## Public Member Functions
| ColorStack ()
| Default constructor.
| ~ColorStack ()
| Destructor.
void | initialize (ACG::GLState *)
| init (takes current GL context/ like glInitNames (); glPushName (0))
bool | initialized () const
| has it been initialized?
bool | setMaximumIndex (size_t _idx)
| sets the maximum index number used in current node
void | setIndex (size_t _idx)
| sets the current color the given index (like glLoadName)
Vec4uc | getIndexColor (size_t _idx)
| gets the color instead of setting it directly
void | pushIndex (size_t _idx)
| creates a new node the stack (like glPushName)
void | popIndex ()
| pops the current node from the stack (like glPopName)
std::vector< size_t > | colorToStack (Vec4uc _rgba) const
| converts the given color to index values on the stack
size_t | freeIndicies () const
| returns maximal available index count
bool | error () const
| Did an error occur during picking.
size_t | currentIndex () const
| returns the current color index
