A new approach for the computation of electric fields is described, based on the response surface methodology(RSM) and geometric feature charge simulation method (GFCSM). And the novel combination of RSM and GFCSM is applied to calculate the electric field of the high voltage SF6 arc quenching chamber in this paper. The electric field distribution with higher calculation precision has been achieved...
A hybrid algorithm for fast drawing ellipse is proposed in this paper. The algorithm is established based on the observation that each quarter ellipse is composed of three regions, and only one kind of primitive appears in one region, such as vertical segment, discrete point pair, and horizontal segment. Among this, the lengths of the vertical and horizontal segments are calculated with double-step...
A run-length algorithm for fast circle drawing with double-step is proposed. In this algorithm, a discrete circle locus can be composed of a series of horizontal line segments and diagonal segments with slope k=-1. The algorithm can directly get the length of those line segments by performing the double-step recurrence using the errors in middle-point method and output those length in one times. The...
A new fast line drawing algorithm that is different from the traditional Bresenham algorithm is presented in this paper. A line is treated as an aggregation of several line segments and the Y coordinate differences of candidate pixel points in every step of traditional algorithm are replaced by the length errors of each segments in this new algorithm. Each operation and judgment can generate a line...
