Following is a segment from a program while experimenting with those classes. Also to find out if a particular shape is implemented in OSG, I usually refer to HTML documentation (Generated using Doxygen). Just refer to all the classes. ---------------------------------- osg::ref_ptr <osg::MatrixTransform > draw_shape(std::string shape, float x) { /* Geode containing a shape. */ osg::ref_ptr <osg::Geode > geode = new osg::Geode; osg::ref_ptr <osg::ShapeDrawable > sd; if(shape == "box") { osg::ref_ptr <osg::Box > box = new osg::Box(osg::Vec3f(), 5.0); sd = new osg::ShapeDrawable(box.get()); geode- >addDrawable(sd.get()); } else if(shape == "cylinder") { osg::ref_ptr <osg::Cylinder > cylinder = new osg::Cylinder(osg::Vec3f(), 2.0, 5.0); sd = new osg::ShapeDrawable(cylinder.get()); geode- >addDrawable(sd.get()); } else if(shape == "capsule") { osg::ref_ptr <osg::Capsule > capsule = new osg::Capsule(osg::Vec3f(), 2.0, 5.0); sd = new osg::ShapeDrawable(capsule.get()); geode- >addDrawable(sd.get()); } else if(shape == "cone") { osg::ref_ptr <osg::Cone > cone = new osg::Cone(osg::Vec3f(), 2.0, 5.0); sd = new osg::ShapeDrawable(cone.get()); geode- >addDrawable(sd.get()); } else if(shape == "sphere") { osg::ref_ptr <osg::Sphere > sphere = new osg::Sphere(osg::Vec3f(), 2.0); sd = new osg::ShapeDrawable(sphere.get()); geode- >addDrawable(sd.get()); } /* Use matrix tranform to place the object at desired position * from origin. */ osg::ref_ptr <osg::MatrixTransform > mtleft = new osg::MatrixTransform; mtleft- >setDataVariance(osg::Object::STATIC); osg::Matrix m; m.makeTranslate(x, 0.0, 0.0); mtleft- >setMatrix(m); /* Add geode to matrix transform object. */ mtleft- >addChild(geode.get()); return mtleft.get(); } -- Vijay Patil _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
