Hi. I can't comment on dlopen() usage but here's how i load png texture and apply it to a model: https://github.com/OGStudio/openscenegraph-cross-platform-examples/tree/master/02.TextureImage On Fri, 2 Nov 2018 at 10:10, Jay Maloney wrote: > > I am using the Emscripten build of osg and am running into a problem when I > try to use functions like > Code: > osgDB::readNodeFile > > and > Code: > osgDB::readImageFile > > . > > Usually I get an exception with the message > > > To use dlopen, you need to use Emscripten's linking support, see (cannot > > post links) github ... /kripken/emscripten/wiki/Linking > > > > > The instructions on the page say > > > you must load the side module into the filesystem, so that dlopen (or > > fopen, etc.) can access it. > > > Currently I have in CMakeLists.txt > > Code: > TARGET_LINK_LIBRARIES( > main > osgViewer > osgDB > # osgDB plugins start. > osgdb_osg > osgdb_glsl > osgdb_tga > osgdb_serializers_osg > osgdb_serializers_osgtext > # osgDB plugins end. > osgGA > osgText > osgUtil > osg > osgShadow > OpenThreads > ) > > > > So, does anyone know what is supposed to be done here?

Re: [osg-users] What's the status of .osg files?
Hi Alexandre, Officially .osg and .ive are deprecated in favour of the native serializer baed formats which are .osgt (ascii), .osgb (binary) and .osgx (xml version). The new serializer based formats were introduced in 3.0. While the .osg and .ive formats are deprecated we're not about to remove them from support, the deprecation is more about "don't use" these as they can't support all the functionality that the modern native formats can. For you own project I would recommend moving over to writing .osgt and .osgb by default, and steadily moving over the models you have across.

[osg-users] [forum] Unable to run example (QTCreator, CMake, Windows)
Hello, I have built OSG on my Windows 10 machine and am now trying to run the "osgCMakeExample" example with QTCreator and CMake. No luck! I've defined an environment variable "OSG_ROOT" at my install location, but I receive error messages for each library: "Could NOT find osg (missing: OSG_LIBRARY)" I get the equivalent message for each library. Anyone have any experience getting OSG to build via CMake in QTCreator?

[osg-users] Emscripten build and dlopen
I am using the Emscripten build of osg and am running into a problem when I try to use functions like Code: osgDB::readNodeFile and Code: osgDB::readImageFile . Usually I get an exception with the message > To use dlopen, you need to use Emscripten's linking support, see (cannot post > links) github ... /kripken/emscripten/wiki/Linking > The instructions on the page say > you must load the side module into the filesystem, so that dlopen (or fopen, > etc.) can access it. Currently I have in CMakeLists.txt Code: TARGET_LINK_LIBRARIES( main osgViewer osgDB # osgDB plugins start. osgdb_osg osgdb_glsl osgdb_tga osgdb_serializers_osg osgdb_serializers_osgtext # osgDB plugins end. osgGA osgText osgUtil osg osgShadow OpenThreads ) So, does anyone know what is supposed to be done here? I am able to load .osgt and .osgb nodes but can't load other file nodes or image files like png or tga. Do you have to actually do the loading of the side module, if so which file? The osglib*.a plugins? Is there a way to load files without dlopen?[/code] -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=74970#74970 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Rendering multiple screens
Hi, I'm fairly new to the the osg community but I'm currently trying to create a program that will span over 4 screens (same view different angles).
