Property Value

A primitive's BoundingSphere 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 BoundingSphere.

A user may set this property to false in cases when they can determine a BoundingSphere 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.
