Detailed Description

class TK_Polypoint : public BBaseOpcodeHandler

Handles the TKE_Polyline and TKE_Polygon opcodes.

TK_Polypoint provides support for writing/reading the TKE_Polyline and TKE_Polygon opcode objects to/from an HSF file.

The HOOPS/3dGS scene-graph supports ‘polyline’ and ‘polygon’ primitives which are both defined by a point count and points array.

See also TK_PolyPolypoint.

Public Functions

inline TK_Polypoint(unsigned char opcode): constructor

~TK_Polypoint()

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.

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.

void SetPoints(int count, float const points[] = 0): Sets the point array. Allocates a buffer which will hold ‘count’ float triplets, and if specified, copies the ‘points’ into the buffer

inline float const *GetPoints() const: Returns the address of the point buffer

inline float *GetPoints(): Returns the address of the point buffer, which may be modified directly

void SetDPoints(int count, double const points[] = 0): Sets the point array. Allocates a buffer which will hold ‘count’ double triplets, and if specified, copies the ‘points’ into the buffer

inline double const *GetDPoints() const: Returns the address of the point buffer

inline double *GetDPoints(): Returns the address of the point buffer, which may be modified directly

inline int GetCount() const: Returns the number of points in the buffer
