Class Entity124_TransformationMatrix

  • public class Entity124_TransformationMatrix
extends Entity
    TRANSFORMATION MATRIX ENTITY - This allows translation and rotation to be applied to other entities. This is used to define alternate coordinate systems for definition and viewing. The transformation matrix entity transforms three-row column vectors by means of matrix multiplication and then a vector addition. This entity can be considered as an "operator" entity in that it starts with the input vector, operates on it as described above, and produces the output vector.

    This entity, when read from an IGES file, is converted to a GTransform object. This entity type can not be written out to an IGES file.
