Description: This paper presents an interactive technique that
produces static hairstyles by generating individual hair strands
of the desired shape and color, subject to the presence of gravity
and collisions. A variety of hairstyles can be generated by
adjusting the wisp parameters, while the deformation is solved
efficiently, accounting for the effects of gravity and collisions.
Wisps are generated employing statistical approaches. As for
hair deformation, we propose a method which is based on
physical simulation concepts but is simplified to efficiently
solve the static shape of hair. On top of the statistical wisp
model and the deformation solver, a constraint-based styler
is proposed to model artificial features that oppose the natural
flow of hair under gravity and hair elasticity, such as a hairpin.
Our technique spans a wider range of human hairstyles than
previously proposed methods, and the styles generated by this
technique are fairly realistic.-This paper presents an interactive techni que that produces static NAR by generat ing individual hair strands of the desired shap e and color. subject to the presence of gravity and collisio ns.

Description: Some years ago Faurecia used a very simple screw model. In this model the screw holes are filled by a rigid body and the screw
shaft is modeld by a simple spring beam with an unrealistic stiffness. But this model doesn’t represent the behavior of screws in
real test. With this simple model it was not possible to get the peeling effect of the holes. And the deformation of the part and the
screw was unrealistic. Also the forces inside the screw were too high. Platform: |

Description: 我们采用无办法变形质量人体模板的网格从其原来的姿势对点云数据指定不同的姿势。在此方法中，我们首先建立粗模板网格和点云通过压缩的光谱嵌入技术，利用人体四肢之间的对应关系。基于这些对应关系，我们定义使用弹性能量泛函的非刚性配准的目标和应用离散的梯度流，以减少粗控制网格和点云之间的区别。然后可从之后使用均值坐标控制网格的变形变形的模板网格。(We employ a deformable, deformable human body template mesh to specify different poses from its original pose to point cloud data. In this approach, we first build coarse template meshes and point clouds through compressed spectral embedding techniques that exploit the correspondence between human limbs. Based on these correspondences, we define the use of elastic energy functionals for nonrigid registration of targets and apply discrete gradient flows to reduce the difference between coarse control grids and point clouds. Thereafter, the template mesh can be controlled by using mean coordinates to control mesh deformation.) Platform: |
