Detailed Description
-
class TK_Area_Light : public BBaseOpcodeHandler
Handles the TKE_Area_Light opcode.
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
Public Functions
-
inline TK_Area_Light()
constructor
-
~TK_Area_Light()
-
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.
-
virtual void Reset()
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.
-
inline void SetPoints(int count, float const points[] = 0)
Sets the point array. Allocates a buffer which will hold ‘count’ float triplets, and if specified, copies the ‘points’ into the buffer
-
inline float const *GetPoints() const
Returns the address of the point buffer
-
inline float *GetPoints()
Returns the address of the point buffer, which may be modified directly
-
void SetDPoints(int count, double const points[] = 0)
Sets the point array. Allocates a buffer which will hold ‘count’ double triplets, and if specified, copies the ‘points’ into the buffer
-
inline double const *GetDPoints() const
Returns the address of the point buffer
-
inline double *GetDPoints()
Returns the address of the point buffer, which may be modified directly
-
inline int GetCount() const
Returns the number of points in the buffer
-
inline void SetOptions(int o)
Sets the options for the light
-
inline int GetOptions() const
Returns the options for the light
-
inline TK_Area_Light()
