Bounding Spheres

A bounding sphere is a sphere that completely encloses an object. A bounding sphere is defined by the TQ3BoundingSphere data type.

typedef struct TQ3BoundingSphere {
    TQ3Point3D                          origin;
    float                               radius;
    TQ3Boolean                          isEmpty;
} TQ3BoundingSphere;


origin

The origin of the bounding sphere.

radius

The radius of the bounding sphere; all points making up the bounding sphere are this far away from the origin of the sphere.

isEmpty

A Boolean value that specifies whether the bounding sphere is empty ( kQ3True ) or not ( kQ3False ). If this field contains the value kQ3True , the other field of this structure are invalid.
