Detailed Description

class TK_Ellipse : public BBaseOpcodeHandler 

Handles the TKE_Ellipse and TKE_Elliptical_Arc opcodes.

TK_Ellipse provides support for writing/reading the TKE_Ellipse and TKE_Elliptical_Arc opcode objects to/from an HSF file.

The HOOPS/3dGS scene-graph can contain ‘ellipse’ and ‘elliptical arc’ primitives which are defined by center, major and minor points, as well as two parameterization values in the case of an elliptical arc.

Subclassed by HTK_Ellipse

Public Functions

inline TK_Ellipse(unsigned char opcode): constructor

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.

virtual TK_Status Clone(BStreamFileToolkit &tk, BBaseOpcodeHandler **handler) const

Copies the opcode handler

Parameters:	tk – A reference to the BStreamFileToolkit object. handler – A pointer to the opcode handler object. Passed by reference.
Returns:	The result of the function call.

TK_Status ReadAscii(BStreamFileToolkit &tk): Deprecated.

TK_Status WriteAscii(BStreamFileToolkit &tk): Deprecated.
