【摘要】 针对雕塑作品构思和设计阶段的需求,开发了一个基于Java3D中索引曲面造型方法的虚拟雕塑系统.可以用简单的交互操作,模仿雕塑的手工过程,修改形体几何信息.通过对变形结果的展现、比较和修改,优化设计效果,给出修改形体拓扑结构的实现方法,丰富了虚拟雕塑操作的种类,提高了模型的变形能力.该系统操作方便,对用户使用的技术水平要求低,与专业雕塑人员习惯操作比较吻合,并可推广到工艺品、玩具、景观的方案设计等多个领域.更多还原

【Abstract】 Aiming at the requirement in the design of sculpture production,a virtual sculpture system was developed based on index-surfaces in Java3D.Using simple alternant operation,the manual process of sculpture can be imitated and the geometrical information of body can be modified.Through exhibiting,comparing and modifying the transformative effect as well as optimizing the design effect,an implement method of modifying topological configuration of body was put forward.The proposed method can enrich the variety of virtual sculpture operation and improve the transformative capability of the model.The system has such advantages as easy operation and low technical level requirement for user,and is consistent with the customary operation of professional sculpture persons.The system can be extended to many fields including the scheme design of technologic production,toy and scene.更多还原
