Remarks
A primitive's Bounding
Sphere is used for visibility tests to improve rendering
performance. When AutomaticallyComputeBoundingSphere
is true, the sphere is automatically computed when a
primitive's geometry or position is modified due to a
Set or SetPartial call. Otherwise, it is
the caller's responsibility to set the primitive's Bounding
Sphere.
A user may set this property to false in cases when
they can determine a Bounding
Sphere that encompasses everywhere a dynamic primitive may move
to. This can improve performance by eliminating the overhead
associated with re-computing the bounding sphere and updating the
primitive manager's spatial data structures.
