Summary	0023886: Visualizing planar faces with "notches" depends heavily on the deflection coefficient
Description	Attached some sample BREP files with affected planar faces (they seem to be valid). If the deflection coefficient is too big the faces are visualized incorrectly in the shaded mode. On the attached pictures it can be seen what deflection values were used for each face.
Steps To Reproduce	pload ALL restore face_01.brep s vinit vdisplay s vfit vsetdispmode s 1 vsetshading s 0.00001 vsetshading s 0.01
Tags	No tags attached.

~~abv~~ 2013-04-12 15:43 manager ~0024119	I guess there is an option to define angular deflection which can help getting better result while keeping linear deflection reasonably high...

~~abv~~ 2014-09-26 12:16 manager ~0032215	The problem can be avoided by setting appropriate angular deflection, e.g.: vdefaults angDefl=1 I propose adding a test case and closing the issue

~~mkv~~ 2014-10-09 10:34 tester ~0032861	Dear BugMaster, Test cases bugs/vis(004)/bug23886_1,bug23886_2,bug23886_3 is created and pushed to new branch CR23886 of occt git-repository. Test cases bugs/vis(004)/bug23886_2,bug23886_3 are OK. http://occt-tests/master-CR25323-occt/Debian60-64/bugs/vis/bug23886_2.html http://occt-tests/master-CR25323-occt/Windows-32-VC10/bugs/vis/bug23886_2.html http://occt-tests/master-CR25323-occt/Debian60-64/bugs/vis/bug23886_3.html http://occt-tests/master-CR25323-occt/Windows-32-VC10/bugs/vis/bug23886_3.html Test case bugs/vis(004)/bug23886_1 have different images. Dear abv, it is normal? http://occt-tests/master-CR25323-occt/Debian60-64/bugs/vis/bug23886_1.html http://occt-tests/master-CR25323-occt/Windows-32-VC10/bugs/vis/bug23886_1.html

~~abv~~ 2014-10-09 10:43 manager ~0032865	Yep, it is normal that images are different for different deflections used

~~mkv~~ 2014-10-09 13:37 tester ~0032882	OK.

oan 2014-10-13 10:48 developer ~0033002 Last edited: 2014-10-13 10:50	Dear MKV, please remove line vdefaults angDefl=1 from test cases, use test script provided by reporter and run tests again. Bug should be solved using functionality from 0024959 without any cheats.
