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.

float* vtkSphericalDirectionEncoder::GetDecodedGradient ( int  value)
virtual

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

Implements vtkDirectionEncoder.

int vtkSphericalDirectionEncoder::GetNumberOfEncodedDirections ( void  )

float* vtkSphericalDirectionEncoder::GetDecodedGradientTable ( void  )
inlinevirtual

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.
