我们提出了一种方法来建立一个三维建模环境，以帮助新的形状概念化。拟议的系统由以下四个功能部分组成：（a）手绘草图界面，其允许用户容易地将他/她的粗略设计想法带入2D几何模型，（B）形状近似模块（SAM），其自动地将草图2D图像转换成3D可变形模型，（c）3D形状探索工具，其通过演化转换的3D模型来生成各种3D模型，以及（d）参数化3D建模器，用于模拟演化的形状。手绘草图接口采用模糊推理技术，灵活地识别用户的手写图像作为七个几何图元之一，通常用于许多CAD工具。SAM将手绘草图自动转换为三维模型后，使用交互式进化计算（IEC）技术对模型进行进化。IEC根据用户的评级自动生成和变形模型，即使是初学者也可以轻松生成有趣的形状。鼓励高级用户和专家使用参数化建模器来完成详细的模型。
We propose an approach to build a 3D modeling environment for aiding new shape conceptualization. The proposed system consists of the following four functional components: (a) a freehand sketch Interface to allow the user to easily bring his/her rough design idea into a 2D geometric model, (b) a shape approximation module (SAM) to automatically convert the sketched 2D image into a 3D deformable model, (c) a 3D shape exploration tool to generate variety of 3D models by evolving the converted 3D model, and (d) a parametric 3D modeler to sophisticate the evolved shapes. The freehand sketch Interface employs a fuzzy Inference technique to flexibly Identify a user's handwritten image as one of seven geometric primitives commonly used in many CAD tools. After the freehand sketch Is automatically converted to a 3D model by the SAM, the model Is evolved by using a technique called Interactive Evolutionary Computation (IEC). IEC automatically generates and deforms the model according to the user's rating and allows even beginners to easily produce interesting shapes. Advanced users and experts are encouraged to use parametric modeler to finish the model with elaboration.
