, Object is rotated to the given rotation based on World coordinates (e.g. a rotation of Y=90 will look “East”). If not set, the Object’s rotation will not change. |
Fixed Position With an Anchor
Field Name | Description |
|---|---|
Position (required) | Object is offset from the anchor’s position using world X,Y,Z coordinates. For example, Z=3 will offset the Object 3m to the “north” of the anchor regardless of the rotation of the anchor. |
Rotation (optional) | If set, Object is rotated to the given rotation based on World coordinates (e.g. a rotation of Y=90 will look “East”). If not set, the Object’s rotation will not change. Note that the object’s Rotation is not impacted by the rotation of the anchor for Fixed Position. |
