Summary0027383: Modeling - improve handling of regularity on edges
DescriptionIn OCCT, edge can have a "regularity" flag indicating continuity of the shape surface across this edge. This flag is associated to two faces that are connected at the edge. It is returned by method BRep_Tool::Continuity() (and stored internally either as separate representation (BRep_CurveOn2Surfaces), or as a flag in BRep_CurveOnClosedSurface).

This flag is helpful for some algorithms that need to know continuity of connection between the faces, e.g. in construction of fillets and other local features. The most noticeable use of this flag is in HLR algorithm: it does not show edges with continuity C2 or greater since these edges do not represent recognizable line on a shape surface (example is seam on a pipe) and thus have no special meaning for an engineer. (The same logic can naturally be used when displaying shaded shape with wireframe edges.)

Most algorithms that generate shapes in OCCT directly seem to set this flag appropriately basing on the nature of the algorithm and input data. However in shapes coming from external sources (Data Exchange) or generated by complex algorithms (such as surface reconstruction) the regularity has to be determined by analysis of the geometry of connected faces.

OCCT provides method BRepLib::EncodeRegularity() aimed to analyze the edges and set regularity for those where continuity is greater than C0 (C0 is assumed by default if not set). In context of #27272, some deficiencies of current implementation of BRepLib::EncodeRegularity() and its usage across OCCT code have been identified, listed here:

1. Performance issues:

a) If called for compound representing assembly that can contain several instances of the same shape (e.g. solid) with different locations, BRepLib::EncodeRegularity() will process each instance. The improvement to avoid this is available in ShapeFix::EncodeRegularity(); it should be merged into BRepLib::EncodeRegularity() instead of being separate method.

b) In context of operation that modifies some edges on existing shape (such as ShapeFix or conversion routines), there is no (convenient) way to enforce recalculation of regularity only for edges that have been changed. An API accepting collection of edges to be updated could be provided to address this need. Alternatively, some logic can be applied involving shape flags such as Locked or Modified (see TopoDS_TShape).

2. Limitation

BRepLib::EncodeRegularity() can set only C0 and G1 continuity in general case (#27272 adds possibility to set CN for seam edges on elementary surfaces). It does not set C2 or higher continuity even at connections of faces built on the same smooth surface. The examples are edges produced by Boolean operations or by splitting existing faces:

# fuse of two boxes
pload MODELING
box b1 10 10 10
box b2 5 5 0 10 10 10
bfuse r b1 b2
explode r f
explode r_7 e
getedgeregularity r_7_3 r_3 r_7 ;# returns C0: regularity is not set at all
encoderegularity r
getedgeregularity r_7_3 r_3 r_7 ;# returns G1: better but should be CN

# split of cylinder
pload MODELING
pcylinder p 2 10
DT_SplitAngle r p
explode r f
explode r_1 e
getedgeregularity r_1_2 r_1 r_2 ;# returns C0: regularity is not set at all
encoderegularity r
getedgeregularity r_1_2 r_1 r_2 ;# returns G1: better but should be CN

All these edges will be considered as non-smooth and in particular shown by HLR:

pload VISUALIZATION
vdisplay r
vfit
vhlr on


3. Inconsistent use

a) Boolean operations and Shape Healing algorithms do not set regularity on edges (see examples in point 2 above). This should be at least documented (a need to call EncodeRegularity() afterwards).

b) Class BRepBuilderAPI_Sewing calls BRepLib::EncodeRegularity() for an edge argument; this obviously does nothing since this function analyzes edges by faces

4. Documentation currently seems to lack explanation of what regularity is and how it is used

    1. There has been implemented calculation of all possible types of continuity for shared edges:
      * G1 is set if tangential planes are the same for connected faces in each control points through the edge;
      * C1 is set in addition to G1 conditions if derivatives, orthogonal to the edge on each face, are equal vectors;
      * G2 is set in addition to G1 if the centers of principal curvatures are the same for connected faces in each control points through the edge;
      * C2 is set in addition to C1 and G2 if directions of principal curvatures are equal;
      * CN continuity is set only if both connected faces are based on elementary surfaces (the conditions for this case are similar to C2 continuity).
    
