This paper deals with 3D modeling of complex architectural elements for virtual 3D scene reconstruction based on images or point clouds. It presents a new method at the opposite of classical photogrammetry and lasergrammetry techniques: parametric components are created and then adapted to the measured data. We have conceived and developed a parametric shape generator tool for virtual 3D recons...

In the production of mineral raw materials in cupolas, as a by-product and harmful product, significant amount cast iron (up to 3 % material) is formed and, rule, thrown into dumps. The article presents technical solutions that ensure separation melt iron. addition, describes results optimizing design ladders used for draining liquid metal from wool cupola transporting it. resulting ingots can ...
