Table 6.137 — DRM_Local_4x4

Property

Description

Class

  • <DRM Local 4x4>

Superclass

Subclass

  • None.

Definition

An instance of this DRM class specifies a 4×4 matrix that is used to scale, orient, and position DRM objects in the scope of its aggregate <DRM LSR Transformation> instance. The direction of rotation is determined by the right-hand rule. The translation parameters are always in the rightmost column of the matrix.

Since a <DRM Local 4x4> instance only appears as a component of a <DRM LSR Transformation> instance and a <DRM LSR Transformation> instance only appears in the scope of an LSR SRF, the DRM objects to which a <DRM Local 4x4> instance is applied are always specified in an LSR SRF.

The matrix multiplication order is defined by w = M × v, where M is the matrix of the <DRM Local 4x4> instance, v is the original location vector, and w is the resulting location vector.

The matrix field specifies a standard 4 × 4 transformation matrix.
