Detailed Description

Provides HOOPS/3dGS-specific handling of the TKE_Camera opcode.

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.

constructor

Member Function Documentation

◆ Clone()

TK_Status HTK_Camera::Clone ( BStreamFileToolkit tk,
BBaseOpcodeHandler **  handler 
) const
virtual

Copies the opcode handler

Parameters
tkA reference to the BStreamFileToolkit object.
handlerA pointer to the opcode handler object. Passed by reference.
Returns
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

◆ Execute()

TK_Status HTK_Camera::Execute ( BStreamFileToolkit tk)
virtual

Processes the binary data that has been read for the current object, which involves passing the data to application-specific data structures.

Parameters
tkA reference to the BStreamFileToolkit object.
Returns
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

◆ Interpret() [1/2]

TK_Status HTK_Camera::Interpret ( BStreamFileToolkit tk,
ID_Key  key,
int  variant = 0 
)
virtual

Extracts graphics data (typically from the application's scene-graph) and maps it to the opcode handler's data members in preparation for writing out an object to the file.

Parameters
tkA reference to the BStreamFileToolkit object.
keyAn identifier to the object (for example, the HOOPS key of a geometry item)
variantoptional specification of an alternate form, such as a Level-of-Detail representation
Returns
The result of the function call.

Reimplemented from BBaseOpcodeHandler.

◆ Interpret() [2/2]

TK_Status HTK_Camera::Interpret ( BStreamFileToolkit tk,
ID_Key  key,
char const *  special 
)
inlinevirtual

Extracts graphics data (typically from the application's scene-graph) and maps it to the opcode handler's data members in preparation for writing out an object to the file.

Parameters
tkA reference to the BStreamFileToolkit object.
keyAn identifier to the object (for example, the HOOPS key of a geometry item)
specialA string value of particular data
Returns
The result of the function call.

Reimplemented from BBaseOpcodeHandler.
