Construct the object. Initialize the index table which will be used to map the normal into a patch on the recursively subdivided sphere.

int vtkSphericalDirectionEncoder::GetEncodedDirection ( float n[3])

virtual

Given a normal vector n, return the encoded direction

Implements vtkDirectionEncoder.

virtual

/ Given an encoded value, return a pointer to the normal vector

Implements vtkDirectionEncoder.

int vtkSphericalDirectionEncoder::GetNumberOfEncodedDirections ( void )

inlinevirtual

Return the number of encoded directions

Implements vtkDirectionEncoder.

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.
