    • The present invention provides a 3D real-time graphics generator for generating progressive polygon data for rendering 3D graphics that can reduce the amount of data processing by a computer and a storage area for polygon data, facilitates editing of an object by using the progressive polygon data so as to reduce the amount of work of an animator. The progressive polygon data includes information about vertices of a basic polyhedron approximate to a shape of a 3D object and information about detailed vertices of a polyhedron in a level of approximation to the object that is higher than the basic polyhedron, which are determined progressively based on the level of approximation. In the generation of 3D real-time graphics, detailed vertices are sequentially merged into the vertices of the basic polyhedron so as to produce 3D polygon data.
    • 本发明提供了一种用于生成用于渲染3D图形的渐进多边形数据的3D实时图形生成器,其可以减少计算机的数据处理量和用于多边形数据的存储区域,便于使用渐进多边形数据编辑对象 以减少动画师的工作量。 渐进多边形数据包括关于近似于3D对象的形状的基本多面体的顶点的信息,以及关于高于基本多面体的对象的近似度的多面体的详细顶点的信息,其基于 近似水平。 在生成3D实时图形时,将详细的顶点依次合并到基本多面体的顶点,以便产生3D多边形数据。

    • A novel acrylic-functional organopolysiloxane is proposed which has a plural number of silicon-bonded (meth)acryloxyalkyl groups at each molecular chain end along with one or more of silicon-bonded alkoxy groups. The organopolysiloxane exhibits high curability by the irradiation with ultraviolet light or dual curability either by the ultraviolet irradiation or by the dealcoholation condensation reaction in a moisture-containing atmosphere. The acrylic-functional organopolysiloxane is prepared by the dealcoholation condensation reaction between a starting organopolysiloxane having a plural number of silicon-bonded alkoxy groups at each molecular chain end and a (meth)acryloxyalkyl dimethyl silanol compound in the presence of a specific condensation catalyst which is a divalent tin compound such as tin (II) dioctoate promoting the dealcoholation condensation but suppressing the silanol condensation reaction between the moleculaes of the (meth)acryloxyalkyl dimethyl silanol compound.
