    摘要： The invention provides techniques for wrapping a two-dimensional texture conformally onto a surface of a three dimensional virtual object within an arbitrarily-shaped, user-defined region. The techniques provide minimum distortion and allow interactive manipulation of the mapped texture. The techniques feature an energy minimization scheme in which distances between points on the surface of the three-dimensional virtual object serve as set lengths for springs connecting points of a planar mesh. The planar mesh is adjusted to minimize spring energy, and then used to define a patch upon which a two-dimensional texture is superimposed. Points on the surface of the virtual object are then mapped to corresponding points of the texture. The invention also features a haptic/graphical user interface element that allows a user to interactively and intuitively adjust texture mapped within the arbitrary, user-defined region.

    摘要翻译： 本发明提供了将二维纹理保形地包裹在任意形状的用户定义区域内的三维虚拟对象的表面上的技术。 这些技术提供最小的失真并允许映射纹理的交互式操纵。 该技术的特征在于能量最小化方案，其中三维虚拟对象的表面上的点之间的距离用作连接平面网格的点的弹簧的设定长度。 调整平面网格以最小化弹簧能量，然后用于限定叠加二维纹理的贴片。 然后将虚拟对象表面上的点映射到纹理的相应点。 本发明还具有触觉/图形用户界面元素，其允许用户交互地和直观地调整在任意的用户定义区域内映射的纹理。

    摘要： An input device for an interactive computer simulation or game is disclosed which includes a structure having at least two degrees-of-freedom which is moveable by a digit of a user to transmit input signal to a computer. At least one actuator connected to the moveable structure receives inputs from a computer and applies forces in the at least two degrees-of-freedom to the movable structure and thereby to the digit of the user. The actuator may include an electric motor and any of a variety of force transmission schemes including direct, cable, gear or belt drives. The applied forces are typically based on internal programming within the computer, events occurring in the simulation and movements of and forces applied to the movable structure by the operator. The input device of the invention thereby provides continuous interaction among motion of and forces applied by the movable structure, the events in the simulation and forces applied to and applied by the movable structure to enhance user enjoyment and performance.
