HrcShrinkWrap

The Deformation->HrcShrinkWrap command in the Model module allows you to "shrinkwrap" an entire hierarchy (composed of curves, polygon meshes, patches, or NURBS surfaces) to conform to the surface of a target object that can be a polygon mesh or patch object. This is useful, for example, when shrinkwrapping several curves to a model to create several cross-sections for skinning.

The Deformation->AnimatedShrinkWrap and HrcAnimShrinkWrap commands in the Motion module are the animated versions of this effect.

Procedure

1. Create the following three elements:

• The target object: this is the polygon mesh or patch object toward which the points "shrink." You cannot use a NURBS object as a target object.
• The outer wrapper hierarchy: the points of the outer wrapper model "shrink" until they reach the target object. The outer wrapper model can be a polygon mesh, curve, patch, or NURBS surface object.
• The inner wrapper hierarchy: this model must have the same number of points as the outer wrapper model because points of the outer wrapper move toward the corresponding points of the inner wrapper. This determines the direction of "shrinking" for each point of the outer wrapper.

Note:
Both the inner and outer hierarchies should have the same number of models and points.

2. Choose the Deformation->HrcShrinkWrap command.
   
   The Shrink Wrap dialogue box is displayed.
   
   
3. Set the parameters as desired.
4. Pick the target object, the outer wrapper hierarchy, and then the inner wrapper hierarchy.

Parameters

The parameters are the same as for the Deformation->ShrinkWrap command.
