 On Windows platform when using Visual Studio compiler there is a possibility to start the debugger automatically if an exception is caught in a program running OCCT. For this, set environment variable *CSF_DEBUG* to any value. Note that this feature works only if you enable OCCT exception handler in your application by calling *OSD::SetSignal()*.

@section occt_debug_bop Self-diagnostics in Boolean operations algorithm

 In real-world applications modeling operations are often performed in a long sequence, while the user sees only the final result of the whole sequence. If the final result is wrong, the first debug step is to identify the offending operation to be debugged further. Boolean operation algorithm in OCCT provides a self-diagnostic feature which can help to do that step.

@subsection overview_req_graphics Graphic cards

-On desktop, 3D viewer requires graphic card or software implementation supporting OpenGL 1.1 or above. OpenGL 2.1+ is highly recommended.
-Ray tracing requires OpenGL 4.0+ or OpenGL 3.1+ with GL_ARB_texture_buffer_object_rgb32 extension. Textures within ray tracing will be available only when GL_ARB_bindless_texture extension is provided by driver.
-
-On mobile platforms, OpenGL ES 2.0+ is required for 3D viewer. The ray tracing is not yet available on mobile platforms.
-Some old hardware might be unable to execute complex GLSL programs (e.g. with high number of light sources, clipping planes).
+For 3d viewer, graphic card or software implementation supporting OpenGL 1.1 
+or above is required. OpenGL 2.1+ is highly recommended.
+For ray tracing, hardware implementation of OpenCL 1.1+ is required.

nbv	de6d39c92a	0025782: The result of intersection between two cylinders is incorrect 1. Cylinders are tangent to each other indeed. Fix processes this case. 2. Algorithm of intersection line computing (in case of cylinders with two parallel axes) has been changed. Test cases for issue CR25782	2015-03-10 15:08:46 +03:00

nbv	af4b075434	0025465: Excess vertex in the result of CUT operation 1. Methods ClearVertexes(), RemoveVertex(...) and InsertVertexBefore(...) was added to the IntPatch_WLine class. 2. Function IsSame(...) for IntSurf_PntOn2S was added (see IntSurf_PntOn2S.cdl for detail information). 3. Concatenate WLine got if it is possible. Some test cases were changed according to their new behavior.	2014-12-04 10:19:39 +03:00
san	4ece81d4a9	0025528: Visualization - Exception on removing an interactive object from a local context AIS_LocalContext::Remove() corrected to unbind the argument from myActiveObjects at the very end.

gka	a54ca2f54c	0025455: fixshape works at the second attempt Added check and fix of tolerances of all vertices after performing all fixes. It is necessary to avoid situation when point of vertex belonging a few faces was changed for current face but edges containing this vertex belonging before fixed face are not taking into account. Mode FixVertexTolMode to manage check tolerance of vertices was added in ShapeFix_Shape class. (default value is equal to -1) Method to change FixVertexTolMode mode FixVertexTolMode() was added in ShapeFix_Shape class Test case for CR25455	2014-12-04 09:40:40 +03:00
