Summary | 0009520: Memory leak in vtkUnstructuredGridBunykRayCastFunction | ||||||||
Description | When using a vtkUnstructuredGridVolumeRayCastMapper to render a volume with vtkUnstructuredGridBunykRayCastFunction there is a memory leak. The leak occurs when something before the mapper in the pipeline is modified and a render requested. vtkUnstructuredGridBunykRayCastFunction::UpdateTriangleList will be called during the render, it will allocate vtkUnstructuredGridBunykRayCastFunction::TetraTriangles - but not delete the one that had been allocated on the previous call. I have supplied c++ source to reproduce the leak, and a patch. When the source is compiled and the process will consistently leak ram. Be careful running it for long, it will 100% the cpu and uses up all the ram it can over time. | ||||||||

Which version of VTK are you using? (a release ? CVS head ?) |
(0017549) Luke Dodd (reporter) 2009-09-15 19:51 |
This is present in vtk 5.4.2. It seems to be fixed in CVS head that I just tested. (I tested my larger program against CVS head before and it had memory issues - it didn't show up in the smaller example I uploaded. Most likely a fault somewhere else in my code clouding the issue.) This revision seems to be the fix: http://public.kitware.com/cgi-bin/viewcvs.cgi/VolumeRendering/vtkUnstructuredGridBunykRayCastFunction.cxx?r1=1.6&r2=1.7 [^] Sorry for any time wasted! |

I asked because I'm the person who actually applied the patch on VTK CVS head in April in rev 1.7 of vtkUnstructuredGridBunykRayCastFunction.cxx. Don't be sorry because this is an opportunity to apply the patch to the release branch. Thanks for the report. |