    2. ShepFix::EncodeRegularity() is merged into BRepLib::EncodeRegularity().
    
    3. Implemented several test cases to check correct handling of regularity.

- at 1725, why directions are not reversed, but lengths are reversed? It seems to be more natural reverse directions and make lengths positive. In this case the conditions at lines 1892 and 1893 can be omitted, and comparison of lengths at 1887 and 1889 becomes more consistent.
- at 1773, 1775, variables can be declared const &, if provide a separate variable for location of the second surface.
- the code 1837-1845 can be simplified using BRepAdaptor_Curve(E,F) and BRepAdaptor_HCurve. The variable aCurveForExtr can be of type Adaptor3d_HCurve.
- the condition on line 1818 is always false due to condition of loop at 1813.
- if you declare that you compare derivative vectors, why did you leave old check of normal directions? Can we drop it now?
- in 1864 in fact sine of angle is compared with confusion. Why theAngleTol is not used?
- in 1867 difference of squares is used instead of square of difference. It is incorrect.
- in 1868 scalar product of non-unified vectors is compared with confusion. Why?
- the line 1872 can be replaced with "return GeomAbs_C0", and check in 1874 is not needed.

Documentation:
I think "Regularity of Shared Edges" is to be moved to Modeling Data, as a next section after description of continuity.
Remarks to this section:
- two faces shared this edge => two faces sharing this edge
- Changing of edge's regularity is performed by BRep_Builder::Continuity method
=>
  Edge's regularity can be set by BRep_Builder::Continuity method
- results of other algorithms (Boolean Operations, Shape Healing, etc.) lose information about regularity
=>
  other algorithms (Boolean Operations, Shape Healing, etc.) do not set regularity.
- To improve this situation, BRepLib package provides method EncodeRegularity, which calculates and sets correct values for all edges of the shape.
=>
  If regularity is needed to be correctly set on a shape, the method BRepLib::EncodeRegularity can be used, which calculates and sets correct values for all edges of the shape.
- The example above shows that the edge shared by cylinder and sphere after boolean operation has C0 continuity.
This is wrong, as the example does not evaluate continuity after fuse.

Dear Mikhail,

Please review branch CR27383_1.

I would like just to comment some of your questions:

Q: at 1725, why directions are not reversed, but lengths are reversed? It seems to be more natural reverse directions and make lengths positive. In this case the conditions at lines 1892 and 1893 can be omitted, and comparison of lengths at 1887 and 1889 becomes more consistent.
A: The direction does not matter for the curvature. Along the same direction the curvature may be different (positive/negative/zero) for different kinds of surfaces. Directions of the principal curvatures are calculated here to check that the curves of maximal/minimal curvature on the connected faces are the same.

Q: in 1868 scalar product of non-unified vectors is compared with confusion. Why?
A: It is just checking that the vectors are codirectional. I have added comment into the code concerning this.

Committer: apn Details Diff		 0027383: Modeling - improve handling of regularity on edges

1. There has been implemented calculation of all possible types of continuity for shared edges:
* G1 is set if tangential planes are the same for connected faces in each control points through the edge;
* C1 is set in addition to G1 conditions if derivatives, orthogonal to the edge on each face, are equal vectors;
* G2 is set in addition to G1 if the centers of principal curvatures are the same for connected faces in each control points through the edge;
* C2 is set in addition to C1 and G2 if directions of principal curvatures are equal;
* CN continuity is set only if both connected faces are based on elementary surfaces (the conditions for this case are similar to C2 continuity).

2. ShapeFix::EncodeRegularity() is merged into BRepLib::EncodeRegularity().
3. Implemented several test cases to check correct handling of regularity.
4. Fix incorrect usage of BRepLib::EncodeRegularity() in BRepBuilderAPI_Sewing.
5. Implement a method for calculation of regularity on the given list of edges.
