This paper introduces an automatically reasoning system for inferring curved-surface solids from inconsistent three views. Our system is based on a so-called knowledge-based method that imitates human reasoning process in inferring curved-surface solids from inconsistent views. Initially, curved-surface primitives are recognized and extracted one by one according to their possibility value computed from all the given three views. Next, those data only relative to curved-surface primitives are removed from three views, and then polyhedrons will be constructed. The final solid is formed by assembling all those generated curved-surface primitives and polyhedrons. Our system has been implemented in C and OpenGL on Windows NT. The constructed solid can be observed at free angles through rotating it with keyboard. Many examples are tested and the experimental results show that our system is very robust, and can accurately and effectively construct a suitable curved-surface solid from inconsistent three views.
