Hi all, I've got some strange error while trying to compile example file in the directory Tutorials. I've successfully added two New Folders with two Materials into the OpenSG project after the following steps: 1) put New Folder into the Source/Experimental, 2) Remove from the all includes 'O

[Opensg-users] Memory leak in DrawAction ?

Hi all, Is is possible that the DrawAction creates memory leaks ? In our application we load big vrml models with our own vrml-importer. We do the rendering with the DrawAction (dont ask me why). The application runs under Windows. I am using the task manager to watch memory consumption. Exp
