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

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

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

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 Laurens. On Wed, Jan 15, 2020 at 12:24 PM 'Tom

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

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

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

Thank you for the workaround. 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,

I have checked in a workaround for the invalid indices to the 3.6 branch and master: https://github.com/openscenegraph/OpenSceneGraph/commit/2b9c501e18b6eded7375c0e272aff401ad9793a2 -- You received this message because you are subscribed to the Google Groups "OpenSceneGraph Users" group.

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

I used OpenMVS to create it: https://github.com/cdcseacave/openMVS I can also view the model using MeshLab or other tools. Is it possible to fix the invalid references in openscenegraph? Am Dienstag, 14. Januar 2020 14:36:29 UTC+1 schrieb Robert Osfield: > > I have looked at the model with

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

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

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 =

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

When loading a textured mesh from an obj file with mtl + texture file, openscenegraph crashes. I use openscenegraph 3.4.1. Does anybody know if that issue has been fixed in newer versions? -- You received this message because you are subscribed to the Google Groups "OpenSceneGraph Users"
