Defined in: C4Regions.h

Determines whether a polygon is occluded in a region.

Prototype

bool PolygonOccluded(int32 vertexCount, const Point3D *vertex) const;

Parameters

`vertexCount`	The number of vertices in the polygon.
`vertex`	A pointer to an array containing the polygon's world-space vertex positions.

Description

The PolygonOccluded function determines whether the polygon specified by the vertexCount and vertex parameters is occluded by a region. If all the vertex positions fall on the positive side of all the planes bounding the region, then the return value is true. Otherwise, the return value is false.
