Re: [osg-users] Exporting to SVG from OpenSceneGraph.
Hi again, Yeah, the original question was rendering to Vector SVG (or EMF directly), but osgNVPR definitely looks interesting for other tasks. Thanks for the suggestions regarding GL2PS, but I'm a little bit worried about its dependence on the deprecated OpenGL feedback buffer. I also tried getting an OpenGL-SVG test output from it, and converting that one to EMF, and I had a number of graphical artifact with visible triangle edges and such. I'm currently thinking that the best solution for my specific case will be to recreate the graphs by outputting to Python MatPlotLib and using it for SVG/EMF export, but this is clearly outside the scope of the OSG mailing list. Thanks for the suggestions, and I might still try to integrate the GL2PS solution at some point. Jesper D.

[osg-users] Exporting to SVG from OpenSceneGraph.
Hi guys, I have a question regarding exporting to SVG from OpenSceneGraph. In our software product we use OpenSceneGraph for both a model view window and for a charting component. So far we have exported images from the charting component as bitmap images (by just rendering them to an offscreen pixelbuffer in the required resolution). We have however had some requests for exports from our charting component in a vector format compatible with the Microsoft Office software package (which pretty much means EMF files). Since EMF is very Microsoft-specific, I was thinking of using SVG as an intermediate format, and then using some converter package to create the EMF output. I saw SVG mentioned on the OSG mailing list earlier, but my question is whether there is any way to render to vector SVG from OpenSceneGraph (I kind of expect a hard no here)? The graph contents can be both 2D and 3D graphs and the 3D graphs can contain shaded, but non-textured, 3D-surfaces. Thanks in advance. Jesper D.

Re: [osg-users] Exporting to SVG from OpenSceneGraph.
Hi, AFAIK, osg is not capable to export geometry to SVG. I used gl2ps[1] together with osg to export some geometry to SVG. Worked quite well. cheers, Stephan [1] http://geuz.org/gl2ps/ Am 14.12.11 15:26, schrieb Jesper D. Thomsen: Hi guys, I have a question regarding exporting to SVG from OpenSceneGraph.

The graph contents can be both 2D and 3D graphs and the 3D graphs can contain shaded, but non-textured, 3D-surfaces. Well, OSG can save to a few formats. Explore which ones support saving, and then if you can convert from one of those, through a modeling or conversion tool, into SVG or another 2D vector format. Alternately, if you used a 3D capture tool: http://www.planetpdf.com/creative/article.asp?ContentID=review_adobe_acrobat_3dpage=1 http://www.3d-test.com/interviews/OGLE_1.htm http://www.deep-shadows.com/hax/3DRipperDX.htm you might be able to convert from one of its formats to something you can use. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

The relevant thread is here: http://forum.openscenegraph.org/viewtopic.php?p=42207 The down side, of course, is that you'll be limited to hardware that supports this extension, which is only the more recent nVidia cards (GeForce 8 and later), I believe. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
