Proceedings of the 17th annual conference on computer graphics and interactive techniques
作者: David Baraff Program of Computer Graphics Cornell University Ithaca NY
A formulation for the contact forces between curved surfaces in resting (non-colliding) contact is presented. In contrast to previous formulations, constraints on the allowable tangential movement between contacting s...

A NUMERICAL PROCEDURE FOR SIMULATION OF HYDRAULICALLY-DRIVEN FRACTURE PROPAGATION IN POROELASTIC MEDIA
收藏 引用
INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS 1990年 第1期14卷 27-+页
作者: BOONE, TJ INGRAFFEA, AR Program of Computer Graphics and School of Civil and Environmental Engineering Cornell University Ithaca NY 14853-3501 U.S.A.
A procedure for numerical approximation to two-dimensional, hydraulically-driven fracture propagation in a poroelastic material is described. The method uses a partitioned solution procedurè to solve a finite ele... 详细信息

Proceedings of the 17th annual conference on computer graphics and interactive techniques
作者: Jed Lengyel Mark Reichert Bruce R. Donald Donald P. Greenberg Graduate Student Program of Computer Graphics Cornell University Ithaca N.Y. Assistant Professor and Director Computer Science Robotics Laboratory Department of Computer Science 4130 Upson HalI Cornell University Ithaca N.Y. Director Program of Computer Graphics Jacob Gould Shurman Professor of Computer Graphics Cornell University Ithaca N.Y.
We present a real-time robot motion planner that is fast and complete to a resolution. The technique is guaranteed to find a path if one exists at the resolution, and all paths returned are safe. The planner can handl...

1990 Symposium on Interactive 3D graphics, I3D 1990
作者: Puech, Claude Sillion, François Vedel, Christophe Laboratoire d'Informatique Ecole Normale Supérieure 45 rue d'Ulm Paris75005 France Program of Computer Graphics Cornell University 120 Rand Hall IthacaNY14853 United States LIBNS URA 1327 CNRS France LIENS France
We describe the main algorithms used in an interactive lighting simulation program based on a twopass extension of the radiosity method. The system allows interactive walk-through as other systems based on radiosity c... 详细信息

16th Annual Conference on computer graphics and Interactive Techniques, SIGGRAPH 1989
作者: Stettner, Adam Greenberg, Donald P. Program of Computer Graphics Cornell University IthacaNY14853 United States
computer simulations can be used to generate the spatial and temporal data describing the acoustical behavior of performance halls, but typically the analytical results are difficult to assimilate and compare. By usin... 详细信息

computerS & STRUCTURES 1989年 第5期33卷 1183-1190页
作者: SALMON, DC ABEL, JF Depart ment of Architecture Cornell University Ithaca NY 14853 U.S.A. School of Civil and Environmental Engineering Program of Computer Graphics Cornell University Ithaca NY 14853 U.S.A.
The Q9 membrane finite element is unable to experience arbitrary change of uniaxial curvature without the occurence of artificial membrane stains. The error which accumulates due to this inability can be significant w... 详细信息

15th International Conference on computer graphics and Interactive Techniques, SIGGRAPH 1988
作者: Cohen, Michael F. Chen, Shenchang Eric Wallace, John R. Greenberg, Donald P. Program of Computer Graphics Cornell University United States
A reformulated radiosity algorithm is presented that produces initial images in time linear to the number of patches. The enormous memory costs of the radiosity algorithm are also eliminated by computing form-factors ... 详细信息
