Q3BoundingSphere_Copy

You can use the Q3BoundingSphere_Copy function to make a copy of a bounding sphere.

TQ3BoundingSphere *Q3BoundingSphere_Copy (
const TQ3BoundingSphere *src, 
TQ3BoundingSphere *dest);

src

A pointer to the bounding sphere to be copied.

dest

On entry, a pointer to a buffer large enough to hold a bounding sphere. On exit, a pointer to a copy of the bounding sphere specified by the src parameter.

DESCRIPTION

The Q3BoundingSphere_Copy function returns, as its function result and in the dest parameter, a copy of the bounding sphere specified by the src parameter. Q3BoundingSphere_Copy does not allocate any memory for the destination bounding sphere; the dest parameter must point to space allocated in the heap or on the stack before you call Q3BoundingSphere_Copy.
