Generating folding sequences from crease patterns of flat-foldable origami
Found in: ACM SIGGRAPH 2013 Posters (SIGGRAPH '13)
By Hugo A. Akitaya, Jun Mitani, Yoshihiro Kanamori, Yukio Fukui
Issue Date:July 2013
pp. 1-1
The most common form to convey origami is through origami diagrams, which are step-by-step sequences, composed of figures that represent the state of the folded paper, in combination with lines and arrows indicating the position of the folds and the moveme...
     
Fast hair collision handling using slice planes
Found in: Proceedings of the ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games (I3D '13)
By Yoshihiro Kanamori
Issue Date:March 2013
pp. 185-185
In hair simulation, hair collision handling plays an important role to make hair look realistic; hair collision maintains the volume of hair. Without hair collision, hair would appear unnaturally flat.
     
Region matching with proxy ellipses for coloring hand-drawn animations
Found in: SIGGRAPH Asia 2012 Technical Briefs (SA '12)
By Yoshihiro Kanamori
Issue Date:November 2012
pp. 1-4
Hand-drawn animations are fascinating due to their expressiveness. In the production pipeline, manual coloring of line drawings is tedious and labor-intensive. We propose a method for accelerating the coloring step by matching corresponding regions in succ...
     
Local optimization of distortions in wide-angle images using moving least-squares
Found in: Proceedings of the 27th Spring Conference on Computer Graphics (SCCG '11)
By Yoshihiro Kanamori
Issue Date:April 2011
pp. 51-56
We present a fast algorithm for reducing the undesired distortions (e.g., bending of straight lines) that often appear in wide-angle images especially taken with fisheye lenses. Our method allows the user to intuitively specify curves to be straightened by...
     
Elastic rod simulation by chain shape matching with twisting effect
Found in: ACM SIGGRAPH ASIA 2010 Sketches (SA '10)
By Tomoyuki Nishita, Witawat Rungjiratananon, Yoshihiro Kanamori
Issue Date:December 2010
pp. 1-2
One-dimensional deformable objects or elastic rods are widely used to represent threads, hair strands and elastic ropes in computer graphics. Such an object has the bending, stretching and twisting behaviors which are difficult to handle. To simulate defor...
     
Eccentric radial basis functions and the applications
Found in: ACM SIGGRAPH 2008 talks (SIGGRAPH '08)
By Eiji Takaoki, Tomoyuki Nishita, Yoshihiro Kanamori
Issue Date:August 2008
pp. 110-110
We integrate coded apertures into off-the-shelf projectors to increase their focal depth. The regional defocus of the projection on the surface is measured automatically. The projected images are then deconvolved with locally scaled aperture codes. This le...
     
Eccentric radial basis functions and its applications
Found in: ACM SIGGRAPH 2008 posters (SIGGRAPH '08)
By Eiji Takaoki, Tomoyuki Nishita, Yoshihiro Kanamori
Issue Date:August 2008
pp. 110-110
By pointing your index and middle fingers downward and make strides with them, you have what looks like a walking hand. Whadget is an interactive animation which uses a system that distinguishes various personified gesture motions of a hand such as walking...
