In this paper, we propose an efficient terrain meshing method based on discrete point cloud, which is based on the existing meshing method of 3D reconstruction. Our meshing method uses the DTM (Delaunay Triangle Mesh) as a criterion to establish vertex constraints and evaluation functions. We start from a seed triangle and use the growing method to extend the outer-edge of each triangle until all...
Scene space organizational structure and visibility culling plays a crucial role in the quality and efficiency of subsequent rendering. To improve the real-time rendering of indoor and outdoor objects and enhance the organization efficiency of scenes, we propose an optimized scene management structure for fast visibility culling. We organize the scene into an adaptive binary tree (ABT) structure to...
Scene management technology is one of the key technologies of virtual reality and visualization. In this paper, we propose a new method based on adaptive binary tree (ABT) and scene graph, which is used to improve the real-time rendering of indoor and outdoor objects and enhance the organization efficiency of scenes structure. The generation algorithm of adaptive binary tree, the scoring standard...
LCLC converter is an LLC-based, four-element resonant topology, which has been proved to achieve high voltage gain and high efficiency. Such trait makes LCLC converter specifically suitable for wide-input-voltage-range DC/DC applications. Currently, LCLC converter lacks a design method targeting at optimal efficiency over a wide input voltage range. In fact, due to the complexity, efficiency itself...
Dynamic voltage Scaling (DVS) has been widely studied as an innovative technology in reducing the real-time embedded devices. An efficient performance of DVS algorithm largely depends on how to acquire more slack times to scale voltage down. In this paper, we present a more effective power management algorithm to reclaim online slack time from both higher-priority and lower-priority tasks. Based on...
This paper proposes a new approach to optimally design LLC converters. The core of the proposed approach is an accurate algorithm that can find all the possible designs satisfying the peak gain requirement. Designers can conveniently evaluate several design results and find the optimal one for their respective applications. Part I of this paper proposes the accurate design algorithm, which is developed...
