Polygon occlusion primitive for use with the [Occluder] node.

|
[OccluderShape]s are resources used by [Occluder] nodes, allowing geometric occlusion culling.
|
|
The polygon must be a convex polygon. The polygon points can be created and deleted either in the Editor inspector or by calling [code]set_polygon_points[/code]. The points of the edges can be set by dragging the handles in the Editor viewport.
|
|
Additionally each polygon occluder can optionally support a single hole. If you add at least three points in the Editor inspector to the hole, you can drag the edge points of the hole in the Editor viewport.
|
|
In general, the lower the number of edges in polygons and holes, the faster the system will operate at runtime, so in most cases you will want to use 4 points for each.
