## Submission
In order to submit to the challenge, please create a semantically annotated 3D triangle mesh from the test sequence.
The mesh should be stored in the [PLY text format](http://paulbourke.net/dataformats/ply/).
The file should store for each triangle a color corresponding to the triangle’s semantic class (see the calibrations/colors.yaml file for the mapping between semantic classes and colors).

Once you have created the mesh, please submit it using [this link](https://www.dropbox.com/request/23XzljBTn93zYl3ETjXn).
In addition, please send an email to torsten.sattler@inf.ethz.ch that includes the filename of the file you submitted as well as contact information.
