TK_Area_Light provides support for writing/reading the TKE_Area_Light opcode object to/from an HSF file.
The HOOPS/3dGS scene-graph supports 'area-lights' which define a polygon that emits light

constructor
TK_Status TK_Area_Light::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.
int TK_Area_Light::GetCount | ( | ) | const [inline] |
Returns the number of points in the buffer
int TK_Area_Light::GetOptions | ( | ) | const [inline] |
Returns the options for the light
float alter* TK_Area_Light::GetPoints | ( | ) | [inline] |
Returns the address of the point buffer, which may be modified directly
float const* TK_Area_Light::GetPoints | ( | ) | const [inline] |
Returns the address of the point buffer
TK_Status TK_Area_Light::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_Area_Light::Reset | ( | ) | [virtual] |
Resets the current opcode handler. This is called by the toolkit when it is done processing an opcode. This method reinitializes any opcode handler variables and frees up temporary data.
Reimplemented from BBaseOpcodeHandler.
void TK_Area_Light::SetOptions | ( | int | o | ) | [inline] |
Sets the options for the light
void TK_Area_Light::SetPoints | ( | int | count, | |
float const * | points = 0 | |||
) | [inline] |
Sets the point array. Allocates a buffer which will hold 'count' float triplets, and if specified, copies the 'points' into the buffer
TK_Status TK_Area_Light::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.
