Detailed Description

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

constructor


Member Function Documentation

TK_Status TK_Area_Light::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.

int TK_Area_Light::GetCount (  )  const [inline]

Returns the number of points in the buffer

double* TK_Area_Light::GetDPoints (  )  [inline]

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

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

Returns the address of the point buffer

int TK_Area_Light::GetOptions (  )  const [inline]

Returns the options for the light

float* 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.

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

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::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_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.

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

Implements BBaseOpcodeHandler.
