virtual const char* vtkSphericalDirectionEncoder::GetClassName (   )  [virtual]

Get the name of this class Reimplemented from vtkDirectionEncoder.

static int vtkSphericalDirectionEncoder::IsTypeOf (  const char *  type  )  [static]

Get the name of this class Reimplemented from vtkDirectionEncoder.

virtual int vtkSphericalDirectionEncoder::IsA (  const char *  type  )  [virtual]

Get the name of this class Reimplemented from vtkDirectionEncoder.

static vtkSphericalDirectionEncoder* vtkSphericalDirectionEncoder::SafeDownCast (  vtkObject *  o  )  [static]

Get the name of this class Reimplemented from vtkDirectionEncoder.

void vtkSphericalDirectionEncoder::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Get the name of this class Reimplemented from vtkDirectionEncoder.

static vtkSphericalDirectionEncoder* vtkSphericalDirectionEncoder::New (   )  [static]

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

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   )  [inline, virtual]

Return the number of encoded directions Implements vtkDirectionEncoder. Definition at line 48 of file vtkSphericalDirectionEncoder.h.

float* vtkSphericalDirectionEncoder::GetDecodedGradientTable (  void   )  [inline, virtual]

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. Definition at line 55 of file vtkSphericalDirectionEncoder.h.

static void vtkSphericalDirectionEncoder::InitializeDecodedGradientTable (   )  [static, protected]

Initialize the table at startup
