SIGGRAPH Previews 2012 Technical Papers
3D scans of real fabrics to design new 3D fabrics for rendering. The fabrics are rendered in a physically based way, which allows textile designers to predict how a given weave pattern would look if it were fabricated, resulting in highly realistic results for textile design, ecommerce, entertainment, and apparel visualization.
Precomputed Acceleration Noise for Improved Rigid-Body Sound
Authors: Jeffrey N. Chadwick, Changxi Zheng, and Doug L. James, Cornell University
Colliding objects produce impact sounds, usually described by modal synthesis. This paper introduces the effect of acceleration in this model, thus allowing for rendering more realistic, crisper collision sounds, or making a sound audible when the modal component only would be inaudible by humans.
Design of Self-Supporting Surfaces
Authors: Etienne Vouga, Columbia University/King Abdullah University of Science and Technology; Mathias Höbinger, Evolute/TU Wien, Johannes Wallner, TU Graz/TU Wien; Helmut Pottmann, King Abdullah University of Science and Technology
Finding architectural shapes that are self-supporting is a major challenge in masonry. Discrete differential geometry allows the authors to propose a non-linear optimization process approximating a given surface by a self-supporting one. They also produce a quad mesh with planar faces guiding steel/glass constructions.
Eulerian Video Magnification for Revealing Subtle Changes in the World
Authors: Hao-Yu Wu, Michael Rubinstein, Massachusetts Institute of Technology, CSAIL; Eugene Shih, Quanta Research Cambridge, Inc.; Frédo Durand, William Freeman, Massachusetts Institute of Technology, CSAIL
Using an Eulerian formulation and signal-processing principles, the authors amplify subtle changes in videos that could not be perceived otherwise.
CrossShade: Shading Concept Sketches Using Cross-Section Curves
Authors: Cloud Shao, University of Toronto; Adrien Bousseau, REVES - INRIA Sophia Antipolis; Alla Sheffer, The University of British Columbia; Karan Singh, University of Toronto
Cross-section curves are often used by artists to depict man-made objects. This paper exploits perceptual principles to derive a framework for shading these sketches, reconstructing appropriate normals and rendering them in a 3D-like fashion.
