The algorithm that builds outlines ("silhouettes") makes an outline in 2d parametric space of the surface starting from some previously detected point where normal is orthogonal to direction of view. So, the surface is previously discretized into (m*n) sample points and some of them become starting points for future outlines.
If the surface has non-uniform parametrization and/or some local extremums of curvature, the outlines can not be built without breaks, so there are several groups of consequent outlines in this case. Unfortunately, it leads to the situation when current number of sample points becomes insufficient to build all the parts of outlines.
The idea is to detect the "holes" between already constructed parts of outlines and then complete the construction.
New auxiliary draw command for testing of HLR.
Correction according to the remarks.
Update of test case according to the developer's directive
Intersection of curves and surfaces in HLRBRep is corrected: parametric limits of face are used instead of parametric limits of surface
Building of outlines (Contap_Contour) is corrected: method ComputeCloseLine is now used in all cases.
Correction of HLRBRep_Surface: usage of UVbounds-option
Correction of test cases according to the new behavior.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Next generic classes:
"Contap_ArcFunction",
"Contap_ContourGen",
"Contap_HContToolGen",
"Contap_HCurve2dToolGen",
"Contap_Line",
"Contap_Point",
"Contap_SurfFunction",
"Contap_SurfProps"
from "Contap" package were converted to the non-generic classes. Names of several classes were changed:
"Contap_Contour",
"Contap_HContTool",
"Contap_HCurve2dTool",
"Contap_Line",
"Contap_Point"
Also all instantiations of the "internal" classes of this classes were moved to the "Contap.cdl". And sources of the "Contap_ContourGen" class were merged to one .cxx file.
Includes of Handle*.hxx headers replaced by include of corresponding class (where possible without redesign of the classes).
Minor correction against compiler warning (vc10 64-bit) in BOPAlgo
Remove double header inclusions
Correction of minor mistake
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
Eliminated warnings -Wswitch shown by gcc
Eliminated two new warnings about wrong initialization order
Eliminated warnings about unused functions.
A few more ICC warnings (type conversions) fixed
Removing pPotentially uninitialized local variable
Got rid of most of warnings C4701: Potentially uninitialized local variable
Removed redundant variable definitions.
Refactored a part of AppParCurves_ResolConstraint CTOR.
Replaced 0. to Precision::Confusion for tolerance vars;
Changed values for min and max parameter vars;
Got rid of redundant variables' initialization.
