How to Install older version of Meshlab?

Ciao Paolo,

thanks for the amazing work with meshlab,

I was trying OccNet, and I run into this issue

output mesh  /home/xxx/Documents/occupancy_networks/external/mesh-fusion/examples/3_out/chair_0893.off
Apply FilterScript: '/home/xxx/Documents/occupancy_networks/external/mesh-fusion/simplification.mlx'
FilterScript
Reading filter with name Simplification: Quadric Edge Collapse Decimation
Starting Script of 1 actionsfilter: Simplification: Quadric Edge Collapse Decimation
meshlabserver: ./src/meshlabserver/mainserver.cpp:375: bool MeshLabServer::script(MeshDocument&, const QString&, FILE*): Assertion `parameterSet.paramList.size() == required.paramList.size()' failed.

Assertion `parameterSet.paramList.size() == required.paramList.size()' failed

I was wondering if I should install a previous version, or is there a better way to fix this problem?

Solution

  • OK the problem was that meshlabserver is only available in 2020.03 that can be installed with sudo apt meshlab. no need to install previous versions

    you need to change that specific simplification.mlx file to match the exact filter, you can follow instruction here https://github.com/cnr-isti-vclab/meshlab/issues/345
