Re: [osg-users] iOS: wireframe
I think it could be useful in many other scenarios, regarding the current one, at last, requirements changed so I had not to use wireframe anymore. If you don't mind it would be great to have the chance to try it. By the way, is your implementation intended for GLES? Thanks.

[osg-users] iOS: wireframe
Hi, I'd like to set the visualization mode to wireframe on iOS, I use these instructions: Code: osg::ref_ptrosg::StateSet ss = myModelNode-getOrCreateStateSet(); osg::ref_ptrosg::PolygonMode pm; pm = new osg::PolygonMode(osg::PolygonMode::FRONT_AND_BACK, osg::PolygonMode::LINE); ss-setAttributeAndModes(pm.get(), osg::StateAttribute::ON | osg::StateAttribute::OVERRIDE); but when the app is running and 'myModelNode' is shown, I keep getting this warning: ... Warning: PolygonMode::apply(State) - not supported. ... and, of course, the model is drawn as if it is NOT in wireframe. Am I doing something wrong? Is really PolygonMode not supported on iOS? If so, how can I change to wireframe mode? Thanks for your help.

If so, how can I change to wireframe mode? I suspect glPolygonMode is not supported in any flavor of OpenGL ES. http://www.khronos.org/opengles/ ...but you should check the spec. You could change to wireframe mode using a switch and a second scene graph that renders your geometry as lines. I don't know of an automated way to create such a scene graph; you might have to write a NodeVisitor to create that for you. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I checked the spec. glPolygonMode is not supported by OpenGL ES. That was a surprise to me as well. It is still part of the core profile in OpenGL 3.1 and higher. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
