0026874: Implementation of the Partition operator in OCCT

Browse Source 
1. The partition operation allows splitting an arbitrary number of shapes of an arbitrary dimension
by other arbitrary shapes. The algorithm has been implemented in the class BOPAlgo_Splitter.

The API operator Splitter has been implemented in the class BRepAlgoAPI_Splitter.

2. The draw commands for usage the new algorithm have been implemented - bsplit and bapisplit.
The commands are identical, but one uses the BOPAlgo_Splitter, the other uses BRepAlgoAPI_Splitter.
Both commands should be used after Pave Filler is filled.

3. Test cases for the new algorithm.

4. Documentation has been updated.

Small corrections.

@section occt_algorithms_8 Partition Algorithm
The Partition algorithm is a General Fuse (GF) based algorithm. It provides means to split the group of an arbitrary number of shapes of an arbitrary dimension by the other group of an arbitrary number of shapes of an arbitrary dimension.
All the options of the GF algorithm, such as Fuzzy mode, safe mode, parallel mode, gluing mode and history support are also available in this algorithm.
@subsection occt_algorithms_8_1 Arguments
* The arguments of the Partition algorithms are divided on two groups - *Objects* and *Tools*;
* The requirements for the arguments (both for *Objects* and *Tools*) are the same as for General Fuse algorithm - there could be any number of arguments of any type, but each argument should be valid and not self-interfered.
@subsection occt_algorithms_8_2 Results
* The result of Partition algorithm is similar to the result of General Fuse algorithm, but it contains only the split parts of the shapes included into the group of *Objects*;
* Splits parts of the shapes included only into group of *Tools* are excluded from the result;
* If there are no shapes in the group of *Tools* the result of the operation will be equivalent to the result of General Fuse operation.
@subsection occt_algorithms_8_3 Usage
@subsubsection occt_algorithms_8_3_1 API
On the low level the Partition algorithm is implemented in the class *BOPAlgo_Splitter*. The usage of this algorithm looks as follows:
~~~~~
BOPAlgo_Splitter aSplitter;
BOPCol_ListOfShape aLSObjects = …; // Objects
BOPCol_ListOfShape aLSTools = …; // Tools
Standard_Boolean bRunParallel = Standard_False; /* parallel or single mode (the default value is FALSE)*/
Standard_Real aTol = 0.0; /* fuzzy option (default value is 0)*/
Standard_Boolean bSafeMode = Standard_False; /* protect or not the arguments from modification*/
BOPAlgo_Glue aGlue = BOPAlgo_GlueOff; /* Glue option to speed up intersection of the arguments*/
// setting arguments
aSplitter.SetArguments(aLSObjects);
aSplitter.SetTools(aLSTools);
// setting options
aSplitter.SetRunParallel(bRunParallel);
aSplitter.SetFuzzyValue(aTol);
aSplitter.SetNonDestructive(bSafeMode);
aSplitter.SetGlue(aGlue);
//
aSplitter.Perform(); //perform the operation
if (aSplitter.ErrorStatus()) { //check error status
return;
}
//
const TopoDS_Shape& aResult = aSplitter.Shape(); // result of the operation
~~~~~
@subsubsection occt_algorithms_8_3_2 DRAW
For the usage of the Partition algorithm in DRAW the command *bsplit* is implemented. Similarly to the *bbuild* command (for the usage of the General Fuse algorithm) the *bsplit* command should be used after the Pave Filler is filled.

@subsection occt_algorithms_11a_2 Gluing Operation
The Gluing operation is the option of the Basic Operations, such as General Fuse, Boolean and Section operations.
The Gluing operation is the option of the Basic Operations, such as General Fuse, Partition, Boolean, Section, Maker Volume operations.
It has been designed to speed up the computation of the interferences among arguments of the operations on special cases, in which the arguments may be overlapping but do not have real intersections between their sub-shapes.
This option cannot be used on the shapes having real intersections, like intersection vertex between edges, or intersection vertex between edge and a face or intersection line between faces:
@ -2299,6 +2458,41 @@ Performance improvement from using the GlueShift option in this case is about 70
Performance improvement in this case is also about 70 percent.
@subsection occt_algorithms_11a_3 Safe processing mode
The safe processing mode is the advanced option in Boolean Operation component. This mode can be applied to all Basic operations such as General Fuse, Partition, Boolean, Section, Maker Volume.
This option allows keeping the input arguments untouched. In other words, switching this option on prevents the input arguments from any modification such as tolerance increase, addition of the P-Curves on edges etc.
The option might be very useful for implementation of the Undo/Redo mechanism in the applications and allows performing the operation many times without changing the inputs.
By default the safe processing option is switched off for the algorithms. Enabling this option might slightly decrease the performance of the operation, because instead of the modification of some entitiy it will be necessary to create the copy of this entitiy and modify it. But this degradation should be very small because the copying is performed only in case of necessity.
The option is also availible in the Intersection algorithm - *BOPAlgo_PaveFiller*. Thus, if it is necessary to perform several different operations on the same arguemnts, it is possible to enable the safe processing mode in PaveFiller and prepare it only once and then use it in operations. It is enough to set the option to PaveFiller only and all algorithms taking this PaveFiller will also work in safe mode.
@subsubsection occt_algorithms_11a_3_1 Usage
#### API level
To enable/disable the safe processing mode for the algorithm it is necessary to call the SetNonDestructive() method with appropriate value:
~~~~
BOPAlgo_Builder aGF;

....
// enabling the safe processing mode to prevent modification of the input shapes
aGF.SetNonDestructive(Standard_True);
//

~~~~
#### TCL level
For enabling the safe processing mode for the operaton in DRAW it is necessary to call the <i>bnondestructive</i> command with appropriate value:
* 0 - default value, the safe mode is switched off;
* 1 - the safe mode will be switched on.

//! The class is a General Fuse (GF) based algorithm.<br>
//! It provides means to split an arbitrary number of shapes of arbitrary

//! The arguments of the operation are divided on two groups - Objects

//! The result of the operation contains only the split parts of the Objects.<br>
//! The split parts of the Tools are excluded from the result.<br>
//! If there are no Tool shapes, the operation will be equivalent to General Fuse.<br>

//! All options of the General Fuse algorithm, such as Fuzzy mode, safe mode, parallel

//! The method BOPAlgo_Builder::BuildResult(), which adds the split parts of the arguments
//! into result, does not have to be overridden, because its native implementation
//! performs the necessary actions for the Splitter algorithm - it adds
//! the split parts of only Objects into result, avoiding the split parts of Tools.
