Detailed Description

Handles the TKE_Polyline and TKE_Polygon opcodes.

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.


Constructor & Destructor Documentation

TK_Polypoint::TK_Polypoint ( unsigned char  opcode  )  [inline]

constructor


Member Function Documentation

TK_Status TK_Polypoint::Clone ( BStreamFileToolkit tk,
BBaseOpcodeHandler **  handler 
) const [virtual]

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.

Reimplemented from BBaseOpcodeHandler.

Reimplemented in HTK_Polypoint.

int TK_Polypoint::GetCount (  )  const [inline]

Returns the number of points in the buffer

double* TK_Polypoint::GetDPoints (  )  [inline]

Returns the address of the point buffer, which may be modified directly

double const* TK_Polypoint::GetDPoints (  )  const [inline]

Returns the address of the point buffer

float* 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.

Parameters:
tk A reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

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::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

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.

Parameters:
tk A reference to the BStreamFileToolkit object.
Returns:
The result of the function call.

Implements BBaseOpcodeHandler.
