Detailed Description

encode a direction into a one or two byte value

Given a direction, encode it into an integer value. This value should be less than 65536, which is the maximum number of encoded directions supported by this superclass. A direction encoded is used to encode normals in a volume for use during volume rendering, and the amount of space that is allocated per normal is 2 bytes. This is an abstract superclass - see the subclasses for specific implementation details.

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

Given a normal vector n, return the encoded direction

Implemented in vtkRecursiveSphereDirectionEncoder, and vtkSphericalDirectionEncoder.

virtual float* vtkDirectionEncoder::GetDecodedGradient ( int  value)
pure virtual

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

Implemented in vtkRecursiveSphereDirectionEncoder, and vtkSphericalDirectionEncoder.

virtual int vtkDirectionEncoder::GetNumberOfEncodedDirections ( void  )
pure virtual

Return the number of encoded directions

Implemented in vtkRecursiveSphereDirectionEncoder, and vtkSphericalDirectionEncoder.

virtual float* vtkDirectionEncoder::GetDecodedGradientTable ( void  )
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.

Implemented in vtkRecursiveSphereDirectionEncoder, and vtkSphericalDirectionEncoder.
