PLY files issues at reading and writing about draco HOT 4 CLOSED

Hi. Thanks for the report. Can you please send us test models for both cases? (PLY models that Draco failed to load and PLY model created by Draco that couldn't be loaded in MeshLab).

We have been testing our output models in MeshLab and we are not aware of any issues with this workflow.

1. Please find attached "head1.ply" in the ZIP container which corresponds to one PLY file which is not supported by the DRACO encoder but that can be loaded/diplayed by Meshlab ([64 bits / v1.3.4] or [64 bits / v2016.12]) without issue.
   head1.zip

2. At the decoder side and according to the command lines below, the "bun_zipper_rec.ply" cannot be read by Meshlab ([64 bits / v1.3.4] or [64 bits / v2016.12]) by using your own "bun_zipper.ply" as input mesh. The "bun_zipper.ply" file is the one located in the "testdata" directory provided in the DRACO package.

./draco_encoder.exe -i ../../testdata/bun_zipper.ply -o bun_zipper.drc
./draco_decoder/exe -i bun_zipper.drc -o bun_zipper_rec.ply

I‘ve met the same issue.
I can not open the decoded .ply file either.

We found a problem with .ply encoding on windows builds. It has been fixed and the decoded files should now be readable by Meshlab. Thanks for the report!

As for decoding the "head1.ply". The file is encoded in "format binary_big_endian" which is not supported by Draco. Currently, Draco supports only "format binary_little_endian" and "format ascii". You can probably convert your mesh to the little endian format in Meshlab. We plan to add support for the big endian format in future.
