Summary | 0022893: Possible regression in tesselation algorithm of OCCT6.5.2 | ||||
Description | [OCC Forum] Problem with version 6.5.2 (Francesco Argese <francesco.argese@cetma.it>) - http://www.opencascade.org/org/forum/thread_22534/. "Hello, I have noted that version 6.5.2 of OpenCascade has introduced some problems displaying the model taken from here [1]. I cannot attach it here because its size (6.80 MB) is bigger than the maximum allowed size on this forum (2 MB); if you give me an email address that could accept its size I'll send you there. In particular, if you see it using front view of Import/Export app and zooming it with the new version the surface doesn't appear right while with the 6.5.1 and with other CAD softwares it appears right. I have the same problem with my app written with OpenCascade that uses another visualization library so probably the problem could be in the BRepMesh triangulator. Thanks in advance and happy new year! Francesco Argese [1] http://grabcad.com/library/boing-777" ======================= The problem is reproduced on OCCT6.5.2 and not reproduced on OCCT6.5.1. | ||||

The problem becomes more visible on the lateral face of the model. See the attached separate face (lateral_face.brep - s_59) and a picture of the boing. |

Dear Bugmaster, This problem is not reproduced in current version of trank.(It looks fix of bug22781 solved this problem). Number of triangles in problem face for bug22778 is good(2148 triangles; 1135 nodes; max deflection 6.7388607894560643e-005) Please create the new test case for current problem and close the bug. |
