# Regions: Kinds

2 of 10

There are three kinds of regions that can be created in LightZone. Each kind is useful in certain situations.

| The Polygon region button creates a region having straight lines connecting the control points.
| The Bézier region button creates a region having curved lines connecting the control points. Moving a control point may affect the overall shape of the region.
| The Spline region button creates a region much like a Bézier, yet the region boundary is defined inside the control points. Moving a control point only locally affects the shape of the region.
