x' = C + E(x-A) - F(y-B) + G((x-A)^2 - (y-B)^2) - 2H(x-A)(y-B)
y' = D + E(y-B) + F(x-A) + H((x-A)^2 - (y-B)^2) + 2G(x-A)(y-B)
z' = z + I
Each of the parameters may either be entered as a number, or can be taken from the value of a feature attribute by selecting the attribute name from the pull down list.
This transformation is non-linear. Thus, to maintain the integrity of the data, we only perform transformations on the points defining geometries. For example, a 4-point quadrilateral polygon will remain a 4-point polygon after transformation, although a pure transformation would convert its lines into curves. If curve approximates from lines are desired, use a Densifier before this transformer.
Due to the non-linear nature of the transformation, true 3D geometries (such as Box and EnclosedSurface) are not supported by this transformer. All true-3D geometries are passed to the Invalid port.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
