|
Copies the coordinates from entity. |
|
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 dimeEntity. Reimplemented in dime3DFace, dimeSolid, and dimeTrace. |
|
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. |
|
Default method returns (0,0,1). Should be overloaded if this is not correct for all cases. |
|
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 dimeEntity. Reimplemented in dime3DFace, dimeSolid, and dimeTrace. |
|
Default method return 0.0. Should be overloaded if this is not correct for all cases. |
|
Returns vertex nr idx. |
|
Returns all four vertices. |
|
Must be overloaded by entities that directly supports a record type. During dimeRecordHolder::read(), dimeRecordHolder::setRecord and dimeRecordHolder::setRecords, this function is called for every record found, and it is up to the subclass if the record should be stored internally, or if a generic record should be created and stored in this superclass. A subclass should return when it will handle the record, false otherwise. Default function does nothing, and returns false. For entities, records with group codes 8 (layer name) and 62 (color number) are automatically handled by the dimeEntity class.
Reimplemented from dimeEntity. Reimplemented in dime3DFace, dimeSolid, and dimeTrace. |
|
Returns true if the object is of type typeid or is inherited from it. Function in base class checks whether thetypeid equals the virtual dimeBase::typeId() value or equals dimeBaseType. Must be implemented by all subclasses that are superclasses of other classes, and should check if thetypeid equals its typeId, and then call its parent's isOfType function. Leaf-classes do not have to implement this method. Reimplemented from dimeEntity. |
|
Sets vertices to create a quad. |
|
Sets vertices to create a triangle. |
|
Default function returns false. If true is returned, the last two vertices will be swapped before returning geometry in extractGeometry(). |
|
Must be implemented by all subclasses, and should return an unique id for that class. Implements dimeBase. Reimplemented in dime3DFace, dimeSolid, and dimeTrace. |
|
Will write the coordinate data to out. Should be called by subclasses at some time during write. |
