Determines if a ray intersects the volume of a sphere's bounding box.
object.SphereBoundProbe( _ Center As D3DVECTOR, _ Radius As Single, _ RayPosition As D3DVECTOR, _ Raydirection As D3DVECTOR) As Boolean
Returns TRUE if the ray intersects the volume of the sphere's bounding box. Otherwise, returns FALSE.
If the method fails, an error is raised and Err.Number can be set to D3DXERR_INVALIDMESH.
For information on trapping errors, see the Microsoft® Visual Basic® Error Handling topic.
D3DXSphereBoundProbe determines if the ray intersects the volume of the sphere's bounding box, not just the surface of the sphere.
