Member Function Documentation

virtual float* mitkDirectionEncoder::GetDecodedGradient (  int  value  )  [pure virtual]

Given an encoded value, return a pointer to the normal vector Parameters: value  Represent the encoded value Implemented in mitkRecursiveSphereDirectionEncoder.

virtual float* mitkDirectionEncoder::GetDecodedGradientTable (   )  [pure 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. Returns: Return the decoded gradient table Implemented in mitkRecursiveSphereDirectionEncoder.

virtual int mitkDirectionEncoder::GetEncodedDirection (  float  n[3]  )  [pure virtual]

Given a normal vector n, return the encoded direction Parameters: n  Represent the normal vector Implemented in mitkRecursiveSphereDirectionEncoder.

virtual int mitkDirectionEncoder::GetNumberOfEncodedDirections (   )  [pure virtual]

Get the number of encoded directions Returns: Return the number of encoded directions Implemented in mitkRecursiveSphereDirectionEncoder.
