# SbOctTreeFuncs(3)

## NAME

SbOctTreeFuncs

## SYNOPSIS

\#include \<Inventor/SbOctTree.h\>

### 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)\

## Detailed Description

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**.

## Member Data Documentation

### SbBool(\* SbOctTreeFuncs::ptinsidefunc) (void \*const item, const SbVec3f &pt)

Should return whether a point is inside item.

### SbBool(\* SbOctTreeFuncs::insideboxfunc) (void \*const item, const SbBox3f &box)

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

### SbBool(\* SbOctTreeFuncs::insidespherefunc) (void \*const item, const SbSphere &sphere)

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

### SbBool(\* SbOctTreeFuncs::insideplanesfunc) (void \*const item, const SbPlane \*const planes, const int numplanes)

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