................................. osg::ref_ptr<osg::Vec3Array> mVertexs; mDrawArray = new osg::DrawArrays(osg::PrimitiveSet::POINTS,0,0);
// Modify vertex array (mVertexs is in app side). mVertexs->push_back( vertex ); // Tell OSG geometry was modified. mGeometry->setVertexArray( mVertexs.get() ); mGeometry->dirtyDisplayList(); mDrawArray->setCount( mVertexs->size() ); ................................. Nevermind. So this code is doing a component-by-component update after vertexs were modified. This is correct afterall. Was wondering why OSG has no higher-level osg::Geometry::dirty(). But since Geometry is composed of PrimitiveSets/DrawArrays with APP-DEFINED indexs/count into the vertex array, of course the app (not OSG) has to update components. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
