3D打印开源库--CuraEngine

这是一个3D打印切片和路经规划库.

The slicing process follows the following global steps:

Load 3D model
Analize and fix 3D model
Slice 3D model into 2D layers
Build LayerParts from sliced layers
Generate Insets
Generate up/down skins areas
Generate sparse infill areas
Generate GCode for each layer 我主要用到了它的二维规划子函数.
- infill.cpp 用来完成内部填充
- pathOrderOptimizer.cpp 内轮廓和外轮廓的规划
- intpoint.h 以上两个文件需要的数据结构
- clipper.cpp 对上面的数据结构体进行操作的库.可以区分内外边框

个人认为这是一个很好的路径规划和3D切片参考库.

generateLineInfill(PGtmp,m_PG,1000,m_ResolutionY*100,m_ResolutionY,45,PGtmp);
// 判断内外圈
bool mback = ClipperLib::Orientation(PGtmp[0]);

//hierarchy  next and previous, first child contour and the parent contour
cv::findContours(phrone ,contours ,hierarchy, CV_RETR_CCOMP,CV_CHAIN_APPROX_SIMPLE );
cv::Mat dst = cv::Mat::zeros(phrone.rows,phrone.cols,CV_8UC3);
if (contours.size()==0)
{
    continue;
}
// 遍历外框排序
PathOptimizer pathOptimize(ClipperLib::IntPoint(0,0));// 增加入口点
ClipperLib::Polygons plogs;
vector<int> orderid;
for( int idx = 0; idx >= 0; idx = hierarchy[idx][0] )//外框遍历
{
    if (contours[idx].size() < 3)
    {
        continue;
    }
    ClipperLib::Polygon plog;
    for (int i=0; i<contours[idx].size(); i++)
    {
        plog.push_back(ClipperLib::IntPoint(contours[idx][i].x,contours[idx][i].y));
    }
    plogs.push_back(plog);
    orderid.push_back(idx);
}
pathOptimize.addPolygons(plogs);
pathOptimize.optimize();
