Detailed Description

The class is a General Fuse algorithm - base algorithm for the algorithms in the Boolean Component. Its main purpose is to build the split parts of the argument shapes from which the result of the operations is combined.
The result of the General Fuse algorithm itself is a compound containing all split parts of the arguments.

Additionally to the options of the base classes, the algorithm has the following options:

Safe processing mode - allows to avoid modification of the input shapes during the operation (by default it is off);
Gluing options - allows to speed up the calculation of the intersections on the special cases, in which some sub-shapes are coinciding.
Disabling the check for inverted solids - Disables/Enables the check of the input solids for inverted status (holes in the space). The default value is TRUE, i.e. the check is performed. Setting this flag to FALSE for inverted solids, most likely will lead to incorrect results.

The algorithm returns the following warnings:

BOPAlgo_AlertUnableToOrientTheShape - in case the check on the orientation of the split shape to match the orientation of the original shape has failed.

The algorithm returns the following Error statuses:

BOPAlgo_AlertTooFewArguments - in case there are no enough arguments to perform the operation;
BOPAlgo_AlertNoFiller - in case the intersection tool has not been created;
BOPAlgo_AlertIntersectionFailed - in case the intersection of the arguments has failed;
BOPAlgo_AlertBuilderFailed - in case building splits of arguments has failed with some unexpected error.

◆ BuildBOP() [1/2]

virtual void BOPAlgo_Builder::BuildBOP	(	const TopTools_ListOfShape &	theObjects,
		const TopAbs_State	theObjState,
		const TopTools_ListOfShape &	theTools,
		const TopAbs_State	theToolsState,
		Handle< Message_Report >	theReport = `NULL`
	)

virtual

Builds the result shape according to the given states for the objects and tools. These states can be unambiguously converted into the Boolean operation type. Thus, it performs the Boolean operation on the given groups of shapes.

The result is built basing on the result of Builder operation (GF or any other). The only condition for the Builder is that the splits of faces should be created and classified relatively solids.

The method uses classification approach for choosing the faces which will participate in building the result shape:

All faces from each group having the given state for the opposite group will be taken into result.

Such approach shows better results (in comparison with BOPAlgo_BuilderSolid approach) when working with open solids. However, the result may not be always correct on such data (at least, not as expected) as the correct classification of the faces relatively open solids is not always possible and may vary depending on the chosen classification point on the face.

History is not created for the solids in this method.

To avoid pollution of the report of Builder algorithm, there is a possibility to pass the different report to collect the alerts of the method only. But, if the new report is not given, the Builder report will be used. So, even if Builder passed without any errors, but some error has been stored into its report in this method, for the following calls the Builder report must be cleared.

The method may set the following errors:

BOPAlgo_AlertBuilderFailed - Building operation has not been performed yet or failed;
BOPAlgo_AlertBOPNotSet - invalid BOP type is given (COMMON/FUSE/CUT/CUT21 are supported);
BOPAlgo_AlertTooFewArguments - arguments are not given;
BOPAlgo_AlertUnknownShape - the shape is unknown for the operation.

Parameters:

Parameters

theObjects	- The group of Objects for BOP;
theObjState	- State for objects faces to pass into result;
theTools	- The group of Tools for BOP;
theObjState	- State for tools faces to pass into result;
theReport	- The alternative report to avoid pollution of the main one.

◆ BuildBOP() [2/2]

void BOPAlgo_Builder::BuildBOP	(	const TopTools_ListOfShape &	theObjects,
		const TopTools_ListOfShape &	theTools,
		const BOPAlgo_Operation	theOperation,
		Handle< Message_Report >	theReport = `NULL`
	)

inline

Builds the result of Boolean operation of given type basing on the result of Builder operation (GF or any other).

The method converts the given type of operation into the states for the objects and tools required for their face to pass into result and performs the call to the same method, but with states instead of operation type.

The conversion looks as follows:

COMMON is built from the faces of objects located IN any of the tools and vice versa.
FUSE is built from the faces OUT of all given shapes;
CUT is built from the faces of the objects OUT of the tools and faces of the tools located IN solids of the objects.

Parameters

theObjects	- The group of Objects for BOP;
theTools	- The group of Tools for BOP;
theOperation	- The BOP type;
theReport	- The alternative report to avoid pollution of the global one.

Prepare history information for the input shapes taking into account possible operation-specific modifications. For instance, in the CellsBuilder operation, additionally to splitting input shapes the splits of the shapes (or the shapes themselves) may be unified during removal of internal boundaries. In this case each split should be linked to the unified shape.

To have correct history information, the method should be redefined in each operation where such additional modification is possible. The input shape <theS> should be the one from arguments, and the returning list should contain all final elements to which the input shape has evolved, including those not contained in the result shape.

The method returns pointer to the list of modified elements. NULL pointer means that the shape has not been modified at all.

The General Fuse operation does not perform any other modification than splitting the input shapes basing on their intersection information. This information is contained in myImages map. Thus, here the method returns only splits (if any) contained in this map.
