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.
Function Strtod() is reimplemented using open source (MIT-style license) code by David M. Gay instead of strtod() provided by standard run-time library. This improves its performance by 3-10 times.
Functions Atof(), Strtod(), Printf(), Sprintf(), Fprintf() are declared as extern "C" to be usable from C programs.
Strtod() is used in Interface_FileReaderData::Fastof() and in RWStl_Reader to accelerate their work.
DRAW command QATestAtof and test perf fclasses strtod are added to check correctness and performance of Strtod().
Test perf draw restore is added to monitor performance of reading BREP files.
Minor off-topic corrections:
- method Standard_GUID::Assign (const Standard_UUID&) is implemented (was empty);
- Precision.hxx is included in BRepMesh_Vertex.hxx that uses it.
Algorithm of processing cases when point of splitting Walking-line is near to the boundary of the intersection domain but does not match this boundary has been improved.
1. When computing the iso-lines for the face (*DBRep_IsoBuilder*) prepare the Hatching algorithm with the following elements:
a. Trimmed p-curves of edges. The trimming parameters are computed by intersection with p-curves of the neighboring edges. The trimming will be performed only if the intersection point is covered by the tolerance of common vertex.
b. 2D segments connecting the p-curves of the neighboring edges. These segments will close the 2D gaps, which are closed in 3D by the tolerance of vertices shared between edges. This will allow trimming correctly the iso-lines passing through such gaps.
2. Implementation of the additional Init() method for WireExplorer algorithm taking UV bounds of the face to avoid their repeated computation when work working with a face having multiple wires.
3. Test cases for the issue.
Before the fix, BRepAdaptor_CompCurve considered the input wire to be periodic with period LastParameter()-FirstParameter().
Now, method IsPeriodic will always return FALSE because it is impossible to obtain correspondence between the members of BRepAdaptor_CompCurve class and its periodicity status.
New behavior has been documented in upgrade-guide.
In the algorithm math_FunctionRoots, improve the case when it is needed to find the extremum of the function. Earlier, to solve this task the method of gold section was used. With the patch, firstly the algorithm tries to find zero value of the derivative function. In most cases it gives precise result. Secondly, the algorithm tries to find zero value of the function using the old approach. The algorithm chooses the best solution among two computed by different methods.
In the method PutStickPavesOnCurve of BOPAlgo_PaveFiller, forbid putting a vertex to the end of the curve if this end already has a vertex assigned to it. This allows getting rid of unwanted colliding of vertices.
In the method UpdatePaveBlocks of BOPAlgo_PaveFiller, make the check for micro edges more precise.
New category of tests "lowalgos" has been added. Tests for low level algorithms are to be put there. "2dinter" is a new group of tests in this category.
Introduction of the new key for "2dintersect" command, allowing printing the intersection state for each point.
It has the following syntax now:
"2dintersect curve1 [curve2] [-tol tol] [-state]"
Options:
-tol - allows changing the intersection tolerance (default value is 1.e-3);
-state - allows printing the intersection state for each point.
Correct the test case bugs/modalg_7/bug28274 to make proper checks of the result.
Correct procedure of initialization of BRepTopAdaptor_FClass2d and IntTools_FClass2d classifiers so as to produce more tight polygon in the case of self-intersections on very thin faces.
The idea is concluded in checking the condition:
defl < 2 * S / P, where S - is the surface area computed on produced polygon, P - its perimeter, defl - deflection computed on it.
If the condition is not true the polygon is discretized again using QuasiUniformDeflection tool.
In case of sequence of edges based on lines (which are going to be unified into one line-segment), take into account a linear tolerance value.
Get rid of regressions.
Updates of USD-tests.
The issue of incorrect Roots indexing is fixed by changing DataMap to IndexedDataMap.
Draw command fsdread was improved to allow restoring of shapes with kept names.
