Re: [osg-users] MacOSX/Core Profile: Attribute aliasing behavior ?
Hi In core context, osg wraps deprecated arrays (Vertex,Normal) to vertex array attributes that's why a few are reserved for this purpose (VertexArrayAttrib 0 to 5 If i remember). It can appears wrong but it's the choice made to preserve both gl compatibility and osg semantic.

Re: [osg-users] MacOSX/Core Profile: Attribute aliasing behavior ?
Sorry but it seams to me the question was answered a lot of time on the forum.. core gl context have dropped the standard fixed pipeline so in core context glsl you must define all your variable as old built-in (gl_XXX) have been removed. osg wraps them in osg_XXX but you may define your own vertex attribute array and use Program::addBindAttributeLocation to connect to your Shader Cheers remoe wrote: > Julien, thanks for your hint, but i don't know what you mean :) I've look at > this sample: > > https://github.com/openscenegraph/OpenSceneGraph/blob/master/examples/osgsimplegl3/osgsimplegl3.cpp > > > Cheers, > Remo Twirling twirling twirling toward freedom -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=74449#74449 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Julien, thanks for your hint, but i don't know what you mean :) I've look at this sample: https://github.com/openscenegraph/OpenSceneGraph/blob/master/examples/osgsimplegl3/osgsimplegl3.cpp Cheers, Remo -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=74448#74448 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

With core profile you must use strict syntax... see simpleGL3 example remoe wrote: > Hi folks, > > Can someone please explain me why OpenGL on MacOSX (Core Profile 4.1) throw > the following error: > > > Code: > ERROR: Active attribute aliasing.

[osg-users] MacOSX/Core Profile: Attribute aliasing behavior ?
Hi folks, Can someone please explain me why OpenGL on MacOSX (Core Profile 4.1) throw the following error: Code: ERROR: Active attribute aliasing. Slot 3 unavailable for 'osg_MultiTexCoord0' from BindAttributeLocation request. on the following sample: https://github.com/remoe/osgsample-2 When one remove the default shader from OSG: https://github.com/remoe/osgsample-2/blob/master/main.cpp#L205 with "#if 0", Then it doesn't throw an error on MacOSX. This sample doesn't throw an error on windows. Thank you!
