Public Attributes

SbBool(* ptinsidefunc )(void *const item, const SbVec3f &pt)

SbBool(* insideboxfunc )(void *const item, const SbBox3f &box)

SbBool(* insidespherefunc )(void *const item, const SbSphere &sphere)

SbBool(* insideplanesfunc )(void *const item, const SbPlane *const planes, const int numplanes)

The SbOctTreeFuncs struct is used to specify callback functions for working with items in an SbOctTree.

The only function pointer that must be set up is insideboxfunc. The other functions must be set if you intend to use the corresponding find methods in SbOctTree.

SbOctTreeFuncs::ptinsidefunc

Should return whether a point is inside item.

SbOctTreeFuncs::insideboxfunc

Should return whether item is either fully or partly inside a box.

SbOctTreeFuncs::insidespherefunc

Should return whether item is either fully or partly inside a sphere.

SbOctTreeFuncs::insideplanesfunc

Should return whether item is either fully or partly inside a set of planes.
