Class Name: World Transformation

Superclass - <Transformation>

Subclasses

Definition

An instance of this DRM class is a <Transformation>, specified by a <Location> and a <World 3x3>, used to transform an object defined in an LSR spatial reference frame into another spatial reference frame (usually, but not always, a non-LSR spatial reference frame).

A <World Transformation> is either

1. defined in a non-LSR spatial reference frame, then used to instance an LSR <Model> into the non-LSR spatial reference frame, or
2. defined within an LSR spatial reference frame (SRF_1), and then used to instance a <Model> embedded within another LSR spatial reference frame (SRF_2) into SRF_1, in a way that maintains the conformality of any <Locations> in the <Model>.

Example

1. Used when instancing a house onto geodetic terrain (defined by latitude and longitude). This allows the <Location> to position the house and the <World 3x3> to rotate and scale the house. See <Transformation> for examples.
