[vtkusers] OBBTree animation

[Francois Bertel]

Hello,

1. Yes, it is possible to include images within doxygen:

http://www.vtk.org/doc/nightly/html/classvtkSobelGradientMagnitudePass.html
http://www.vtk.org/doc/nightly/html/classvtkGlobeSource.html

For example, vtkSobelGradientMagnitudePass.h has the following lines
in the description of the class:

// \image html vtkSobelGradientMagnitudePassFigure.png
// \image latex vtkSobelGradientMagnitudePassFigure.eps


2. Read the hyperoctree description again:

"An hyperoctree is a dataset where each node has either exactly 2^n
children **** or no child at all  **** if the node is a leaf."

Actually, it is missing that "n" is the dimension of the hyperoctree
(n=1,2 or 3) so it is a binary tree (n=1)  a quadtree (n=2) or an
octree (n=3)

Also, in the doc: "Warning:  It is not a spatial search object! If you
looking for this kind of octree see vtkCellLocator instead."
