Detailed Description

The algorithm is to build solids from set of shapes. It uses the BOPAlgo_Builder algorithm to intersect the given shapes and build the images of faces (if needed) and BOPAlgo_BuilderSolid algorithm to build the solids.

Steps of the algorithm:

  1. Collect all faces: intersect the shapes if necessary and collect the images of faces, otherwise just collect the faces to the <myFaces> list; All faces on this step added twice, with orientation FORWARD and REVERSED;
  2. Create bounding box covering all the faces from <myFaces> and create solid box from corner points of that bounding box (myBBox, mySBox). Add faces from that box to <myFaces>;
  3. Build solids from <myFaces> using BOPAlgo_BuilderSolid algorithm;
  4. Treat the result: Eliminate solid containig faces from <mySBox>;
  5. Fill internal shapes: add internal vertices and edges into created solids;
  6. Prepare the history.

Fields: <myIntersect> - boolean flag. It defines whether intersect shapes from <myArguments> (if set to TRUE) or not (FALSE). The default value is TRUE. By setting it to FALSE the user should guarantee that shapes in <myArguments> do not interfere with each other, otherwise the result is unpredictable.

<myBBox> - bounding box, covering all faces from <myFaces>.

<mySBox> - Solid box created from the corner points of <myBBox>.

<myFaces> - the list is to keep the "final" faces, that will be given to the BOPAlgo_BuilderSolid algorithm. If the shapes have been interfered it should contain the images of the source shapes, otherwise its just the original faces. It also contains the faces from <mySBox>.

Fields inherited from BOPAlgo_Builder:

<myArguments> - list of the source shapes. The source shapes can have any type, but each shape must not be self-interfered.

<myShape> - Result shape:

Fields inherited from BOPAlgo_Algo:

<myRunParallel> - Defines whether the parallel processing is switched on or not. <myErrorStatus> - Error status of the operation: 0 - operation successful; 100 - no shapes to process; 102 - BOPAlgo_PaveFiller algorithm has failed; 103 - BOPAlgo_BuilderSolid algorithm has failed.

Example:

BOPAlgo_MakerVolume aMV; // aMV.SetArguments(aLS); //source shapes aMV.SetRunParallel(bRunParallel); //parallel or single mode aMV.SetIntersect(bIntersect); //intersect or not the shapes from <aLS> // aMV.Perform(); //perform the operation if (aMV.ErrorStatus()) { //check error status return; } // const TopoDS_Shape& aResult = aMV.Shape(); //result of the operation
