In the paper we propose a method to determine parameters that appear in algebraic surface blending. By minimizing the surface energy and adding some point restrictions, we can select the free parameters such that a blending surface with reasonable shape is constructed. The method seems to be extensible for other surface blending problems, although we concentrate on algebraic surface blending.

This paper presents a new method for computer-aided molecular design (CAMD) and molecular assembly. A lab-built 5-DOF (degree of freedom) haptic device and the driving computational engine have been developed to provide force-torque feedback to the users for computer-aided molecular design (CAMD). An energy minimization method is proposed for finding collision-free molecular configurations in real-time for molecular docking and assembly. The proposed haptic force-torque feedback provides the users an intuitive tool for understanding the interactions among molecules. The presented techniques can be used in the computer-aided molecular design to provide the scientists or the designers a real-time intuitive guide for manipulating the ligand and understanding of the ligand's behavior towards the binding site of a receptor. computer implementation and illustrative examples are also presented in this paper.

The typical engineering design process can be decomposed into several phases: creative exploration of ideas, testing soundness of proposed concepts, refining concepts to realizable solutions, optimizing viable solutions with respect to performance/cost. Powerful computer algorithms have been developed for many of these tasks. Often these modules are rigid allowing for little intervention by the designer, and the management of the interactions of these tasks mostly relies on human intelligence. Better user interfaces are required to integrate more fully human ingenuity and the assistance of the computer into the overall design process. The most powerful CAD systems should combine the power of programming, graphical visualization, and interactive adjustment of crucial design parameters.
