Virtual Clay Modeling
虚拟油泥造型方法

There are three modeling methods in the virtual clay modeling system, which are cutting, pasting and cutting-pasting operations. To realize these methods, the swept volume should be built by the shape and position from a moving modeling tool, and discrete it into uniformly distributed compressed voxel model, In order to implement the modification of the model, boolean operations are fulfilled among dexel models. These modeling methods were applied to the virtual clay modeling system of automobile with excellent effect.
