A vertical profile of the 3D wellbore trajectory is generally.The challenge is how to draw the actual wellbore trajectory on the vertical profile of planned well trajectory.A planned 3D well path profile is depicted using vertical depth and projection length,however,the actual wellpath profile is supposed to be drawn using vertical depth and apparent projection length.

三维井眼一般都绘制垂直剖面图，其难点就是怎样在设计井眼轨道的垂直剖面图上描绘实钻井眼轨迹的剖面线，由于三维井眼设计剖面图是用垂深与投影长度绘制，其实钻井眼轨迹剖面图应该是用垂深和视投影长度绘制。

First,image structure vector field is derived from source luminance orthonormal vector sets. Andusing neighbor vectors to improve the weak gradient fields produces the structure vectorfield that is needed by LIC rendering. Then, LIC convolution step-length is adjustedaccording to local curvature in the structure vector field. LIC convolution length iscalculated according to the local statistical characteristics of the texture image. Finally, thealgorithm transfers the reference image\'s color characteristics to the rendering result tomake it full of rich color like oil paintings.

该算法通过计算源图像亮度分量的切矢量产生图像的结构矢量场，并对弱矢量区域进行邻域填充处理，获得LIC绘制所需的结构矢量场；然后，根据结构矢量场的局部曲率特征调整LIC的积分步长，并根据纹理参考图像的局部统计特征，自适应地改变LIC的积分长度；最后，将颜色传输算法引入LIC绘制结果，对绘制效果颜色进行渲染。

在这篇教程中图的大小是1024×1024.STEP_SIZE是我们用来绘制地形的正方体的大小，减小步长，地形图就会变得更加平滑。有一点很重要，步长越小你的程序所做的工作就将越多，特别是在使用大的高度图时。HEIGHT_RATIO用来缩放地形的Y轴的值，较小的HEIGHT_RATIO可以用来绘制较平的山，较大的HEIGHT_RATIO用来绘制较高的山。在下面的代码中，你会看到变量bRender。如果bRender的值为真，我们就填充模式绘制多边形，如果它的值为假，那么我们就用线框模式绘制地形。

根据数据源的不同，非真实感绘制技术可分为两类：基于三维观察空间的绘制-绘制3D场景和基于图像空间的绘制-绘制2D图像。

From the development and present status of automatic mapping contour maps, we know that the technology of automatic mapping contour maps which contains faults especially cross bedded faults was developed slowly, which are part of contour maps. In the process of our factual work, the phenomenon of half-handcraft mapping contour maps containing singular and cross-bedded faults is ubiquitous.

从等高线图自动绘制的发展历史及现状可以看出，断层等高线图是平面等高线图的一部分，含断层等高线图的自动绘制，尤其是带交叉断层等高线图的自动绘制技术发展缓慢，半手工绘制单一断层和交叉断层的等高线图的现象还普遍存在。
