| Summary | 0007726: Forum 7411: Memory leak with the trihedron display | ||||
| Description | This bug has been reported by Open Source community user Hugues on the Forum, and correction was suggested by Sangsu Lee, see thread 7411: http://www.opencascade.org/org/forum/thread_7411 ------------------------- Hugues: When I set a Z-buffered trihedron in a V3d_View object, memory consumption(pretty huge) of the application grows and grows as the view is rotated, translated, zoomed, etc. Here's the source code I use to tell a V3d_View object to display a red zbuffered trihedron : //construct a V3d_View object ... Handle_V3d_View view = ...; view->TriedronDisplay (Aspect_TOTP_LEFT_LOWER, Quantity_NOC_RED, 0.08, V3d_WIREFRAME); --------------- Sangsu Lee: Hello, I also found that problem, and I believe I found a solution too. I think it is caused by not deleting gldisplaylist used for displaying the triedron. So, you can solve it by simply inserting one line after the end of using those display list. try the below one. in OpenGl_triedron.c .......... ............. glPopAttrib(); /* fleches au bout des axes (= cones de la couleur demandee) */ l = L - L/4. ; /* distance a l'origine */ rayon = L/30. ; /* rayon de la base du cone */ Angle = 2. * M_PI/ NbFacettes; glDeleteLists(startList,4);//by LSS for memery leak bug LightOff(); /* * origine names */ ...... ...... ----------------------- Sangsu Lee: To OCC developers, I think this code can be improved. If we make the display lists only when it is made at first or user redefine the triedron, and just call the lists when redrawing, and destroy it in the v3d_viewer's destructor, it would be more fast and efficient. Currently, it is always recreated and deleted again and it is not so efficient. | ||||
| Additional information and documentation updates | Documentation remark, added by SAN 2005-02-07 11:58:11: Changes: Calling glDeleteLists() was added to call_zbuffer_triedron_redraw() method in OpenGl_triedron.c: ... glPopAttrib(); /* fleches au bout des axes (= cones de la couleur demandee) */ l = L - L/4. ; /* distance a l'origine */ rayon = L/30. ; /* rayon de la base du cone */ Angle = 2. * M_PI/ NbFacettes; glDeleteLists(startList, 4); //added LightOff(); ... | ||||
