Class: RigidBodyTransformationMatrix
A 4x4 transformation matrix, to be used explicitly for rigid body transformations. The
transformation matrix is in column-major format. Elements 0-3 represent, respectively,
the x-components of the X axis, Y axis, Z axis, and translation with respect to global.
Identically, elements 4-7 represent the y components and elements 8-11 the z components.
Elements 2-15, per rigid-body requirements, are expected to be [0.0, 0.0, 0.0, 1.0].
The ability to piecewise set rotation and translation components precludes the option of
validating the matrix data at every operation. Thus, these values ***must*** be checked
before the data is used.
The class `Ansys.ACT.Common.SimpleTransform` provides a simplified mechanism for working
with rigid body transformations and getting a `RigidBodyTransformationMatrix` object.
