TK_Polypoint provides support for writing/reading the TKE_Polyline and TKE_Polygon opcode objects to/from an HSF file.
The HOOPS/3dGS scene-graph supports 'polyline' and 'polygon' primitives which are both defined by a point count and points array.
See also TK_PolyPolypoint.
TK_Polypoint::TK_Polypoint | ( | unsigned char | opcode | ) | [inline] |
constructor
TK_Status TK_Polypoint::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.
Reimplemented in HTK_Polypoint.
int TK_Polypoint::GetCount | ( | ) | const [inline] |
Returns the number of points in the buffer
float alter* TK_Polypoint::GetPoints | ( | ) | [inline] |
Returns the address of the point buffer, which may be modified directly
float const* TK_Polypoint::GetPoints | ( | ) | const [inline] |
Returns the address of the point buffer
TK_Status TK_Polypoint::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_Polypoint::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_Polypoint::set_points | ( | int | count, | |
float const * | points = 0 | |||
) | [inline, protected] |
for source compatibility in older versions
void TK_Polypoint::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
TK_Status TK_Polypoint::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.
int TK_Polypoint::m_allocated [protected] |
internal use; Number of points the allocated array can contain
int TK_Polypoint::m_count [protected] |
internal use; number of 3D points that define this polypoint object
float* TK_Polypoint::m_points [protected] |
internal use; Array of floats which denote the point coordinates.
