besides, the paper presents a simple but useful method of isoline labeling, azimuth angle judgement algorithm 在等值线标注部分,采用简单实用的向量判断法,确定标注的位置。
in the post-process, uses the microsoft medias technical to design cartoon display mode, it raises cartoon speed and saves disc space, it can produce majority prevailing medias form . in interpolation, introduced dsi method, which improve the interpolation method of isoline, raise algorithm speed and efficiency, satisfy the real-time quality request . on the basis of scanning line algorithm, use opengl smooth interpolate method to improve the implementati 在后处理过程中,引进了dsi插值方法,改进了以往等值线插值,提高了算法速度和效率,满足了实时性要求,在扫描线算法的基础上,引进了opm沁l插值方法,改进了云图实现方法,提高了图形显示精度,在动画格式上,我们可以根掘自己需要实现不同精度的不同压缩格式动画文件,提高了后处理显示应用场合,改变了以往动画格式单一的形式。
