1. Added specific header files to disable and restore compiler warnings: Standard_WarningsDisable.hxx, Standard_WarningsRestore.hxx.
(Currently only MSVC compiler is handled.)
2. Inspector: compiler warnings are disabled for all includes of Qt headers.
3. Inspector: minor code correction to avoid warning due to use of floating point values in integer calculations.
OCCT_INSTALL_BIN_LETTER is used only on Windows (isn't depended on type of generator) because bind/libd/bini/libi folders are not used on Linux (only bin and lib)
Method OSD_Process::Spawn() is removed as useless (not used across OCCT or products).
Note that on Linux, macOS, and Windows standard C function "system()" can be used directly instead, while iOS apparently does not support spawning separate processes at all.
AIS_InteractiveContext::MoveTo(), ::Select(), ::ShiftSelect() now throw
an exception on invalid V3d_View argument instead of returning empty results.
AIS_InteractiveContext::DetectedShape() and ::BeginImmediateDraw() now can
be called without opened Local Context.
Draw Harness - removed unused commands vsetam, vunsetam.
Removed unused methods ViewerTest::StandardModeActivation(), ::PickObject(), PickObjects().
Interactive input of Selection modes 0..7 now redirects to vselmode
instead of removed ViewerTest::StandardModeActivation().
Implementation of the 3D model De-featuring algorithm intended for the removal of the unwanted parts (or features) from the model consisting of solids. The features can be the holes, protrusions, gaps, chamfers, fillets etc.
The algorithm removes all possible requested features from the shape and builds the new shape as a result. The input model is not modified.
On the API level the algorithm is implemented in the class *BRepAlgoAPI_Defeaturing*. The actual features removal is performed by the low-level algorithm *BOPAlgo_RemoveFeatures*.
Documentation of the new classes.
Implementation of the DRAW commands for working with new algorithm.
Test cases for the new functionality.
Changes in other algorithms used by De-featuring algorithm:
- Provide history support for the solids in *ShapeUpgrade_UnifySameDomain* algorithm;
- Implementation of the mechanism to merge History of any Algorithm with standard history methods such as IsDeleted(), Modified() and Generated() into *BRepTools_History*.
While UV Iso parameters are obtained in StdPrs_Isolines, UV limits should be applied only if face bounds has infinite values.
In the issue case, the UV values are greater than UVLimits and not infinite. This fix makes possible to have correct Iso lines in presentation without modification of UV limits beforehead.
When measuring the deviation of the end of the added edge from the resulting edge take the point on the curve, not from the vertex.
Test cases for the issue.
Graphic3d_AspectFillArea3d has been extended by new property ::ShadingModel(),
which is set to Graphic3d_TOSM_DEFAULT by default.
The new API allows assigning Shading Model to specific Primitive Array groups
instead of entire Viewer, which was the only possibility before.
Graphic3d_TypeOfShadingModel has been extended with Graphic3d_TOSM_DEFAULT value
meaining that Shading Model defined as default for the Viewer should be used.
Graphic3d_TOSM_NONE has been renamed to Graphic3d_TOSM_UNLIT.
Documentation of Shading Models has been improved by more details.
V3d_TypeOfShadingModel enumeration has been merged into Graphic3d_TypeOfShadingModel
avoiding duplicated definitions and confusion.
Old values has been left for compatibility with old code and can be marked deprecated in future.
Draw Harness command vaspects has been extended by new argument -setShadingModel
for testing Shading Models assigned to entire objects.
OpenGl_SetOfShaderPrograms now holds an array of Shading Models.
OpenGl_ShaderManager interface has been modified and now requires enumeration as input
in several places where Boolean flags have been used previously
(methods ::BindFaceProgram(), ::BindLineProgram(), ::BindMarkerProgram()).
OpenGl_Workspace now defines default (undefined) OpenGl_AspectFace as Graphic3d_TOSM_UNLIT
to simplify indication of primitive groups with undefined Fill Area aspects,
and so that Graphic3d_TOSM_UNLIT set as default Shading Model will not make artifacts on Lines and Markers.
AIS_Manipulator::Axis::Compute() - added missing initialization of Fill Area aspects (leading to undefined behavior).
Now, bounded IntPatch_Points are found in case when starting points are used in intersection algorithm. Before the fix, these points were not looked for (even).
OpenGl_ShaderManager now:
- prefers GLSL ES 100 over GLSL ES 300 on devices reporting OpenGL ES 3.0;
- prefers GLSL ES 300 on devices reporting OpenGL ES 3.1+.
to workaround known buggy implementations of OpenGL ES 3.0 drivers.
Enable multiple draw buffers in shader program only if its required by specific application.
occSetFragColor() - a new GLSL function has been introduced
as an alternative to setting occFragColor/occFragCoverage variables.
ZLayer for Dynamic highlighting of AIS_Point has been set to Graphic3d_ZLayerId_Top
and of Selected highlighting to Graphic3d_ZLayerId_UNKNOWN,
to follow the behavior of normal AIS object.
Custom Graphic3d_Structure implementation has been added to V3d_RectangularGrid and V3d_CircularGrid to trigger recompute in case of device lost.
Primitive arrays are no more (re)computed while grid is not actually displayed.
Boolean Operations - when checking two faces with the same bounds on Same Domain, take into account possible deviation of the edges from the faces surfaces.
Test cases for the issue.
Inherit BRepAlgoAPI_Check class from BOPAlgo_Options instead of BRepAlgoAPI_Algo, as the latter is too excessive for checking purposes.
Implementation of the Draw command "bopapicheck" for testing the BRepAlgoAPI_Check algorithm.
Strengthening of the criteria of the parallel status of the curves by additional checking if the ends of the curves do not diverge.
Test cases for the issue.
The usage of *BRepAlgo_Section* has been replaced with the usage of *BRepAlgoAPI_Section* in *BRepProj_Projection* algorithm.
The TODO statements have been removed from the failing test case in the "prj" grid as they are working correctly now.
The following changes have been made to improve the performance *BRepAlgoAPI_Section*:
1. Revision of the *IntPolyh_Intersection* class to avoid repeated calculation of the deflection of the same triangulation.
2. Small revision of the Edge/Face intersection algorithm to perform Extrema computation on the whole intersection range of the edge instead of discrete ranges.
3. Implementation of the extrema computation for the Circle and Sphere.
4. Correct computation of the parameter of the point on the Circle.
