Detailed Description

The dimeLine class handles a LINE entity.


Constructor & Destructor Documentation

dimeLine::dimeLine  
 

Constructor.


Member Function Documentation

dimeEntity * dimeLine::copy dimeModel *const    model const [virtual]
 

Must be implemented by subclasses to return a copy of the entity. model is the model the new entity should belong to.

Reimplemented from dimeEntity.

int dimeLine::countRecords   const [virtual]
 

Returns the number of records in the record holder. Should be overloaded by subclasses which should count their records, and then call the parent's method. This method is used to precalculate the number of records to be written. Very useful when progress information is needed during write().

Reimplemented from dimeExtrusionEntity.

dimeEntity::GeometryType dimeLine::extractGeometry dimeArray< dimeVec3f > &    verts,
dimeArray< int > &    indices,
dimeVec3f   extrusionDir,
dxfdouble &    thickness
[virtual]
 

A special convenience function, included for your pleasure. Enables the user to ignore the type of entity, and just call this method when extracting geometry. Very useful for 3D viewers that need DXF support. Check out the dxf2vrml directory for an example on how to convert a DXF file to VRML.

Should be overloaded by all subclasses that have geometry, default function returns no geometry. Don't forget to transform vertices by the current transformation matrix if used in a callback from dimeEntity::traverse().

If there are coordinates, but no indices, this means running indices for the entire vertex array.

Different faces and/or line segments are separated by a -1 in the indices array, just as in VRML files.

If thickness != 0.0, the data should, before transformation, be extruded by that length along the extrusion direction. Hence, a point becomes a line, a line becomes a quad, and a polygon becomes an object with a volume.

If thickness == 0.0 and extrusionDir != (0,0,1) all the vertices should be transformed by a matrix that can be created using dimeEntity::generateUCS(). If you are using dimeModel::traverseEntities() to extract the geometry, simply right-multiply the UCS matrix with the matrix found in dimeState to get the correct transformation.

Reimplemented from dimeEntity.

const char * dimeLine::getEntityName   const [virtual]
 

Must be implemented by subclasses to return the entity name; e.g. POLYLINE, 3DFACE, etc.

Reimplemented from dimeEntity.

bool dimeLine::getRecord const int    groupcode,
dimeParam   param,
const int    index = 0
const [virtual]
 

Will return the value of the record with group code groupcode. false is returned if the record could not be found. Subclasses should overload this method if one or several records are stored in the class. If the groupcode queried is not stored internally, the subclass should call its parent's method.

Reimplemented from dimeExtrusionEntity.

bool dimeLine::handleRecord const int    groupcode,
const dimeParam   param,
dimeMemHandler *const    memhandler
[protected, virtual]
 

Handles the callback from dimeEntity::readRecords().

Reimplemented from dimeExtrusionEntity.

int dimeLine::typeId   const [virtual]
 

Must be implemented by all subclasses, and should return an unique id for that class.

Reimplemented from dimeExtrusionEntity.

bool dimeLine::write dimeOutput *const    file [virtual]
 

Writes a Line entity.

Reimplemented from dimeEntity.
