在交互式计算机游戏和3D形状设计中，添加交互式触觉约束感觉非常重要。通常在对象的顶点上设置约束以驱动变形。如何在交互设计中模拟动态力约束仍然是一个具有挑战性的任务。本文提出了一种基于交互式元球的触觉约束建模方法，该方法将触觉约束工具吸引到目标位置，然后控制约束区域内的触觉变形。交互作用力反馈帮助设计者准确地变形目标区域，并将细节按照他们的意图精细地雕刻在物体上。我们的工作是研究如何使用交互式变形球将触觉应用到这种受约束的变形中，从而使用户在变形交互过程中能够真实地感受和控制软触摸对象。实验结果表明，通过我们开发的交互界面，用户可以直观地模拟触觉操作过程中的动态触觉。版权所有©2010 John Wiley&Sons，Ltd.
Adding interactive haptic‐constraint sensations is important in interactive computer gaming and 3D shape design. Usually constraints are set on vertices of the object to drive the deformation. How to simulate dynamic force constraints in interactive design is still a challenging task. In this paper, we propose a novel haptic‐constraint modeling method based on interactive metaballs, during which the haptic‐constraint tools are attracted to the target location and then control the touch‐enabled deformation within the constrained areas. The interactive force feedbacks facilitate designers to accurately deform the target regions and fine carve the details as their intention on the objects. Our work studies how to apply touch sensation in such constrained deformations using interactive metaballs, thus users can truly feel and control the soft‐touch objects during the deforming interactions. Experimental results show that the dynamic sense of touch during the haptic manipulation is intuitively simulated to users, via the interacting interface we have developed.
