VisibilityRegion::CylinderVisible

Defined in: C4Regions.h

Determines whether a cylinder is visible in a region.

Prototype

bool CylinderVisible(const Point3D& p1, const Point3D& p2, float radius) const;

Parameters

`p1`	The world-space center of one end of the cylinder.
`p2`	The world-space center of the other end of the cylinder.
`radius`	The radius of the cylinder.

Description

The CylinderVisible function determines whether the cylinder specified by the p1, p2, and radius parameters is visible inside a region. The cylinder's axis is clipped as it is tested against each plane bounding the region. If at any point the clipped cylinder falls completely on the negative side of a single plane then the return value is false. Otherwise, the return value is true.
