Methods
 NameDescription
Public methodAlmostEqualDetermines whether this transformation and the specified transformation are the same within the tolerance (1.0e-09).
Public methodStatic memberCode exampleCreateReflection Creates a transform that represents a reflection across the given plane.
Public methodStatic memberCreateRotation Creates a transform that represents a rotation about the given axis at (0, 0, 0).
Public methodStatic memberCreateRotationAtPoint Creates a transform that represents a rotation about the given axis at the specified point.
Public methodStatic memberCreateTranslation Creates a transform that represents a translation via the specified vector.
Public methodDisposeCauses the object to release immediately any resources it may be utilizing.
(Inherited from APIObject)
Public methodEqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
Public methodGetHashCodeServes as the default hash function.
(Inherited from Object)
Public methodGetTypeGets the Type of the current instance.
(Inherited from Object)
Public methodMultiplyMultiplies this transformation by the specified transformation and returns the result.
Public methodOfPointApplies the transformation to the point and returns the result.
Public methodOfVectorApplies the transform to the vector
Public methodScaleBasisScales the basis vectors of this transformation and returns the result.
Public methodScaleBasisAndOriginScales the basis vectors and the origin of this transformation and returns the result.
Public methodToStringReturns a string that represents the current object.
