Functional Details

input	is a field whose data dependency on one component is to be changed to dependency on another component.
dependency	is the output dependency desired and must be "positions" or "connections."

If you are changing the dependency from "positions" to "connections," all components that are dependent on "positions" (but do not contain references to that or any other component, such as colors, data, and normals) are changed to "connections" dependency. The Post module uses an average of the vertex values for each connection element to determine the new value for the component.

Similarly, when changing from connection dependence to position dependence, the Post module associates with a vertex the average of the values for each connection touching that vertex.

Components

Creates a new component for each input component that is either dependent on connections if dependency is "positions" or that is dependent on positions if the dependency is "connections." The dependencies of the new components are set to dependency.
