6  * NAME: GU_SoftTransform.h (GU Library, C++)
7  *
8  * COMMENTS:
9  * Applies a transformation based on a supplied distance attribute and a
10  * rolloff.
11  * This is related to the code in GEO_Transform.C, but we don't want to add
12  * yet another function to GEO_Detail, so it has been split off. The code
13  * there is still used for backwards compatibility, but should not be used
14  * in new code.
15  * Note that you are responsible for making empty group parameters become
16  * groups on the whole gdp. An empty group passed to one of these functions
17  * will cause an immediate return (meaning point normals won't be updated
18  * because nothing has been changed).
