Dear All,
I'm trying to create arbitray shape by manually entering the vertices normals
and indices of object. For this I use the following pseudo algorithm for object
creation, but the resulting shape edges are not discernible as shown in the
attached snapshot (marked with purple ellipse).
Also manually created object is not recognized by the Intersectors while the
"T" shaped object is recognized.
osg::Node * CreatObject(){ // VERTICES osg::Vec3Array* obj_vertices =
new osg::Vec3Array; obj_vertices->push_back(osg::Vec3d(-3.0000, 4.0000,
-0.0000)); ...... /// NORMALS osg::Vec3d vec1, vec2, vec3;
osg::ref_ptr<osg::Vec3Array> normals = new osg::Vec3Array; vec1[0] = 0;
vec1[1] = 0; vec1[3] =-1; ....
normals->push_back(vec1);normals->push_back(vec1);normals->push_back(vec1);normals->push_back(vec1);
normals->push_back(vec1);normals->push_back(vec1);normals->push_back(vec1);normals->push_back(vec1);
normals->push_back(vec1);normals->push_back(vec1);normals->push_back(vec1);normals->push_back(vec1);
............
// INDICES osg::ref_ptr<osg::Geometry> geom = new osg::Geometry;
geom->setVertexArray( obj_vertices ); geom->addPrimitiveSet( indices.get()
); geom->setNormalArray(normals.get());
geom->getOrCreateStateSet()->setMode(GL_RESCALE_NORMAL,osg::StateAttribute::ON);
geom->setNormalBinding(osg::Geometry::BIND_PER_VERTEX);
osgUtil::SmoothingVisitor::smooth( *geom ); osg::ref_ptr<osg::Geode>
I_object = new osg::Geode; I_object->addDrawable( geom.get() );
scene_ALL->addChild(I_object);} _______________________________________________
