Detailed Description

This is an implementation of field access by an octree.

virtual bool allocate(visAdaptiveGrid *source, visAttrComb* attrComb, int maxlevel)

Allocate Octree with another Field. AttrComb is used as a criteria for merging nodes and the build tree won't have a height greater than maxlevel (root node is defined to have level = 0!).

virtual bool allocate(istream &in)

Allocate Octree with given stream. The stream in general is a file stream and the format is described in http://??? .
