Elastic
Textures for Additive Fabrication
We introduce
elastic textures: a set of parametric, tileable,
printable, cubic patterns achieving a broad
range of elastic material properties: the
softest pattern is over a thousand times softer
than the stiffest, and the Poisson ratios range
from below zero to nearly 0.5...

Robust
Field-aligned Global Parametrization
| We present a
robust method for computing locally bijective
global parametrization aligned with a given
cross-field. The singularities of the
parametrization in general agree with
singularities of the field, except in a small
number of cases when several additional cones
need to be added in a controlled way. |

Animation-Aware
Quadrangulation
| Geometric
meshes that model animated characters must be

animation. We analyze an input sequence of

we automatically produce a quadrangular mesh
that fits well the input animation |

Global

| We present a

Simple
Quad domains for Field Aligned..
| We present a
method for the global parametrization of meshes
that preserves alignment to a cross field in
input while obtaining a parametric domain made
of few coarse axis-aligned rectangular
patches,which form an abstract base complex
without T-junctions. |

Its control mesh is coarse and adaptive, and it
is obtained by simplifying an initial mesh at
high resolution. |

T-meshes
| T-meshes
offer more flexibility for reduction of the
number of patches and vertices in a base
domain while maintaining alignment with
geometric features. At the same time, T-meshes
retain many desirable features of
quadrangulations, allowing construction of
high-order representations, easy packing of
regularly sampled geometric data into
textures, as well as supporting different
types of discretizations for physical
simulation. |

In this survey, we illustrate the
different algorithms proposed in literature to

textures are an efficient instrument to
compactly represent both the external and
internal appearance of 3D objects, providing
practical advantages with respect to classical
2D texturing.

| We introduce
a new appearance-modeling paradigm for
synthesizing the internal structure of a 3D

of a real object. When the internal surfaces
of the 3D model are revealed as it is cut,
carved, or simply clipped, we synthesize their
texture from the input photographs. |
