虽然许多复杂的3D渲染方法可以产生逼真的输出，但3D数据输入仍然是一项繁琐且耗时的任务。提出了一种利用手势创建三维物体的方法。考虑两种类型的3D形状形成任务。一种是从头开始创建一个全新的对象，另一种是通过更改现有对象来创建它。在第一种情况下，3D建模方法的设计和实施，以提供功能，如创建，混合和变形的多个3D形状很容易控制直观的双手手势。隐式超二次函数被应用于建立一个基于手势的3D物体建模器，并扩展了混合和变形。在第二种情况下，提出了一个3D数据管理功能，以共享和重用通过使用上述3D建模器创建的现有形状。所有的3D数据都保持小尺寸，并通过用用户的手描绘部分形状来检索。因此，所提出的方法允许用户一致地处理所有对象建模任务，包括通过自然和直观的手势创建，存储和重用3D对象。一些三维物体和一个微型实体模型示出了所提出的方法的表达能力和实用性。
While many sophisticated 3D rendering methods become available to produce realistic output, 3D data input still is a tedious and time-consuming task. The paper proposes a method for creating 3D objects using hand gestures. Two types of 3D shape forming tasks are considered. One is to create a completely new object from scratch and the other is to make it by changing an existing one. In the first case, a 3D modeling method is designed and implemented to provide functions like creation, blending and deformation of multiple 3D shapes easily controlled by intuitive bimanual gestures. The implicit superquadric functions are applied to building a gesture-based 3D object modeler with extensions of blending and deformations. In the second case, a 3D data management function is proposed to share and reuse existing shapes created by using the 3D modeler mentioned above. All 3D data are kept small in size and retrieved by picturing partial shapes with the user's hands. As a consequence, the proposed method allows users to consistently deal with all object modeling tasks including creation, storage and reuse of 3D objects through natural and intuitive hand gestures. Some 3D objects and a miniature solid model are shown to present the expressive power and usefulness of the proposed method.
