Detailed Description

BOPAlgo_MakeConnected is the algorithm for making the touching shapes connected or glued, i.e. for making the coinciding geometries be topologically shared among the shapes.

The input shapes should be of the same dimension, otherwise the gluing will not make any sense.

After the shapes are made connected, the border elements of input shapes are associated with the shapes to which they belong. At that, the orientation of the border element in the shape is taken into account. The associations are made for the following types:

For input SOLIDS, the resulting FACES are associated with the input solids;
For input FACES, the resulting EDGES are associated with the input faces;
For input EDGES, the resulting VERTICES are associated with the input edges.

In frames of this algorithm the input shapes are called materials, and the association process is called the material association. The material association allows finding the coinciding elements for the opposite input shapes. These elements will be associated to at least two materials.

After making the shapes connected, it is possible to make the connected shape periodic using the BOPAlgo_MakePeriodic tool. After making the shape periodic, the material associations will be updated to correspond to the actual state of the result shape. Repetition of the periodic shape is also possible here. Material associations are not going to be lost.

The algorithm supports history of shapes modification, thus it is possible to track the modification of the input shapes during the operations. Additionally to standard history methods, the algorithm provides the the method GetOrigins() which allows obtaining the input shapes from which the resulting shape has been created.

The algorithm supports the parallel processing mode, which allows faster completion of the operations.

The algorithm returns the following Error/Warning messages:

BOPAlgo_AlertTooFewArguments - error alert is given on the attempt to run the algorithm without the arguments;
BOPAlgo_AlertMultiDimensionalArguments - error alert is given on the attempt to run the algorithm on multi-dimensional arguments;
BOPAlgo_AlertUnableToGlue - error alert is given if the gluer algorithm is unable to glue the given arguments;
BOPAlgo_AlertUnableToMakePeriodic - warning alert is given if the periodicity maker is unable to make the connected shape periodic with given options;
BOPAlgo_AlertShapeIsNotPeriodic - warning alert is given on the attempt to repeat the shape before making it periodic.

Here is the example of usage of the algorithm:

TopTools_ListOfShape anArguments = ...;  // Shapes to make connected
Standard_Boolean bRunParallel = ...;     // Parallel processing mode
BOPAlgo_MakeConnected aMC;               // Tool for making the shapes connected
aMC.SetArguments(anArguments);           // Set the shapes
aMC.SetRunParallel(bRunParallel);        // Set parallel processing mode
aMC.Perform();                           // Perform the operation
if (aMC.HasErrors())                     // Check for the errors
{
  // errors treatment
  Standard_SStream aSStream;
  aMC.DumpErrors(aSStream);
  return;
}
if (aMC.HasWarnings())                   // Check for the warnings
{
  // warnings treatment
  Standard_SStream aSStream;
  aMC.DumpWarnings(aSStream);
}
const TopoDS_Shape& aGluedShape = aMC.Shape(); // Connected shape
// Checking material associations
TopAbs_ShapeEnum anElemType = ...;       // Type of border element
TopExp_Explorer anExp(anArguments.First(), anElemType);
for (; anExp.More(); anExp.Next())
{
  const TopoDS_Shape& anElement = anExp.Current();
  const TopTools_ListOfShape& aNegativeM = aMC.MaterialsOnNegativeSide(anElement);
  const TopTools_ListOfShape& aPositiveM = aMC.MaterialsOnPositiveSide(anElement);
}
// Making the connected shape periodic
BOPAlgo_MakePeriodic::PeriodicityParams aParams = ...; // Options for periodicity of the connected shape
aMC.MakePeriodic(aParams);
// Shape repetition after making it periodic
// Check if the shape has been made periodic successfully
if (aMC.PeriodicityTool().HasErrors())
{
  // Periodicity maker error treatment
}
// Shape repetition in periodic directions
aMC.RepeatShape(0, 2);
const TopoDS_Shape& aShape = aMC.PeriodicShape(); // Periodic and repeated shape
