基于语义参数的三维复杂模型变形方法研究

Abstract: This paper developed a method about 3D complex models deformation based on semantic parameters to quickly design the 3D complex models, which could solve the problem that 3D models including free-form surfaces have difficult in deformation. This method regarded deformation handles as basic elements, then, by setting the semantic parameters realized the hierarchical deformation: the deformation of components by configuring the deformation handle can make the 3D models redesigned. First, the quadric surfaces replaced the freeform surfaces of each component with Hausdorff distance and the cluster analysis method. Then, the relationship between deformation handles and vertices of each component helped to calculate the constraints of the internal and external components. Finally, editing and modifying the semantic parameters of the deformation handles deformed 3D models. Experimental results which use 3D electrombile as an example show that the above method support users achieve the deformation of 3D models with a few parameters and keep better efficiency of personalized design.
