Detailed Description

class TK_Spot_Light : public BBaseOpcodeHandler

Handles the TKE_Spot_Light opcode.

TK_Spot_Light provides support for writing/reading the TKE_Spot_Light opcode object to/from an HSF file.

The HOOPS/3dGS scene-graph supports ‘spot-lights’ which define a light cone

Subclassed by HTK_Spot_Light

Public Functions

inline TK_Spot_Light()

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.
