离散光滑T-曲面的等距变形

Isometric Deformations of Discrete and Smooth T-surfaces

Ivan Izmestiev, Arvin Rasoulzadeh, Jonas Tervooren

摘要:

四边形曲面是具有四边形面和正方形网格的组合的多面体曲面。一般四边形曲面是刚性的。T面体是Graf和Sauer在1931年提出的一类柔性四边形曲面。T面体的特别例子是著名的三浦折叠,离散的旋转表面和离散的成型表面。我们提供了一个显式参数化的等距变形的T-面体。T面体有一个光滑的类似物,T面。对于这些,我们提供了一个合成和分析的描述,都类似于相应的描述的T-面体。我们还参数化的等距变形的T-曲面,并讨论其变形范围。

英文摘要:

Quad-surfaces are polyhedral surfaces with quadrilateral faces and the combinatorics of the square grid. A generic quad-surface is rigid. T-hedra is a class of flexible quad-surfaces introduced by Graf and Sauer in 1931. Particular examples of T-hedra are the celebrated Miura fold, discrete surfaces of revolution, and discrete molding surfaces. We provide an explicit parametrization of the isometric deformation of a T-hedron. T-hedra have a smooth analog, T-surfaces. For these we provide a synthetic and an analytic description, both similar to the corresponding descriptions of T-hedra. We also parametrize the isometric deformations of T-surfaces and discuss their deformability range.
