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.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkObject.
Reimplemented in vtkSphericalDirectionEncoder, and vtkRecursiveSphereDirectionEncoder.

◆ PrintSelf()
|
virtual |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkObject.
Reimplemented in vtkSphericalDirectionEncoder, and vtkRecursiveSphereDirectionEncoder.
◆ GetEncodedDirection()
Given a normal vector n, return the encoded direction
Implemented in vtkSphericalDirectionEncoder, and vtkRecursiveSphereDirectionEncoder.
◆ GetDecodedGradient()
/ Given an encoded value, return a pointer to the normal vector
Implemented in vtkSphericalDirectionEncoder, and vtkRecursiveSphereDirectionEncoder.
◆ GetNumberOfEncodedDirections()
|
pure virtual |
Return the number of encoded directions
Implemented in vtkSphericalDirectionEncoder, and vtkRecursiveSphereDirectionEncoder.
◆ 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.
Implemented in vtkSphericalDirectionEncoder, and vtkRecursiveSphereDirectionEncoder.
