OVERVIEW OF THE EFFECTS OF THE SPACE ENVIRONMENT Outgassing in near vacuum Atmospheric drag Chemical reactions Plasma-induced charging Radiation damage of microcircuits, solar arrays, and sensors single event upsets in digital devices Hyper-velocity impacts

Sampling Sampling provides a discrete-time representation of a continuous waveform Sample points are real-valued numbers In order to transmit over a digital system we must first convert into discrete valued numbers

第3章基本图形生成算法 3.1生成直线的常用算法均假定所画直线的斜率k∈[0,1]。 3.1.1DDA画线算法 DDA (Digital Differential Analyzer )画线算法也称数值微分法,是一种增量 算法。它的算法实质是用数值方法解微分 方程,通过同时对x和y各增加一个小增量 ,计算下一步的x、y值
