Detailed Description

1D texture holding empty-space skipping information.

---

Constructor & Destructor Documentation

~Octree

(

)

[virtual]

Deletes the texture data.

Todo:

Should recursively delete root.

---

Member Function Documentation

void associate

(

)

[virtual]

Finds the 3D texture the octree should generate itself from.

Exceptions:

NodeException

if the octree could not find the 3D texture.

Reimplemented from Texture.

void finalize

(

)

[virtual]

Builds an octree and then calls load().

Reimplemented from Node.

GLint getRawFootprint

(

)

const [inline, virtual]

How much memory the texture uses if uncompressed.

Implements Texture.

void load

(

)

[protected, virtual]

Loads the octree data into the texture.

void store	(	OctreeNode *	node,
		int	index,
		int	depth
	)			[virtual]

Recursively stores an octree node and its children into the texture data.

Parameters:

[in]	node	Pointer to the octree node.
[in]	index	Where to store the node in the array.
[in]	depth	Current number of levels down from the root

string toString

(

)

const [virtual]

Forms a string using the Texture's attributes.

Reimplemented from Texture.
