Detailed Description

Octree implementation.

Constructor & Destructor Documentation

iOctree()

igor::iOctree::iOctree	(	const iAACubed &	box,
		float64	halfMinResolution = 1.0,
		uint64	objectCountMaxThreashold = 8,
		uint64	objectCountMinThreashold = 2
	)

creates the octree including the root node

Parameters

box	volume of the whole octree
halfMinResolution	half of the minimum size a octree nodes volume has
objectCountMaxThreashold	maximum amount of objects before splitting the parenting octree node
objectCountMinThreashold	minimum amount of objects in the child nodes of a node before merging them together

Member Function Documentation

addFilter() [1/3]

void igor::iOctree::addFilter

(

const iaSphered &

sphere

)

adds sphere to filter set

Parameters

sphere

the sphere to filter with

addFilter() [2/3]

void igor::iOctree::addFilter

(

const iFrustumd &

frustum

)

adds frustum to filter set

Parameters

frustum

the frustum

addFilter() [3/3]

void igor::iOctree::addFilter

(

const iPlaned &

plane

)

adds plane to filter set

Parameters

plane

the plane to filter with

clearFilter()

void igor::iOctree::clearFilter

(

)

clears filter set

draw()

void igor::iOctree::draw

(

)

draws the octrees structure

only use for debugging!

filter() [1/2]

void igor::iOctree::filter

(

)

filters the octree using the current filter set

use getResult to get the result

filter() [2/2]

void igor::iOctree::filter

(

const iFrustumd &

frustum

)

filters the octree with given frustum

use getResult to get the result

Parameters

frustum

the given frustum

getResult()

const std::vector< void * > & igor::iOctree::getResult

(

)

const

returns the result of filtering

Returns

the filtered user data

insert()

void igor::iOctree::insert	(	void *	userData,
		const iaSphered &	sphere
	)

insert user data to octree

Parameters

userData

pointer to user data

remove()

void igor::iOctree::remove

(

void *

userData

)

remove user data from octree

Parameters

userData

pointer to user data

update()

void igor::iOctree::update	(	void *	userData,
		const iaSphered &	sphere
	)

update user data in octree

this is called usually if the user data changed it's position

Parameters

userData

pointer to user data
