Detailed Description

Automatic Feature Recognition algorithms of Analysis Situs.

Typedef Documentation

asiAlgo_BadGuid

typedef Standard_GUID asiAlgo_BadGuid

Undefined GUID.

asiAlgo_BlendChain

typedef std::pair<asiAlgo_Feature, asiAlgo_BlendChainProps> asiAlgo_BlendChain

Blend chain.

asiAlgo_BlendTopoConditionMap

typedef NCollection_DataMap<int, Handle_asiAlgo_BlendTopoCondition > asiAlgo_BlendTopoConditionMap

Convenience type alias. Maps ID of a blend face to the data structure which is the descriptor of topological situation around that face.

asiAlgo_Feature

typedef TColStd_PackedMapOfInteger asiAlgo_Feature

Feature as a set of indices of faces.

asiAlgo_FeatureId

typedef int asiAlgo_FeatureId

Feature ID.

asiAlgo_Features

typedef NCollection_DataMap<asiAlgo_FeatureId, asiAlgo_Feature> asiAlgo_Features

Features by indices.

asiAlgo_FeaturesByType

typedef NCollection_DataMap<int, asiAlgo_Features> asiAlgo_FeaturesByType

Handy typedef for indices of feature faces organized by feature types.

asiAlgo_HBlendTopoConditionMap

typedef NCollection_Shared<asiAlgo_BlendTopoConditionMap> asiAlgo_HBlendTopoConditionMap

Shared version of asiAlgo_BlendTopoConditionMap.

Enumeration Type Documentation

asiAlgo_BlendType

enum asiAlgo_BlendType

Blends types.

Enumerator
BlendType_Uncertain	Uncertain blend type for recognizer.
BlendType_Ordinary	Ordinary blend.
BlendType_Vertex	Vertex blend.
BlendType_Cliff	Cliff blend (a special case of ordinary blend).

asiAlgo_BlendVexity

enum asiAlgo_BlendVexity

Blend convexity.

Enumerator
BlendVexity_Uncertain	Uncertain blend vexity.
BlendVexity_Concave	Concave blend.
BlendVexity_Convex	Convex blend.

asiAlgo_FeatureAngleType

enum asiAlgo_FeatureAngleType

Type of angle. Numerical values associated with the items are taken from fundamental paper of Joshi "Graph-based heuristics for recognition of machined features from a 3D solid model", 1988.

asiAlgo_FeatureType

enum asiAlgo_FeatureType

Enumeration for basic feature types.

Enumerator
FeatureType_UNDEFINED	Undefined feature type.
FeatureType_HoleCylindrical	Cylindrical hole.

FeatureType_BlendOrdinary	Ordinary blend.
FeatureType_LAST	Last item is reserved for extensions.

asiAlgo_InsertionType

enum asiAlgo_InsertionType

Type of feature insertion.

Enumerator
InsertionType_Undefined	Undefined type of feature insertion.
InsertionType_Soft	Soft (isolated) feature.
InsertionType_Hard	Hard (non-isolated) feature.

asiAlgo_PartBodyType

enum asiAlgo_PartBodyType

Recognized part types. The type is resolved at the level of a single part body as there could be compound parts which are not recognizable unless exploded to the primitive bodies, such as solids.

Enumerator
PartBodyType_Unrecognized	Pending for recognition.
PartBodyType_FlatShape	Sheet metal body without folds.
PartBodyType_FoldedSheetMetal	Folded sheet metal body.
