How to draw figure-3? #3

Closed Ruye-aa closed 2 years ago

Ruye-aa commented 2 years ago

Hi, this is amazing work. I am trying to reproduce the results in your paper. But I encountered a problem when trying to draw Figure 3 in the paper. I learned the knowledge of open3D, but I still don't know how to display the two registered point clouds on one map and connect the corresponding points with lines. I would like to ask if you can provide the source code of Figure 3, or tell me what method and function I can use to draw the effect of Figure 3. As a beginner in the field, I know this question may be simple, but I'd still appreciate to get your help. Thanks！ 0

Hi, thanks for your interest!

For drawing lines with Open3D, you can check the example given here: 1642763232(1) More examples about visualization can be found here: http://www.open3d.org/docs/0.7.0/tutorial/Basic/visualization.html. You can also check the demo (demo.py) of FCGF (https://github.com/chrischoy/FCGF).
