Overview installation and requirements changes updated
1. Instead of the tolerance value of the face the resolution of the surface of the face is used in
the Face Classifier algorithm to define the state of the 2d point relative to that face.
2. Replace the vertices involved in PostTreatFF (treatment of section edges) with their images
(new vertices created in PostTreatFF) in all pave blocks.
3. New value of the result in the test case boolean bsection L8.
Test cases for issue CR24286
Some corrections; test cases were added; coding standards in MFC samples & presentations
Request stencil buffer for Linux.
correct test cases; correct compilation errors
compilation warnings (gcc/Linux)
OpenCL is supported by CMake OCCT solution
3rdparty directory is changed to <occt root>
3rdparty seeking in additional places if 3rdparty dir isn't defined
The purpose of this functionality is to bring a basic ray-tracing solution to existing OCCT visualization toolkit (TKOpenGL).
Currently ray-tracing visualization core supports sharp shadows, specular reflections, transparency and adaptive anti-aliasing.
However, the basis for all ray-tracing algorithms is versatile, allowing you to add new ray-tracing features easily (such as ambient occlusion).
All ray-tracing computations are performed on the GPU using OpenCL framework, allowing real-time rendering performance.
It is important to note, that real-time ray-tracing is possible using high-performance GPUs with support of OpenCL 1.1 and higher (such as NVIDIA GeForce 660 or ATI/AMD Radeon 7850).
When using low-end GPUs (such as NVIDIA GeForce 640) the ray-tracing performance may slow down significantly.
Therefore, even with NVIDIA GeForce 640 you can render scenes with the millions of triangles. The support of OpenCL-enabled CPUs and integrated graphics cards is not guaranteed.
Fixed building by VS 2005 and VS 2013 (Express):
- macro _WIN32_WINNT defined in BOPCol_TBB.hxx for building with TBB on VS 2005
- compiler warnings specific for VS 2005 (vc8) fixed (explicit casts added in assignment expressions involving small integer types)
- definition of functions atanh, acosh, asinh is avoided for vc12 and later (they are provided by CRT in vc12)
- math constants (M_PI and similar) are defined by including math.h rather than by custom code
- misuse of stream operator << fixed in a few places
Eliminated ICC 14 warnings:
# 82: storage class is not first (e.g. "int static f()"
# 2621: attribute "dllexport" does not apply here (e.g. "Standard_EXPORT typedef int qqint;")
# 2415: variable "..." of static storage duration was declared but never referenced
# 111: statement is unreachable (usually "break" after "return" in cycles)
Overall revision of of CSharp sample code:
- Pure C++ project "OCC" deleted as unnecessary
- C++/CLI project "shell" renamed to OCCTProxy and refactored to implement all required interface to OCCT functionality.
- In About dialog, date corrected in Copyright statement
- CSharp files re-layouted with 2 spaces indentation
- ReadMe converted to MarkDown format and revised
- Generation of names of views refactored to avoid calling C++ level
- Project files corrected to run on 64-bit systems
- Batch scripts refactored to use OCCT default configuration
WPF front-end added to demonstrate usage of OCCT in WPF applications.
WPF sample was modified, operation Export has been fixed
Exception "Cannot create this file", which appeared by export to image format, has been corrected.
Option "Export image to .xwd" removed.
New metod was implemented to class BOPAlgo_Builder
- method:
void BOPAlgo_Builder::SetRunParallel(const Standard_Boolean theFlag)
The method sets the flag of parallel processing
if <theFlag> is true the parallel processing is switched on
if <theFlag> is false the parallel processing is switched off
- method:
Standard_Boolean BOPAlgo_Builder::RunParallel()const
The method returns the flag of parallel processing
Class BOPTest was changed
- static function:
Standard_Integer bbuild(Draw_Interpretor& di, Standard_Integer n, const char** a)
The optional parameters [ -s -t ] have been added to the command line of
the command 'bbuild':
bbuild r [-s -t]
-s : builds the result using serial procesing
-t : show the wall time
- method:IntTools_EdgeFace has been changed
Standard_Boolean IntTools_EdgeFace::IsProjectable(const Standard_Real aT) const
The checking the distance between the point on the curve projected point has been added.
IntTools packages were modified
Test cases for issue CR24266
- OpenGl_Display - release GL resources correctly on closing views
- OpenGl_AspectFace, OpenGl_AspectText, OpenGl_AspectLine, OpenGl_AspectMarker - initialize OpenGl resources on demand, when context is available.
- Graphic3d_TextureRoot - use const modifier for GetId method to avoid asynchronous resource state at OpenGl.
- Do not call OpenGL functions if no active GL context has been left
- Reset thread's context before deletion for Mesa WNT
NCollection_Map - add two maps content Exchange operation without data copying
Add Exchange method to NCollection_DataMap, NCollection_DoubleMap, NCollection_IndexedDataMap, NCollection_IndexedMap
Add NCollection_Map::IsEqual() method
Corrections for gcc - use this->myAllocator
changed number of nodes in case of GeomAbs_Line in Extrema_GExtCC::Perform() function.
changed number of nodes in case of GeomAbs_Line in Extrema_GExtCC::Perform().
fixed incorrect indexes and Coeff check in Extrema_CurveCache::Extrema_CurveCache added to avoid int overflow.
Added test case bugs/modalg_5/bug24200
Added check if (aNbS[i] * Coeff[i]) too big in Extrema_GExtCC::Perform().
Fixed several cases of potentially uninitialized variables in Shape Healing.
Corrections to avoid warning for unused variable distmini and to avoid regression for case bug22805
Several corrections coming from building and testing on MSVC++ 11:
- compiler warnings corrected in structiges.c (32-bit mode) and BOPAlgo (64-bit mode)
- DRAW command for testing exceptions (OCC6143) refactored for getting some output even if process fails (problem with stack overflow handling)
- DRAW command readstep removed as it leads to hang-up in Debug mode due to waiting for user input; the only test that used it changed to use testreadstep command
