Eliminate numerical instability by ensuring that the tolerance of intersection entities is slightly grater than the actual distance to the shapes creating the entity.
BRepMesh: Add new mesh parameter *AllowQualityDecrease* which affects the criteria used for checking of the consistency of the existing mesh to new meshing parameters.
So if set to true it will force the meshing of the shape if current deflection strongly vary from the new one, no matter in which side.
BRepTools::Clean: Keep triangulation on non-geometric shapes (faces with no surface or edges with no curves).
Support of CIE Lab and Lch color spaces is introduced in Quantity_Color:
- Enumeration Quantity_TypeOfColor is extended by new values representing CIE Lab and Lch color spaces (with D65 2 deg illuminant).
- Conversion of RGB color to and from these color spaces is implemented in Quantity_Color class (within existing API).
- Color difference calculation using CIE Delta E 200 formula is implemented in method DeltaE2000().
New methods MakeUniformColors() and SetUniformColors() are added in class AIS_ColorScale, generating and setting color scale based on colors of the same lightness in CIE Lch color model.
DRAW commands vcolorconvert and vcolordiff are added to perform conversions and compute difference, respectively.
A new option -uniform is added in DRAW command vcolorscale, to set uniform color scale.
Added test grid v3d colors (color conversions and difference), test bugs vis bug31454 (uniform color scale)
Translation of the entities AXIS2_PLACEMENT_3D including in the entity CONSTRUCTIVE_GEOMETRY_REPRESENTATION_RELATIONSHIP was added.
Entity AXIS2_PLACEMENT_3D is translated to the planar face with axis equal to AXIS2_PLACEMENT_3D.
New parameter "read.step.constructivegeom.relationship" is added to enable this translation (by default it is OFF).
Added test bugs step bug29803
- Added Right() method to BRepFeat_SplitShape;
- Added an option in command buc60854, which allows to select Left() or Right() method;
- Modified method BUC60854 in QABugs_14.cxx;
- Added new option to the help of command buc60854;
- Modified test case buc60854. Now its state is "OK";
- Added check Right() in buc60854 test case.
For small edges fully covered by tolerances of vertices BSpline periodic curves are converted to not periodic BSpline curves by cutting segment before writing.
In the class TopoDSToStep_MakeStepEdge permute of edge vertices for closed curves was added for the case when the range obtained from the vertex projection contradicts the edge range in order to avoid computation of the invalid edge range after reading.
Second test script for bug 0031301
Changes made for #31233 are reverted.
Correction in the ShapeFix_ComposeShell:
Modification of the method SplitByLine in order to find all points of the intersection for case when initial curve shifts in the positive or negative direction
to avoid splitting edge when split point lies in the limits of the tolerance of the vertex.
to correct shift of the pcurves for case when initial shift is more than 1 in the method ShapeFix_ComposeShell::SplitByLine
In the method ShapeFix_Face::FixMissingSeam added removing small edges having length less than working precision and removing wires having area less than working precision
Modified test cases; added test for related issue: bugs step bug31301
In constructor of Geom_RectangularTrimmedSurface, skip check if an offset surface has insufficient continuity. The reason is that this surface has already passed the check once created. So, here we must not apply more strict check than that first time.
Prs3d_Drawer, AIS_Shape, AIS_InteractiveContext - removed properties HLRDeviationCoefficient() and HLRAngle().
Prs3d_Drawer::HLRAngle() is kept as alias to Prs3d_Drawer::DeviationAngle() with deprecated flag.
Prs3d_Drawer::DeviationAngle() default value is changed from 12 to 20 degrees
to match Prs3d_Drawer::HLRAngle() which has been previously used in majority of cases.
Removed unused property HLRBRep_PolyAlgo::Angle().
BRepTools::Triangulation() has been extended with a new parameter for checking Poly_Polygon3D presense within free Edges.
StdPrs_WFShape::Add() now performs auto-triangulation in the same way as StdPrs_ShadedShape::Add().
StdSelect_BRepSelectionTool::GetEdgeSensitive() now creates Select3D_SensitiveSegment instead of Select3D_SensitiveCurve for tessellated segment.
