Definition |
An object of this DRM class is a <DRM Transformation>, specified by a <DRM Location> and a 3x3 matrix, is 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 <DRM World Transformation> is a transformation that is either: a. defined in a non-LSR spatial reference frame, and is then used to instance an LSR <DRM Model> into the non-LSR spatial reference frame, or b. defined within a LSR spatial reference frame (SRF1), and is then used to instance a <DRM Model> embedded within another LSR spatial reference frame (SRF2), in a way that maintains the conformality of any <DRM Location>s in the <DRM Model>. |

|
Example(s) |
· Used when instancing a house onto geodetic terrain (defined by latitude and longitude). This allows the location to position the house and the 3X3 to rotate and scale the house. See <DRM Transformation> for examples. |
