Replaces the geometry of a feature with a two-dimensional representation of the feature's shadow.
Output features with replaced shadow geometries.
Features with null geometries are rejected.
Overhead Shadow: The shadows are obtained from a light source directly above the features. The shadows will have a Z coordinate of 0.
Drop Shadow: The shadows are obtained from a light source located in a direction specified by the X, Y, Z parameters. The shadows will have a Z coordinate of 0.
Perpendicular Shadow: The shadows are obtained from a light source located in a direction specified by the X, Y, Z parameters, but are cast onto a plane perpendicular to the direction of the light source. Each feature's shadow is located near the original feature, so the shadows may not all lie on the same plane.
Coordinates representing the direction of the light source projecting the shadow. The light source is considered to be an infinite distance away.
The Z coordinate cannot be 0.
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.