Select3D_SensitiveSegment default sensitivity factor has been changed to 3 pixels to match Select3D_SensitiveCurve.
Test case bug23625_1, added workaround for out-of-range crash in HLRBRep_PolyAlgo on re-triangulated shape.
Use correct ranges of circles when processing the concentric case. Repeat the range comparison 3 times shifting each time for a half-period to process the extrema between boundary points of arcs.
Approx/Approx_SameParameter.cxx,hxx:
Class Approx_SameParameter refactoring. Logic is changed in many places to unify usage, simplify maintenance.
Method Curve2d() is changed to return Geom2d_Curve instead of Geom2d_BSplineCurve. Corresponding message is added to the upgrade guide.
.lxx file is merged into .hxx.
Tangent computation is extracted into special method.
Comparing number of sample points after CheckSameParameter(...) is added to define cases with projection fails.
Undesirable behavior when curves are not same parameterized is fixed.
Geom2dAdaptor/Geom2dAdaptor.cxx: treatment of offset curve is added
Adaptor3d/Adaptor3d_TopolTool.cxx: minor improvement of performance for BSpline surfaces with huge number of knots
Tests were modified according to new behavior of sameparameter algorithm
Get rid of requirement for the arguments of Boolean operations of type CUT and COMMON to be one-dimensional shape. For FUSE operation this requirement is kept.
A case of reading of a very small value was skipped, for example: 2.1219957909652723e-314.
Fixed in XmlMDataStd_RealArrayDriver.cxx and XmlMDataStd_RealListDriver.cxx
// A test file bug29452.xml is extended to check this skipped case.
-Create a new package BRepPreviewAPI, inherited from BRepPrimAPI to create both, valid and degenerative shapes
-Create a new class BRepPreviewAPI_MakeBox for working with a box
Preview can be vertex, edge, rectangle or box
-BRepPrim_GWedge: in the case of non-valid data, the exception does not happen in the constructor, but at the moment of access to the shape
-BRepPrimAPI_MakeBox: myWedge is now not private, but protected, because used in BRepPreviewAPI_MakeBox which inherits from BRepPrimAPI_MakeBox
-Add tests for checking of a creation a preview in tests/geometry/preview (vertex, edge, rectangle, box)
-Update a command "box": add new parameters
Graphic3d_Layer::UpdateCulling() now takes into account BVH_Tree::EndPrimitive().
'vstatprofiler structs' now properly prints number of structures in case of no culling.
- Provide DumpJson for geometrical, ocaf and visualization classes;
- Change depth parameter of DumpJson (constant is not obligate here)
- Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it.
- change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className>
- OCCT_DUMP_* does not require semicolon
- class header is included first in source files of TDataStd, TDocStd, TCAFDoc
Base normal map support has been implemented in path tracing (just geometry normal replacement).
Smooth normal adaptation has been implemeneted in order to avoid black areas artefacts during path tracing.
Tangent normal space calcuation has been moved to separate unified function.
Tangent space orthogonalization algorithm has been changed in order to handle all orientations and combinations of UV coordinates.
The normal after tangent space calculation has been reverted in order to be in right orientation.
The tangent space calculation has been modified in order to handle back faces with inverted normal.
Changes:
- in StepData_StepReaderData::ReadEntity, make sure that entity handle is not null before calling IsKind() of it.
- in StepData_StepReaderData::SetEntityNumbers, do not invert the sign of entity number of referenced parameter if the second pass is not required. Otherwise, the number -1 (obviously invalid) becomes 1 (invalid, but not obviously) without further correction of it.
- in StepData_UndefinedEntity::ReadRecord, consider the case when the entity number is positive but refers to non-existing entity. In this case literal value will be used instead of null entity for the problematic parameter.
"Range" parameter of point light sources (positional and spot) concidering in PBR has been added.
Angular attenuation parameter of spot light in PBR has been reimplemented based on existing "concentration" parameter.
Ray-Tracing now handles IBL and background cubemaps in similar way as PBR.
Ambient light source is handled by Ray-Tracing in similar way as PBR,
e.g. as coefficient for environment map (IBL) or as constant light source.
Test script generating PBR spheres has been moved to Samples
and now shared by PBR and Path-Tracing tests.
