[osg-users] Using Light without LightSource in OSG 3.4.0
Hi,
I want to add light to my scene and I want the different light which have same
Number can be used at the same time.Thus , I use light as a Attribute to set it
to stateset. There is no problem when the model is not rotate.But when model is
rotated, the light seemed rotated by the matrix.There is my source code:
int main()
{
osg::ref_ptr root = new osg::Group;
osg::ref_ptr light = new osg::Light;
light->setLightNum(0);
light->setPosition(osg::Vec4(0, 0, 1, 0));
light->setAmbient(osg::Vec4(0,0, 0, 1));
light->setDiffuse(osg::Vec4(0, 1, 0, 1));
light->setSpecular(osg::Vec4(1, 0, 0, 1));
auto stateSet = root->getOrCreateStateSet();
stateSet->setAttributeAndModes(light);
osg::ref_ptr hints = new osg::TessellationHints;
hints->setDetailRatio(0.1);
osg::ref_ptr geode1 = new osg::Geode;
osg::ref_ptr shape1 = new osg::ShapeDrawable(new
osg::Box(osg::Vec3(0, 0, 0), 10, 10,10), hints.get());
geode1->addDrawable(shape1);
osg::ref_ptr geode2 = new osg::Geode;
osg::ref_ptr shape2 = new osg::ShapeDrawable(new
osg::Box(osg::Vec3(20, 20, 20), 10, 10, 10), hints.get());
geode2->addDrawable(shape2);
osg::ref_ptr mt = new osg::MatrixTransform;
osg::Matrix mat;
mat = mat.rotate(180, osg::Vec3(0, 1, 0));
mt->setMatrix(mat);
mt->addChild(geode2);
root->addChild(mt);
root->addChild(geode1);
osgViewer::Viewer myViewer;
myViewer.setSceneData(root);
myViewer.run();
return 0;
}
So,is it the light can be used without LightSource?
Thank you!

Re: [osg-users] [build] Building OpenSceneGraph Windows
Hi, all. Sorry for this very long time to reply. The %PATH% Variables were the solution of my problem. OpenSceneGraph is just building at the moment with MSYS. Thank you for this Christian Schulte. Also the tutorial of kornerr was helpful for my understanding. I am very happy that OSG is building at the moment. It takes quite a while but so ;). But now I have a new question. I got this messages in my log file. Should I be concerned about those and what exactly do they mean? Espacially with the ZLIB missing, JPEG missing, PNG missing Thank you again for your support. I am really happy. Thank you!

Re: [osg-users] New glTexStorage code is disrupting FBO initialization
Robert, Seems to be working now. Yesterday I submitted a PR to change GL_RGBA16F and GL_RGBA32F to GL_RGBA16F_ARB and GL_RGBA32F_ARB, but you only changed GL_RGBA32F. Both are undefined on Windows so I re-submitted a PR to get the Windows build building again.

Re: [osg-users] New glTexStorage code is disrupting FBO initialization
Hi Robert, I had the same issue with the FBO failing to initialize. Works now with the master.

[osg-users] OpenSceneGraph-3.6-TexStorage branch created, needs community testing :-)
HI All, I have created a OpenSceneGraph-3.6-TexStorage branch to allow glTexStorage support that was just in the master branch to be ported back onto 3.6. There isn't any public API changes so it should drop in OK compile wise, runtime wise it's a different matter though. We need testing across a wide range of platforms/hardware and application usage cases to know whether this change is safe. If it all looks OK then I'll merge 3.6-TexStorage into the main 3.6 branch and then we can start working towards a 3.6.3 release in September. So please test if you can. Many thanks, Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Glenn, We have had a bash at resolve this issue. Could you please try out OSG master or the OpenSceneGraph-3.6-TexStorage branch to see if this issue still exists.
