项目摘要

There are many problems which we must solve to apply VR technology to the artistic modeling and to put it to practical use. By this research, I examined about the problems about the construction of the large sculpture working space such as the realizing method of the wide area VR space, the modeling method which can be controlled to the minute structure and the efficient method which outputs the object made in the VR space to the actual space.A movable wide area VR space displaying system which installed on the handcart was developed. The VR world can be seen with being moved through the screen as the peep window. The moving parallax alike the real world can be expressed by the movement of the handcraft.A multi-scale modeler with the layered structure of the modeling space by octree was developed The continuous multi-scale indication and modeling of the objects from surveyed form to minute form can be realized utilizing this modeler. In this modeler, the fineness of the form expression is controlled by a form characteristic value and viewing distance.An automatic Styroform modeling system utilizing the electric heated line was developed as an efficient method which outputs the large object made in the VR space to the actual space. The large objects modeling system which sturdy structure shouldn't be necessary can be realized by this method.

将虚拟现实技术应用到艺术造型中并付诸实践，需要解决很多问题。通过本研究，我探讨了大型雕塑工作空间的构建问题，如广域虚拟现实空间的实现方法，可以控制到微小结构的建模方法，以及将虚拟现实空间中制作的物体输出到实际空间的有效方法。研制了一种安装在手推车上的可移动广域虚拟现实空间显示系统。通过移动屏幕作为窥视窗，可以看到虚拟现实世界。与现实世界相似的运动视差可以通过手工艺品的运动来表达。开发了一种基于八叉树的建模空间分层结构的多尺度建模器，利用该建模器可以实现对物体从测量形状到微小形状的连续多尺度表示和建模。在该建模器中，表单表达的精细程度由表单特征值和观看距离控制。开发了一种利用电热线将虚拟现实空间中制作的大型物体输出到实际空间的有效方法——Styroform自动建模系统。该方法可以实现不需要坚固结构的大型物体建模系统。
