    • An image generating apparatus displays a highly expressive display of a polyhedron representing an object made from a pliable material using only a very small computational load. The image generating device displays images of polyhedrons located in a virtual space and includes a mass point setting circuit setting mass points across an entire surface of a polyhedron, an influential force setting circuit setting influential forces acting on the mass points, a mass point position calculating circuit calculating the positional coordinates of the mass points on the basis of the influential forces set by the influential force setting circuit; and a figure generating circuit generating a figure of the polyhedron on the basis of the positional coordinates for the mass points calculated by said mass point position calculating circuit. Since the positional coordinates of mass points are calculated on the basis of influential forces which simulate the forces acting on a real planar object, it is possible to generate a figure of a polyhedron which moves like a real, pliable planar object.
    • 图像生成装置仅使用非常小的计算负荷来显示表示由柔性材料制成的物体的多面体的高度表现性显示。 图像生成装置显示位于虚拟空间中的多面体的图像,并且包括设置多面体整个表面上的质点的质点设置电路,设置作用在质点上的影响力的影响力设定电路,质点位置计算 基于由影响力设定电路设定的影响力来计算质点的位置坐标; 以及图形生成电路,其基于由所述质点位置计算电路计算的质点的位置坐标,生成多面体的图形。 由于质量点的位置坐标是基于模拟作用在真实平面物体上的力的影响力来计算的,所以可以生成像真实的,柔韧的平面物体一样移动的多面体的图形。
