Animation cartography—intrinsic reconstruction of shape and motion
Art Tevs, Alexander Berner, Michael Wand, Ivo Ihrke, Martin Bokeloh, Jens Kerber, Hans-Peter Seidel
Article No.: 12
DOI: 10.1145/2159516.2159517

In this article, we consider the problem of animation reconstruction, that is, the reconstruction of shape and motion of a deformable object from dynamic 3D scanner data, without using user-provided template models. Unlike previous work that...

Fast high-resolution appearance editing using superimposed projections
Daniel G. Aliaga, Yu Hong Yeung, Alvin Law, Behzad Sajadi, Aditi Majumder
Article No.: 13
DOI: 10.1145/2159516.2159518

We present a system that superimposes multiple projections onto an object of arbitrary shape and color to produce high-resolution appearance changes. Our system produces appearances at an improved resolution compared to prior works and can change...

Spacetime expression cloning for blendshapes
Yeongho Seol, J.P. Lewis, Jaewoo Seo, Byungkuk Choi, Ken Anjyo, Junyong Noh
Article No.: 14
DOI: 10.1145/2159516.2159519

The goal of a practical facial animation retargeting system is to reproduce the character of a source animation on a target face while providing room for additional creative control by the animator. This article presents a novel spacetime facial...

Resolution enhancement by vibrating displays
Floraine Berthouzoz, Raanan Fattal
Article No.: 15
DOI: 10.1145/2159516.2159521

We present a method that makes use of the retinal integration time in the human visual system for increasing the resolution of displays. Given an input image with a resolution higher than the display resolution, we compute several images that...

MultiFLIP for energetic two-phase fluid simulation
Landon Boyd, Robert Bridson
Article No.: 16
DOI: 10.1145/2159516.2159522

Physically-based liquid animations often ignore the influence of air, giving up interesting behavior. We present a new method which treats both air and liquid as incompressible, more accurately reproducing the reality observed at scales relevant...

Bilinear spatiotemporal basis models
Ijaz Akhter, Tomas Simon, Sohaib Khan, Iain Matthews, Yaser Sheikh
Article No.: 17
DOI: 10.1145/2159516.2159523

A variety of dynamic objects, such as faces, bodies, and cloth, are represented in computer graphics as a collection of moving spatial landmarks. Spatiotemporal data is inherent in a number of graphics applications including animation, simulation,...
