VisibilityRegion::EllipsoidVisible

Defined in: C4Regions.h

Determines whether an ellipsoid is visible in a region.

Prototype

bool EllipsoidVisible(const Point3D& center, const Vector3D *axis) const;

Parameters

`center`	The world-space center of the ellipsoid.
`axis`	A pointer to an array containing the three semi-axis vectors of the ellipsoid.

Description

The EllipsoidVisible function determines whether the sphere specified by the center and axis parameters is visible inside a region. If the ellipsoid falls completely on the negative side of any single plane bounding the region, then the return value is false. Otherwise, the return value is true.
