Re: [osg-users] Rendering a Depthmap

Is there a way to do this directly with osg or does it need a custom implementation? If no, is anybody able to share code for how to render a depthmap with intrinsic camera parameters as a 3d pointcloud using shaders? Am Mittwoch, 12. Juni 2019 21:18:38 UTC+2 schrieb Trajce Nikolov NICK: > > Hi

Re: [osg-users] Textured ply file is black when loaded.

While i agree that it makes no sense for ply to support any application specific formats, I still support the idea of allowing for importing a small subset of possibilities. If the plugin is called osgdb_ply.dll, how should one know that it only supports the semantic of equalizergraphics. Is the

I converted it to ascii using MeshLab https://owncloud.iosb.fraunhofer.de/owncloud/s/KpZFxn5SCm0JFmN pw: osg Yes, using another format is probably a better idea. Do you know which format is typically used that supports binary encoding? Am Dienstag, 21. Januar 2020 15:41:34 UTC+1 schrieb Robert

Hi Robert, oh i didnt mean you to do a deep investigation, i just thought it was a bug or at least you might know if im doing sth wrong. I investigated a little. So it seems that the comment for texture files is actively used: comment TextureFile YourTexture_material_0_map_Kd.jpg So that nee

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, ev

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 the

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" grou
