HTK_Bounding
Functions
Detailed Description
-
class HTK_Bounding : public TK_Bounding
Provides HOOPS/3dGS-specific handling of the TKE_Bounding and TKE_Bounding_Info opcodes.
This class complements the read/write functionality implemented in the base class by overloading the Interpret and Execute methods to provide HOOPS/3dGS-specific opcode handling.
Writing: The HOOPS/3dGS database is queried in the Interpret method, and this data is then written to the HSF file by the Write method Reading: The data is read from the HSF file by the Read method, and is mapped to the HOOPS/3dGS scene-graph within the Execute method.
Export/import of additional user-data (which is associated with this HSF object) would typically be done by overloading the Write and Read methods.
Two different opcodes are used as follows: The TKE_Bounding opcode will export a bounding volume that was explicitly set on a HOOPS segment (if any). The TKE_Bounding_Info will cause an explicit computation of the HOOPS/3dGS bounding information and export it.
Public Functions
-
inline HTK_Bounding(unsigned char opcode)
default constructor
-
inline HTK_Bounding(unsigned char opcode, float *min, float *max)
constructor that accepts min and max values
-
inline HTK_Bounding(unsigned char opcode, float *center, float radius)
constructor that accepts center and radius values
-
virtual TK_Status Execute(BStreamFileToolkit &tk)
Processes the binary data that has been read for the current object, which involves passing the data to application-specific data structures.
- Parameters
tk – A reference to the BStreamFileToolkit object.
- Returns
The result of the function call.
-
TK_Status Interpret(BStreamFileToolkit &tk, ID_Key key, int variant = 0)
-
inline TK_Status Interpret(BStreamFileToolkit &tk, ID_Key key, char const *special)
-
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.
-
inline HTK_Bounding(unsigned char opcode)
