User Driven Modeling of Detailed Shapes

我们生活在一个三维世界中，物体的形状或几何形状是它们的主要特征之一。因此，处理真实对象的计算机应用程序（如计算机图形学、工程或医学可视化）需要工具来创建和处理3D形状。直到最近，新的3D内容的创建一直是专家建模师和艺术家的领域。然而，随着计算机扩散到我们生活的各个方面，越来越多的用户对创建新的、个性化的3D内容感兴趣。建筑师的目标是快速传达新的建筑设计，工程师和科学家的目标是生成用于验证的虚拟原型，而普通公众的目标是设计日常物品或个性化他们最喜欢的虚拟世界。在所有这些情况下，用户都希望创建的模型能够反映真实形状的复杂性。 不幸的是，现有的建模方法无法满足这一需求，因为它们需要大量的时间，专业知识和艺术才能来创建复杂，详细的形状。

We live in a three-dimensional world where the shape, or geometry, of objects is one of their major characteristics. Consequently, computer applications that deal with real-life objects, such as computer graphics, engineering, or medical visualization, require tools to create and process 3D shapes. Until recently the creation of new 3D content was the realm of expert modellers and artists. However, with the proliferation of computers into every aspect of our lives, an increasingly diverse set of users is becoming interested in creating new, personalized, 3D content. Architects aim to quickly convey new building designs, engineers and scientists aim to generate virtual prototypes for validation, and members of the general public aim to design everyday objects or personalize their favorite virtual worlds. In all of these cases users expect the created models to reflect the complexity of real-life shapes. Unfortunately existing modeling methodologies fail to address this need, as they require significant time, expertise, and artistic talent to create complex, detailed shapes.
