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.

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.
