Detailed Description
-
class TK_Camera : public BBaseOpcodeHandler
Handles the TKE_Camera opcode.
TK_Camera provides support for writing/reading the TKE_Camera opcode object to/from an HSF file.
The HOOPS/3dGS scene-graph supports a camera, which is a segment attribute defining a specific view of world space.
Public Functions
-
inline TK_Camera(unsigned char opcode = TKE_Camera)
constructor
-
~TK_Camera()
-
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.
