## Detailed Description

class `TK_Shell` : public TK_Polyhedron

  Handles the TKE_Shell opcode.

  TK_Shell provides support for writing/reading the TKE_Shell opcode object to/from an HSF file.

  The HOOPS/3dGS scene-graph can contain ‘shell’ primitives which consist of a points array and a connectivity list to define the facets of the shell.

  Subclassed by HTK_Shell

  Public Functions

  `TK_Shell`()
  `~TK_Shell`()
  inline void `set_flist`(int count, int const *list = 0)

    obsolete. Provided for compatibility

  virtual TK_Status `Read`(BStreamFileToolkit &tk)

    Reads data from the toolkit buffer, decodes/decompresses it, and maps it to the opcode handlers data members. User-defined classes which need to write out custom data should utilize one of the available GetData() methods.

    Parameters: | tk – A reference to the BStreamFileToolkit object.
    Returns: | The result of the function call.

  virtual TK_Status `Write`(BStreamFileToolkit &tk)

    Encodes/compresses data and writes data to the toolkit buffer. User-defined classes which need to write out custom data should utilize one of the available PutData() methods, and first write out the opcode associated with the group of binary data followed by the data itself.

    Parameters: | tk – A reference to the BStreamFileToolkit object.
    Returns: | The result of the function call.

  TK_Status `ReadAscii`(BStreamFileToolkit &tk)

    Deprecated.

  TK_Status `WriteAscii`(BStreamFileToolkit &tk)

    Deprecated.

  virtual void `Reset`()

    Resets the current opcode handler. This is called by the toolkit when it is done processing an opcode. This method reinitializes any opcode handler variables and frees up temporary data.
