Methods

Area(ComWrapper<ICamIpcShapeFaceInfo>)

Face area computed on the tessellation at the build tolerance

Declaration
public static double Area(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
double

BoxMax(ComWrapper<ICamIpcShapeFaceInfo>)

Maximum corner of the face bounding box in model space

Declaration
public static TST3DPoint BoxMax(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
TST3DPoint

BoxMin(ComWrapper<ICamIpcShapeFaceInfo>)

Minimum corner of the face bounding box in model space

Declaration
public static TST3DPoint BoxMin(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
TST3DPoint

CurvatureRatio(ComWrapper<ICamIpcShapeFaceInfo>)

Level-2 (scale-invariant) descriptor: ratio of the smallest to the largest curvature radius, 0..1

Declaration
public static double CurvatureRatio(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
double

GetNormalizedInertia(ComWrapper<ICamIpcShapeFaceInfo>)

Level-2 (scale-invariant) descriptor: principal moments of the face area divided by the largest of them, in ascending order

Declaration
public static TST3DPoint GetNormalizedInertia(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
TST3DPoint

GetVector(ComWrapper<ICamIpcShapeFaceInfo>)

The level-2 descriptor packed for shape recognition. Every value is dimensionless, so the vector does not change with the size of the part

Declaration
public static double[] GetVector(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
double[]

LoopCount(ComWrapper<ICamIpcShapeFaceInfo>)

Number of boundary loops of the face (1 = simple face, 2 and more = face with holes)

Declaration
public static int LoopCount(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
int

MaxCurvatureRadius(ComWrapper<ICamIpcShapeFaceInfo>)

Largest finite radius of curvature of the iso-parametric curves sampled over the face; MaxFloat if no curved direction was found

Declaration
public static double MaxCurvatureRadius(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
double

MinCurvatureRadius(ComWrapper<ICamIpcShapeFaceInfo>)

Smallest finite radius of curvature of the iso-parametric curves sampled over the face; MaxFloat for a planar face

Declaration
public static double MinCurvatureRadius(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
double

SurfaceKind(ComWrapper<ICamIpcShapeFaceInfo>)

Classified analytic kind of the underlying surface

Declaration
public static TCamIpcSurfaceKind SurfaceKind(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
TCamIpcSurfaceKind

VectorSchemaVersion(ComWrapper<ICamIpcShapeFaceInfo>)

Schema version of the feature vector — a classifier trained on one version must not consume another

Declaration
public static int VectorSchemaVersion(this ComWrapper<ICamIpcShapeFaceInfo> infoCom)
Parameters
Type Name Description
ComWrapper<ICamIpcShapeFaceInfo> infoCom
Returns
Type Description
int
