Breakup

The Polygon->Breakup command in the Model module allows you to modify a polygon mesh object so that no vertex is referenced by more than one polygon. For example, a cube with eight vertices and six polygons has 24 vertices and six polygons after the Breakup effect is applied. This allows you to manipulate individual polygons to "break up" the polygon mesh object. Normals at vertices are preserved so the rendered image is the same after the Breakup effect is applied.

The Breakup effect is typically combined with other custom effects, such as Effects->Explode and Draw->PolySkin, to create more complex effects.

Procedure

1. Create a polygon mesh.
2. Choose the Polygon->Breakup command.
   
   The Breakup dialogue box is displayed.
   
   
3. Select the Tagged Points Only option, if you want the polygon mesh to break up at only the tagged points.
4. Select the polygon mesh object. A new polygon mesh is created, replacing the original polygon mesh at exactly the same location.
