Summary0000578: Bug in BRepClass3d_SolidClassifier
DescriptionThis bug has been added by John Swanson at
http://www.opencascade.org/forumorg/bug.php?bug_id=69&status=1 .


Using the latest (as of yesterday) CVS update.

The following snippet of code demonstrates the bug. The point "test_point" as
shown by the sphere is clearly within the sub_etch1 shape, yet the
SolidClassifier reports that it is not.

Code snippet follows:

void CSampleTopologicalOperationsDoc::OnTestShape2()
{
gp_Pnt P0(0,0,0.0);
double xperiod = 1.0;
double yperiod = 1.0;
double sub_thick = 0.5;

myAISContext->EraseAll(Standard_False);

// mask_substrate
TopoDS_Shape substrate = BRepPrimAPI_MakeBox( P0, xperiod, yperiod, sub_thick );

// --------------------------------------------------------------------

// wedge
TopoDS_Shape wedge1 = BRepPrimAPI_MakeWedge(0.5, 0.05, 0.5,
0.1, 0.1 , 0.4, 0.4 );

gp_Trsf rotate = gce_MakeRotation ( gp_Pnt(0.0,0.0,0.0),
   gp_Dir(1.0,0.0,0.0),
1.570795 );

gp_Trsf translate = gce_MakeTranslation(
gp_Pnt( 0.0, -0.5, 0.0),
gp_Pnt( 0.25, 0.25, 0.5)
);

rotate.PreMultiply( translate );

TopoDS_Shape wedge1a = BRepBuilderAPI_Transform( wedge1, rotate );

// --------------------------------------------------------------------

// wedge top
TopoDS_Shape wedge2 = BRepPrimAPI_MakeWedge(0.5, 0.3, 0.5,
0.1, 0.1 , 0.4, 0.4 );

gp_Trsf rotate2 = gce_MakeRotation ( gp_Pnt(0.0,0.0,0.0),
   gp_Dir(1.0,0.0,0.0),
1.570795 * 3.0 );

gp_Trsf translate2 = gce_MakeTranslation(
gp_Pnt( 0.0, 0.0, 0.0),
gp_Pnt( 0.25, 0.25, 0.5)
);

rotate2.PreMultiply( translate2 );

TopoDS_Shape wedge2a = BRepBuilderAPI_Transform( wedge2, rotate2 );


// combine wedges
TopoDS_Shape wedge_common = BRepAlgoAPI_Fuse(wedge1a , wedge2a);

// remove wedge area from substrate
TopoDS_Shape sub_etch1 = BRepAlgoAPI_Cut(substrate, wedge_common);

// --------------------------------------------------------------------

// make deposit layer
gp_Pnt P1(0,0,sub_thick);
double deposit_thick = 0.2;
TopoDS_Shape dep_layer = BRepPrimAPI_MakeBox( P1, xperiod, yperiod,
deposit_thick );

// cut out any intersection w/wedge
TopoDS_Shape dep_layer1 = BRepAlgoAPI_Cut(dep_layer, wedge_common);

// ---------------------------------------------------------------------

// make a wedge/"line" box
    gp_Pln plane1( gp_Pnt(0,0,0), gp_Dir(0,-1,0) );

BRepBuilderAPI_MakePolygon poly;
poly.Add( gp_Pnt(0.4,0,.5) );
poly.Add( gp_Pnt(0.6,0,.5) );
poly.Add( gp_Pnt(0.578,0,.75) );
poly.Add( gp_Pnt(0.422,0,.75) );
poly.Close();

TopoDS_Wire W1 = poly.Wire();

BRepBuilderAPI_MakeFace MKF1(plane1);
MKF1.Add( W1 );
TopoDS_Face FP1 = MKF1.Face();

TopoDS_Wire wprof = BRepBuilderAPI_MakePolygon( gp_Pnt(0.0,0.0,0.0) ,
gp_Pnt(0.0,0.0,1.0) );

TopoDS_Shape boxa = BRepOffsetAPI_MakeEvolved(FP1, wprof, GeomAbs_Arc,
Standard_True, Standard_True, Standard_True );

gp_Trsf translateb = gce_MakeTranslation(
gp_Pnt( 0.0, 0.0, 0.0),
gp_Pnt( 0.0, 1.0, 0.0)
);


TopoDS_Shape boxa1 = BRepBuilderAPI_Transform( boxa, translateb );

// cut get common intersection of line and dep_layer1
    TopoDS_Shape boxa2 = BRepAlgoAPI_Common(dep_layer1, boxa1);

// --------------------------------------------------------------------

// create test point / sphere
gp_Pnt test_point( 0.64, 0.92, 0.1 );
TopoDS_Shape theSphere = BRepPrimAPI_MakeSphere(test_point, .02 );

Handle (AIS_Shape) sphere = new AIS_Shape(theSphere);
myAISContext->SetColor(sphere,Quantity_NOC_YELLOW );
myAISContext->SetMaterial(sphere,Graphic3d_NOM_DEFAULT );
myAISContext->SetTransparency(sphere,_DEF_TRANSPARENCY);
myAISContext->SetDisplayMode(sphere,AIS_WireFrame);
myAISContext->Display(sphere);

// --------------------------------------------------------------------

// display everything
Handle (AIS_Shape) ais5a = new AIS_Shape(sub_etch1);
myAISContext->SetColor(ais5a,Quantity_NOC_BLUE1 );
myAISContext->SetMaterial(ais5a,Graphic3d_NOM_DEFAULT );
myAISContext->SetTransparency(ais5a,_DEF_TRANSPARENCY);
myAISContext->Display(ais5a);

myAISContext->SetColor(ais5b,Quantity_NOC_RED1 );
myAISContext->SetMaterial(ais5b,Graphic3d_NOM_DEFAULT );

myAISContext->SetMaterial(ais5c,Graphic3d_NOM_DEFAULT );

myAISContext->Display(ais5c);

} else {
