For CAD/CAM/CAE practical applications, one of the difficult problem is to deal with huge amount of information input requirement. Particularly today's two dimensional input method is not satisfactory for inputting necessary information for constructing three dimensional shape information with aeshetic features. To solve this difficulty, a new input method is developed by use of existing objects or prototype products.1. Three Dimensional Interface :Direct manipulation of computer models by use of three dimensional pointing devices has been developed. This method can be used effectively for fine elaboration of aesthetic shapes.2. Model Input Methid :A method has been investigated for capturing three dimensional shape information by mesuring real objects, and for reconstruction of measured shapes in computer, and further elaboration with human interaction.3. Rapid Prototyping Information Generation :Automatic data generation methods have been developed for creating objects by use of rapid prototyping devices, such as laser lithographic machines. New algorithms have been considered for avoiding shaping errors by analzing layr directions and laser scanning modes.In summary, methods for rapidly crating high-quality computer internal by interaction with real objects have been developed, and their effectiveness have been verified by an experimental system.

对于CAD/CAM/CAE实际应用，一个困难的问题之一是处理大量信息输入要求。特别是在输入具有厌食特征的三维形状信息的必要信息时，当今的二维输入方法并不令人满意。为了解决这个困难，通过使用现有对象或原型产品来开发一种新的输入方法。1。三维接口：已经开发了使用三维指向设备对计算机模型的直接操纵。该方法可有效地用于精细阐述美学形状2。模型输入METH：已经研究了一种方法，用于通过调查真实对象，重建计算机中测量的形状，并与人类相互作用进行进一步阐述。3。快速原型信息生成：已经开发了自动数据生成方法，用于通过使用快速原型设备（例如激光光刻机器）来创建对象。已经考虑了通过对Layr方向和激光扫描模式进行肛门算法来避免造成误差的新算法。总而言之，通过与实际物体相互作用来快速板条高质量计算机内部的方法，并通过实验系统验证了它们的有效性。
