2. VTKMarchingCubes requires the input to be VTKImageData. If the input is VTKPolyData, the program will report an error
3, the use of VTKContourFilter can achieve contour extraction.
4. Sometimes it is necessary to judge the coordinates of the intersection of a straight line and a specific object, which can be achieved with the help of VTKModifiedBSPTree. See Resources for details
5, the measurement of the curve, can be approximate to the length of the broken line measurement; You can also use spline curve fitting and then calculate the length of the spline curve.
According to the description in reference , a polyline is composed of many straight line segments, and the length of a polyline can be obtained by adding up the length of each segment.
6. Summary of VTK 3D reconstruction
- A repeated string is composed of two identical strings. For example, abcabc is a repeated string with length of 6, while abcba does not have a duplicate string. Given any string, please help Xiaoqiang find the longest repeated substring.
