Handles the TKE_Window opcode.
TK_Window provides support for writing/reading the TKE_Window opcode object to/from an HSF file.
The HOOPS/3dGS scene-graph supports a window attributes, which defines a local viewport with it's own unique camera.
TK_Window::TK_Window | ( | ) | [inline] |
constructor
TK_Status TK_Window::Clone | ( | BStreamFileToolkit & | tk, |
BBaseOpcodeHandler ** | handler | ||
) | const [virtual] |
Copies the opcode handler
tk | A reference to the BStreamFileToolkit object. |
handler | A pointer to the opcode handler object. Passed by reference. |
Reimplemented from BBaseOpcodeHandler.
float const* TK_Window::GetWindow | ( | ) | const [inline] |
Returns the subwindow region as the address of an array of four floats
TK_Status TK_Window::Read | ( | BStreamFileToolkit & | tk | ) | [virtual] |
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.
tk | A reference to the BStreamFileToolkit object. |
Implements BBaseOpcodeHandler.
void TK_Window::SetWindow | ( | float | l, |
float | r, | ||
float | b, | ||
float | t | ||
) | [inline] |
Sets the subwindow region using discrete float values
void TK_Window::SetWindow | ( | float const | w[] | ) | [inline] |
Sets the subwindow region using an array of four floats
References SetWindow().
Referenced by SetWindow().
TK_Status TK_Window::Write | ( | BStreamFileToolkit & | tk | ) | [virtual] |
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.
tk | A reference to the BStreamFileToolkit object. |
Implements BBaseOpcodeHandler.
