GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Open WIP: Approximate and exact convex decomposition

iq72ehiq/walberlawork:approximateDecomp into master

Open Tobias Leemann requested to merge iq72ehiq/walberlawork:approximateDecomp into master 6 years ago

Implements approximate and exact decomposition of non-convex meshes into convex parts, which can then be used as a PE-Union.

The approximate decomposition is performed using the V-HACD-Library and the exact decomposition uses the CGAL-Library. This branch implements the interface to walberla and the right transformations from the walberla mesh formats to the formats of the libraries and back.

Update build images to provide CGAl
Update build images to provide vAHCD

@iq72ehiq Images are updated to support CGAl and vHACD. However the tests are failing. Most probably due to numerical inaccuracies in single precision. Can you have a look into it, please.

If you use WALBERLA_CHECK_EQUAL instead of WALBERLA_CHECK, both operands will be printed in the log and you can immediately see the values.
