This research handles many types of objects such as water, sands, clouds, clay. We call these material soft objects. We realize realistic rendering of CG images of these soft objects which are deformed according to the environmental changes. The deformation is operated by user-friendly interactive systems so that animations are generated by interactive speed. By establishing these technologies the applications to entertainment filed not only scientific computation filed. The soft objects are categorized as follows; (1) flexible objects such as animal/human bodies. (2) fluid objects such as pigments for oil paining. (3) natural objects such as water, sands, clouds and smoke. The proposed system can handle analysis and dynamics (effective deformation) of these soft objects, and rendering optical effects (reflection/refraction and light scattering) of them. To realize more effective and practical system, we have developed CG system using graphics hardware called GPUs. And we have realized user-friendly operation systems using hepatic devises.

这项研究处理许多类型的对象，如水，沙，云，粘土。我们称这些物质为软物体。实现了这些随环境变化而变形的软物体的CG图像的真实感绘制。变形是由用户友好的交互式系统，使动画生成的交互速度。通过建立这些技术的应用到娱乐领域，而不仅仅是科学计算领域。柔软物体分类如下：（1）柔性物体，如动物/人体。(2)流体物体，如油画颜料。(3)水、沙、云和烟等自然物体。所提出的系统可以处理这些软物体的分析和动态（有效变形），并渲染它们的光学效果（反射/折射和光散射）。为了实现更有效和实用的系统，我们开发了CG系统使用图形硬件称为GPU。并利用肝脏装置实现了人性化的操作系统。
