Detailed Description

class TK_Matrix : public BBaseOpcodeHandler

Handles the TKE_Modelling_Matrix and TKE_Texture_Matrix opcodes.

TK_Matrix provides support for writing/reading the TKE_Modelling_Matrix and TKE_Texture_Matrix opcode objects to/from an HSF file.

The HOOPS/3dGS scene-graph supports modelling and texture matrices.

Public Functions

inline TK_Matrix(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 SetMatrix(float const m[]): Sets the matrix to the specified values

inline void SetDMatrix(double const m[]): Sets the matrix to the specified values

inline float const *GetMatrix() const: Returns the matrix as the address of the array of floats

inline float *GetMatrix(): Returns the matrix as the address of the array of floats, which may be modified directly

inline double const *GetDMatrix() const: Returns the matrix as the address of the array of doubles

inline double *GetDMatrix(): Returns the matrix as the address of the array of doubles, which may be modified directly
