City 3D Graphic and Image Mixed Large-scale Scene Huge Data Urban Building
2018/6/5
Urban 3D model data is huge and unstructured, LOD and Out-of-core algorithm are usually used to reduce the amount of data that drawn in each frame to improve the rendering efficiency. When the scene i...
SIMULATION OF THE «COSMONAUT-ROBOT» SYSTEM INTERACTION ON THE LUNAR SURFACE BASED ON METHODS OF MACHINE VISION AND COMPUTER GRAPHICS
Lunar Exploration Extravehicular Activity (EVA) Human-Robot Interaction (HRI) Mobile Robot Control "Follow Me" Mode Gesture Interface Object Tracking Gesture Recognition Motion Capture
2017/6/19
Extravehicular activity (EVA) on the lunar surface, necessary for the future exploration of the Moon, involves extensive use of robots. One of the factors of safe EVA is a proper interaction between c...
Cofactorization on Graphics Processing Units
Cofactorization Graphics Processing Unit Number Field Sieve
2016/1/9
We show how the cofactorization step, a compute-intensive part of the relation
collection phase of the number field sieve (NFS), can be farmed out to a graphics processing
unit. Our implementation o...
