我们提出了一种新的技术，既灵活又有效，用于交互式重新划分不规则几何图形。首先，用参数空间中的一系列二维映射代替原始的(任意亏格)网格。使用这些地图，我们的算法就能够利用现有的信号处理和半色调工具，提供实时交互和复杂的控制。用户可以轻松地组合这些贴图以创建控制贴图-控制曲面面片上的采样密度的贴图。然后以交互速率对该地图进行采样，从而允许用户轻松地设计定制的重新采样。一旦采样完成，我们将执行Delaunay三角剖分和快速优化来完善最终的网格。因此，我们的重新网格化技术非常通用和通用，能够产生具有各种属性的任意复杂的网格，包括：一致性、规则性、半规则性、曲率敏感的重采样和特征保留。我们提供了对采样分布的高级别控制，允许用户根据他们的要求交互地定制设计网格，从而提高他们创建各种网格的生产率。
We present a novel technique, both fle xible and efficient, for interactive remeshing, of irregular geometry. First, the original (arbitrary genus) mesh is substituted by a series of 2D maps in parameter space. Using these maps, our algorithm is then able to take advantage of established signal processing and halftoning tools that offer real-time interaction and intricate control. The User can easily combine these maps to create a control map - a map which controls the sampling density over the Surface patch. This map is then sampled at interactive rates allowing the user to easily design a tailored resampling. Once this sampling is complete, a Delaunay triangulation and fast optimization are performed to perfect the final mesh.As a result, our remeshing technique is extremely versatile and general, being able to produce arbitrarily complex meshes with a variety of properties including: uniformity, regularity, semiregularity, curvature sensitive resampling, and feature preservation. We provide a high level of control over the sampling distribution allowing the user to interactively custom design the mesh based on their requirements thereby increasing their productivity in creating a wide variety of meshes.
