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.

inline void SetDMinor(double x, double y, double z)

Sets the minor axis of the arc using discrete float values

inline void SetDMinor(double const m[])

Sets the minor axis of the arc using a float triplet

inline double const *GetDMinor() const

Returns the minor axis of the arc as the address of a float triplet

inline void SetLimits(float s, float e)

Sets the parametric limits of the arc using discrete values

inline float const *GetLimits() const
