    • A system and method are disclosed for manipulating objects within a virtual environment using a software widget. The software widget includes one or more controls for performing surface constrained manipulation operations. A graphical representation of the software widget is superimposed over the object and enables a user to use simple mouse operations to perform the various manipulation operations. The position operation determines an intersection point between the mouse cursor and a surface of a different object and moves the object to the intersection point. The scale operation adjusts the size of the object. The rotate operation adjusts the rotation of the object around a normal vector on the surface of the different object. The twist operation deforms the object along a local z-axis. The orientation operation adjusts the orientation of the object with respect to the normal vector.
    • 公开了一种使用软件小部件来操纵虚拟环境内的对象的系统和方法。 软件小组件包括用于执行表面约束操纵操作的一个或多个控件。 软件小部件的图形表示叠加在对象上,并使用户能够使用简单的鼠标操作来执行各种操作操作。 位置操作确定鼠标光标和不同对象的表面之间的交点,并将对象移动到交点。 缩放操作调整对象的大小。 旋转操作调整对象围绕不同对象表面上的法向量的旋转。 扭转操作使物体沿局部z轴变形。 方向操作相对于法向量调整对象的方向。

    • A system and method are disclosed for implementing a resolution-adaptive mesh smoothing brush. The resolution-adaptive mesh smoothing brush computes updated positions of vertices of a 3D mesh based on vertex density of the polygons defining the 3D mesh. The resolution-adaptive mesh smoothing brush effectively controls the “rate” of smoothing based on the local mesh density at each vertex. Therefore, areas of the 3D mesh with varying vertex density are smoothed. For example, elevated bumps or dimples on a sphere may be smoothed to lay on the surface of the sphere while the sphere shape is retained.
    • 公开了一种用于实现分辨率自适应网格平滑刷的系统和方法。 分辨率自适应网格平滑刷基于基于定义3D网格的多边形的顶点密度计算3D网格的顶点的更新位置。 分辨率自适应网格平滑刷基于每个顶点的局部网格密度有效地控制平滑的“速率”。 因此,具有不同顶点密度的3D网格的区域被平滑化。 例如,球体上的凸起或凹坑可以被平滑以放置在球体的表面上,同时保持球形。
