多线程图形特效，可以预览到多线程播放图片的许多效果，非常方便。-Multi-threaded graphics effects, you can preview images to a multi-threaded playback of many effects, very convenient.

This is a plugin script for Go-ogle"s free 3D design program Sketchup. The free version of Sketchup has limited file export options and many CAM programs will not recognise the native Sketchup (SKP) file format. This plugin allows you to export your Sketchup model as a DXF or STL files readable by most CAM and 3D printer software.Using the pluginAfter copying this file, start Sketchup and you should now have an extra menu option (Export to DXF or STL) in the Sketchup Tools menu.There are five export options:STL  triangles. Use this for Makerbot or Reprap style 3D printersDXF polyface mesh. This will give the most faithful reproduction of your original Sketchup model.DXF polylines: exports the outlines of each face as a polyline, sometimes useful for CAM toolpaths.DXF triangular mesh: breaks all the faces up into trianglesDXF lines.

OTSU方法计算图像二值化的自适应阈值，OTSU 算法可以说是自适应计算单阈值（用来转换灰度图像为二值图像）的简单高效方法。下面的代码最早由 Ryan Dibble提供，此后经过多人Joerg.Schulenburg, R.Z.Liu 等修改，补正。算法对输入的灰度图像的直方图进行分析，将直方图分成两个部分，使得两部分之间的距离最大。划分点就是求得的阈值。都是老外写的，经典哦。-OTSU images calculated value of the two adaptive threshold, OTSU algorithm can be calculated adaptive threshold (for conversion to gray scale images binary images), a simple and efficient manner. The following code from the earliest to provide Ryan Dibble, after a more than Joerg.Schulenburg, R. Z. Liu amend the correction. Algorithm for the importation of gray-scale image histogram analysis of histogram is divided into two parts, Part 2 makes the distance between the largest. Demarcation point out the threshold. Foreigners are written in the classical oh.
