Hello, I'm new to the board and have a question about importing CAD models, hopefully someone out there can help. My basic question is this - is there a way to convert or directly import native CAD formats (.stp, .stl, .asm, etc) into OSG, while preserving the model's coordinate frames? I apologize if I'm not using the same terminology. I had searched through your archives without luck.
Here is a little background of where I'm coming from - our team uses OSG to graphically simulate our lab's robot. As the robot is moved by the operator, OSG moves the graphical robot to mimic the physical one. Periodically we need to add another model to the OSG simulator, usually new robotic end effectors. To date, each time we've needed to add a model, we use Solidworks or Pro/E to export the model to VRML format (.wrl). That VRML file is imported into Blender (another open source application you're probably familiar with). Within Blender, we often take time to reduce complexity, or change colors, etc. Then we use Blender to export to OSG format. We then use the matrix transformation information in that OSG file to manipulate the graphics in our simulator. This process works, but the Blender step is very time consuming and seems like it could be bypassed completely. I've tried using osgconv.exe with .obj and .stl files. Both types result in an OSG file which can be viewed, but it lacks the matrix transformation information we need. Please let me know if you can offer any advice. Warning - I am not very OSG savvy. I can use the osgviewer.exe and osgconv.exe, and know basic command line interface operations. Our team has an experienced programmer that owns the OSG side of things. I am the CAD guy and hopefully can communicate any technical OSG information to our programmer. Thanks very much, Brad Lotocki ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=35217#35217 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
