Detailed Description

Handles the TKE_Visibility opcode.

TK_Visibility provides support for writing/reading the TKE_Visibility opcode object to/from an HSF file.

The HOOPS/3dGS scene-graph supports an attribute called Visibility which affects the display of objects.

constructor


Member Function Documentation

TK_Status TK_Visibility::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_Visibility.

int TK_Visibility::GetGeometry (  )  const [inline]

Returns the mask indicating which geometries have a visibility setting. Geometry types are specified by TKO_Geometry_Bits.

int TK_Visibility::GetValue (  )  const [inline]

Returns the mask indicating which geometries have visibility set on. Geometry types are specified by TKO_Geometry_Bits.

TK_Status TK_Visibility::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_Visibility::SetGeometry ( int  m  )  [inline]

Sets the mask indicating which geometries have a visibility setting. Geometry types are specified by TKO_Geometry_Bits.

References TKO_Geo_All_Visibles, TKO_Geo_Extended, TKO_Geo_Extended2, TKO_Geo_Extended2_Mask, and TKO_Geo_Extended_Mask.

void TK_Visibility::SetValue ( int  m  )  [inline]

Sets the mask indicating which geometries have visibility set on. Geometry types are specified by TKO_Geometry_Bits.

TK_Status TK_Visibility::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.
