Re: [osg-users] Loading textured meshes (obj+mtl) leads to crash in osg 3.4.1

['Tom Pollok' via OpenSceneGraph Users]

Hi Laurens,

thank you for clarification! My problem was that im using openscenegraph in 
combination with osgEarth. I figured out how to fix it, so in case other 
osg and osgEarth users might run into the same issue.

To fix the issue i had to include

#include 

and after loading the model i had to run the shader generator on the model.

osgEarth::Registry::shaderGenerator().run( model );

Now everything works fine.

Thank you very much for your super quick help @Laurens and @Robert !!!

Best,
Tom

 So as far as i understand you only add the texture coordinate and 
 normal, if there exists one with a index greater than 0 and less then the 
 number of normals or texture coordinates.
 So that means that openscenegraph now will be able to display the 
 textured mesh, even if the normals are missing, right?

Hi Tom,
Your model works with texture for me, in osg 3.4.0 as well as 3.6.5 with
the following commands:
sed -E "s#(f [0-9]+/[0-9]+)/0 ([0-9]+/[0-9]+)/0 ([0-9]+/[0-9]+)/0#\1 \2
\3#" "Data2.obj" > noNormals.obj
osgviewer -O noRotation  noNormals.obj

Re: [osg-users] Loading textured meshes (obj+mtl) leads to crash in osg 3.4.1

['Tom Pollok' via OpenSceneGraph Users]

Hello Robert,

to test it with my old osg version, i fixed the obj file such it does not 
contain any indices to normals anymore, as there are no normals.
This indeed helped loading the model, but no textures appear at all. Should 
it load the textures automatically due to the first line in the obj file 
being mtllib Data.mtl and the use of usemtl material_0 before the faces or 
do i need to take extra care when loading a textured model?

For loading, im using only:

osgDB::Options* opt = new 
osgDB::Options;opt->setOptionString("noRotation");osg::ref_ptr node 
= osgDB::readNodeFile(pathToObjFile, opt);


Best,
Tom

Yes, that's correct, you'll get a textured mesh with no normals assigned.

The model isn't a valid .obj file, I am not familiar with OpenMVS and as I 
have my own open source projects to manage I'll leave it to others to fix 
OpenMVS.  I would suggest having a look at the .obj export yourself or

I am currently modifying the OSG's obj loader to catch the invalid data as 
crashing is as much as a bug as the dodgy data.  I expect to get a fix 
checked in this afternoon so it'll be part of the OSG-3.6 branch and the up 
coming 3.6.5 release.

I used OpenMVS to create it:

I can also view the model using MeshLab or other tools.

Is it possible to fix the invalid references in openscenegraph?

[Robert Osfield]

I have looked at the model with the 3.6 branch and get the crash and concur 
with Luarens - the model is broken, it has normal indices assigned to the 
faces but no normal array.  The crash occurs because the OSG's obj plugin 
is assuming that if normal indices are provided they are valid normal 
indices.

Where did this model come from?

repost in google group; It seems like my reply to the mailing list does not 
show up in google groups.

Hi Tom,
I think your obj file is invalid, as the faces all reference normal "0" and 
1> no normals are provided
2> normal indices start at 1 (according to wikipedia 
)

if I reduce your obj file to just the first face (removing material and all 
but vertex/texcoord 0-1-2) ( attached )
I get the same crash with
osgconv DataFace1.obj
removing the /0 (normal ref) three times fixes the problem - same works for 
the large file (with textures working)

[Voerman, L.]

Hi Tom,
I think your obj file is invalid, as the faces all reference normal "0" and
1> no normals are provided
2> normal indices start at 1 (according to wikipedia
)

if I reduce your obj file to just the first face (removing material and all
but vertex/texcoord 0-1-2) ( attached )
I get the same crash with
osgconv DataFace1.obj
removing the /0 (normal ref) three times fixes the problem - same works for
the large file (with textures working)

Re: [osg-users] Loading textured meshes (obj+mtl) leads to crash in osg 3.4.1

['Tom Pollok' via OpenSceneGraph Users]

Hello Robert,

I added a minimal reproducer and a stracktrace (release). Unfortunately i 
only have release builds on this machine, but I could provide debug stack 
trace from another system later...

Best,
Tom

Re: [osg-users] Loading textured meshes (obj+mtl) leads to crash in osg 3.4.1

['Tom Pollok' via OpenSceneGraph Users]

I added a zip file with the mesh. It happens when loading that obj file.

https://owncloud.iosb.fraunhofer.de/owncloud/s/dc8dkbXrQz3gTuh

Pw: osg

I have to check for the stack trace again.

osgDB::Options* opt = new 
osgDB::Options;opt->setOptionString("noRotation");osg::ref_ptr node 
= osgDB::readNodeFile(pathToObjFile, opt);

Im using two windows machines with intel processors (64bit). 
OSG was built by ourselves. 
One has an integrated intel graphics unit and one with a Nvidia 2080Ti.

I don;t recall reports of crashes associated with .obj.

Could you provide a link to the model that is causing the problem?

Could you provide a stack trace?

What platform are you working on?  Did you build the OSG yourself?  

What hardware are you working on?

Cheers,
Robert,
