Re: [osg-users] [osgPlugins] bug stl pugin?
Just to follow up on this, I've confirmed that the behavior we're each seeing is caused by the same bug. The STL plugin for 3.2.0 does not initialize its normal vector array correctly (it reserves all the memory it needs, but only fills in 1/3 of it), which results in undefined behavior. For you it aborts whereas for me it renders badly. It seems that they patched this in version 3.2.1, so if you update to that, the problem should be resolved. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=61512#61512 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgPlugins] bug stl pugin?
This might be related to an issue that I'm currently having. It seems that during the transition from 3.0 to 3.2, binding per primitive was deprecated, but the STL format binds its normal vectors per primitive. To deal with this, there was an ad hoc addition to the STL plugin where the normals of each primitive is being copied and applied to each vertex of the primitive. In theory, this should be fine, but I've noticed that STL files are being rendered incorrectly, and I believe it has to do with the normal vector array being ... wrong somehow. When I print out the data in the normal vector arrays, many of the vectors have invalid magnitudes and look like their memory is uninitialized. It might be the case that something is very wrong about the way the normal array is being stored or initialized. It might be triggering a run time check for you where the program just quits, whereas for me it's just allowing it to be rendered even though the values are corrupted or invalid. But this is all speculation... -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=61500#61500 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgPlugins] bug stl pugin?
Hi Anneke, Quoting Anneke Sicherer-Roetman letter...@hotmail.com: I just installed version 3.2.0. Now, when reading an .stl file with the pretaining plugin, I get vector subscript out of range in the readNode function. I temporarily reverted to 3.0.1 to bve able to continue my work, but what can I do about this?? Could you post a file that exhibits this behaviour?
