In view of the present virtual hysteroscopy laparoscopic system problems, combined with various processing algorithms, discussed deeply the key techniques about collision detection, deformation computation, and path planning of virtual hysteroscopy laparoscopy surgery simulator system. Subsequently, these three key techniques involved in the virtual hysteroscopy laparoscopy surgery simulator system...
This paper presents an extensible software framework for embedded system modeling on a distributed platform. Actors are concurrent components to specify time-triggered sensor readings, task invocations, actuator updates, and pattern switches independent of any given platform. Composite actor can be arbitrarily nested and framework consists of a formal semantics by separating platform-independent concerns...
In this paper, a new method for real-time rendering of three-dimensional terrain is proposed. The method combines together several methods such as block data, view-dependent multi-resolution LOD, view frustum culling etc. It exploits a new method to measure the terrain curvature. The new method uses multiple-approach to simplify terrain model and reduce the cost of memory, which can improve efficient...
