Wrap Prep SOP

Overview

This sop is one of 3 sops that use one surface to deform another based on the weighted proximity of the points in the driver surface to the deformed one. This sop performs the preparation phase on the driver surface by turning it into a collect of points with axis attributes.  The surface will appear to dissappear but all that has happened is that it has been turned into a point cloud with a point at the center of each of the input polygons.

Usage

The surface to be prepared must be polygons, that's about it I think.  Once this step has happened it can be wired into a Wrap capture and Wrap deform sop.  If you don't use this sop first then the other two won't work.

Parameters

Add disc radius One of the options of the Wrap capture sop is to use visibility weighting if you choose that option then this disc radius attrubute needs calculating, so turn this toggle on.
Keep prim col Turning this on means you have the option to see in colour which polys are used in the capture step.
