We had used vtkImplicitPolyDataDistance to calculate the distance from a point to the target points set in the post Calculate Distance From A Point To PolyData In VTK. We will try a new way using KD-Tree to find the closest point to the test point. The following example puts a Read more…

Get field value by std::get from container We can use std::get to fetch field value from container object. It can help us to avoid use iteractor to access first or second element. #include <iostream> #include <tuple> #include <string> #include <map> #include <vector> using namespace std; using Info = std::tuple<std::string, int, Read more…
Git will show conflicts if there are many spaces in the same file. It can spend too much time to fix these conflicts if the spaces are too many. Use git help merge to refer to the manual page. ignore-space-change, ignore-all-space, ignore-space-at-eol, ignore-cr-at-eol Treats lines with the indicated type of Read more…

I want to write a bash script to listen for CPU resource usage. If there is a long time for high CPU consumption, the script will kill the relevant process. I refer to the qustion https://unix.stackexchange.com/questions/66786/bash-script-that-automatically-kills-processes-when-cpu-memory-usage-gets-too-hi on the stackexchange.
