- /// A simple utility to determine the unique set of used indices
- ///
- /// The utility needs to know the index of the maximum vertex index that is going to be processed
- /// doing so allows it to use very fast array lookups to determine if an index has already been added.
- ///
- /// Before any indices can be added the 'initialize' method must be called with the number of vertex indices
- /// (ie. 1 more than the maximum index value). Now indices can be added by calling 'addIndex' - it will return
- /// the index given to that index.
- ///
- /// The m_uniqueIndices member will hold the original indices of the indices added. The position in uniqueIndices
- /// determines what value was assigned to that index.
- ///
- /// The member m_indexMap - holds -1 for any source index which wasn't added, or the index of the output index for the
- /// the source index otherwise.
