 A Virtual Laboratory is not a physical segment in Visual3D but is equivalent to a physical segment to the effect that it has a Segment Coordinate System that can be used to represent the laboratory (or other objects) and has an associated surface model that can be animated as part of the scene. A typical use of the Virtual Laboratory is to represent the floor so that motion capture markers can be projected onto the floor.
-**Note:** A typical use of the Virtual laboratory is for creating [[Visual3D:Documentation:Pipeline:Model_Based_Data_Commands:Joint_Angle#Joint_Angle_Normalization|Normalized Joint Angles and Normalized Segment Angles]].

 Below is a straightforward virtual lab that has a specified constant orientation.
