Thanks for the good work. Very interesting and impressive!

I want to compile with Matlab bindings, and have the issue as follows,

cmake .. -DBUILD_BINDINGS_MATLAB=ON is succeed

but after that, make has an error

Hi,

Thanks for your great work! I have a question regarding the invariant choices. I am using the python API and cannot find a documentation that list different invariant choices.

Right now I am using this clipper.invariants.EuclideanDistanceParams() as in the tutorial. Is there any other already implemented invariant? I know we can implement ourselves.

Hi,

My goal is to find plane correspondences from two sets of planes that are extracted from two different lidar sensors. Is there some maximum rotation that Clipper cannot handle. In my case rotation around z axis is about 90 degrees between lidar sensors

Hello,

I'm trying to compile the MATLAB binaries on Ubuntu 22.04 and I get the following errors:

clipper/bindings/matlab/finddensecluster_mex.cpp:65:37: error: ‘clipper::utils’ has not been declared
   65 |   if (u0.size() == 0) u0 = clipper::utils::randvec(m);
      |                                     ^~~~~
clipper/bindings/matlab/finddensecluster_mex.cpp:74:21: error: ‘findDenseCluster’ is not a member of ‘clipper’
   74 |     soln = clipper::findDenseCluster(Ms, Cs, u0, params);
      |                     ^~~~~~~~~~~~~~~~
clipper/bindings/matlab/finddensecluster_mex.cpp:76:21: error: ‘findDenseCluster’ is not a member of ‘clipper’
   76 |     soln = clipper::findDenseCluster(M, C, u0, params);
      |                     ^~~~~~~~~~~~~~~~

On inspection, it seems findDenseCluster is not a declared function in the C++ code. Am I missing something? How did you compile the MATLAB binaries?

Hello~Thanks for your open source work.

You mentioned in your paper, orthogonal projected gradient ascent are applied. However, in this code

Hi, Thanks for opening great work. I tried to run the python example but I got the error "[Open3D WARNING] Read PLY failed: unable to open file: ../data/bun1k.ply" and the number of points in the point cloud was zero. I tested with another irrelevant PLY file and open3d just worked fine. Are there any suggestions to fix the problem?

Hi,

Thanks a lot for your great work! I have a question regarding the diagonal values in the affinity matrix. The function CLIPPER::setMatrixData sets to zero all of the values in the diagonal entries of M and C matrices. However, in the paper it is explicated that those values measure the similarity of the data points that association. As I have that information, I'd like to be able to use it.

I have tried commenting those lines and making clipper work with my forced values in M_ and C_. However, I'm getting wrong results. Could you please let me know how should I set those values? Thanks in advance!

From the C++ code, I don’t seem to see how to get the rotation and translation matrix. How can I get this correspondence ?
Thank you so much！

Hi, I would like to know how to uninstall clipper safely. I have installed the python bindings and I would like to uninstall it.
