20 Managing Bounding Spheres
Q3BoundingSphere_UnionPoint3D
function to find the union of a bounding sphere and a three-dimensional point.
TQ3BoundingSphere *Q3BoundingSphere_UnionPoint3D ( const TQ3BoundingSphere *bSphere, const TQ3Point3D *pt3D, TQ3BoundingSphere *result);bSphere
A pointer to a bounding sphere.pt3D
A three-dimensional point.result
On exit, a pointer to the union of the specified bounding sphere and the specified point.
Q3BoundingSphere_UnionPoint3D
function returns, as its function result and in the result
parameter, a pointer to the bounding sphere that is the union of the bounding sphere specified by the bSphere
parameter and the three-dimensional point specified by the pt3D
parameter. The result
parameter can point to the memory pointed to by bSphere
, thereby performing the union operation in place.
