A direction encoder based on the recursive subdivision of an octahedron.
vtkRecursiveSphereDirectionEncoder is a direction encoder which uses the vertices of a recursive subdivision of an octahedron (with the vertices pushed out onto the surface of an enclosing sphere) to encode directions into a two byte value.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.
Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Construct the object.
Initialize the index table which will be used to map the normal into a patch on the recursively subdivided sphere.
Given a normal vector n, return the encoded direction.
Implements vtkDirectionEncoder.
/ Given an encoded value, return a pointer to the normal vector
Implements vtkDirectionEncoder.

Return the number of encoded directions.

Get the decoded gradient table.
There are this->GetNumberOfEncodedDirections() entries in the table, each containing a normal (direction) vector. This is a flat structure - 3 times the number of directions floats in an array.
Implements vtkDirectionEncoder.

Set / Get the recursion depth for the subdivision.
This indicates how many time one triangle on the initial 8-sided sphere model is replaced by four triangles formed by connecting triangle edge midpoints. A recursion level of 0 yields 8 triangles with 6 unique vertices. The normals are the vectors from the sphere center through the vertices. The number of directions will be 11 since the four normals with 0 z values will be duplicated in the table - once with +0 values and the other time with -0 values, and an addition index will be used to represent the (0,0,0) normal. If we instead choose a recursion level of 6 (the maximum that can fit within 2 bytes) the number of directions is 16643, with 16386 unique directions and a zero normal.
