Bump Map
This filter uses a source object to define a bump pattern which can be used to deform
an object, with parameters to control the amount of distortion. You can use any image,
movie, or shape as the source object.
When this filter is initially applied, Bump Map behaves as if there were a black image
applied to the Map Image well, which does not distort the target image at all.
To learn how to add an object to the Map Image well, see Source Well .
This filter causes rasterization in 3D groups.
