    • A texture memory for storing color information of a surface of an object and displacement information of the object, wherein the information is prepared in advance; reading means for reading out the color information of the surface of the object and the displacement information of the object necessary for drawing the object from the texture memory in response to receiving a command instructing to draw the object stored in the texture memory according to a size and a position, if necessary, color information and displacement information specified by the command; size modifying means for expanding or reducing and/or modifying the read color information of the surface of the object and the read displacement information of the object by using the color information and the displacement information, and if specified, using the specified displacement information if specified so as to correspond to the size and the displacement specified in the command; color modifying means for modifying the color information processed by the size modifying means based on the specified color information if specified; and hidden surface processing means for performing a hidden surface removal for the drawing surface of the object by using the color information of the surface of the object and the displacement information of the object from the size modifying means or the color modifying means and by the position specified in the command. This enables a rapid measure to be taken against the case of drawing a great number of spheres, pipes or the like.
    • 一种纹理存储器,用于存储对象的表面的颜色信息和对象的位移信息,其中预先准备信息; 读取装置,用于响应于接收到指示根据尺寸绘制存储在纹理存储器中的对象的命令,读出对象的表面的颜色信息和从纹理存储器绘制对象所需的对象的位移信息 以及必要时的位置,由指令指定的颜色信息和位移信息; 尺寸修改装置,用于通过使用颜色信息和位移信息来扩展或减少和/或修改对象的表面的读取的颜色信息和对象的读取的位移信息,如果指定的话,使用指定的位移信息 以对应于命令中指定的大小和位移; 颜色修改装置,用于根据指定的颜色信息修改由尺寸修改装置处理的颜色信息; 以及隐藏表面处理装置,用于通过使用对象的表面的颜色信息和来自尺寸修改装置或颜色修改装置的对象的位移信息以及位置来执行对象的绘制表面的隐藏表面去除 在命令中指定。 这样可以对绘制大量球体,管道等的情况进行快速测量。
