Data

ModelNet10

The ModelNet10 models made watertight using ManifoldPlus can be downloaded here on Zenodo.
The ModelNet10 scans used in our paper can be downloaded here on Zenodo. The dataset also includes training and evaluation data for ConvONet, Points2Surf, Shape As Points, POCO and DGNN.

ShapeNetv1 (13 class subset of Choy et al.)

The watertight ShapeNet models can be downloaded here (provided by the authors of ONet).
Please open an issue if you are interested in the scans used in our paper.

Synthetic Rooms Dataset

The watertight scenes can be downloaded here (provided by the authors of ConvONet).
Please open an issue if you are interested in the scans used in our paper.

Scanning Procedure

You can create point clouds with visibility information of your own dataset using the scan tool. You can use the precompiled scan executable from this repository (which should work on most Ubuntu systems), or compile it youself using mesh-tools.

./scan -w path/to/workingDir -i filenameMeshToScan --export npz

For creating the scans used in the paper the follwing settings were used:

--points 3000 --noise 0.005 --outliers 0.0 --cameras 10

Data Loading

You can use the dataloader.py script to load visibility augmented point clouds from the scan.npz files.

Code and Pretrained Models

You can find our modified code and pretrained models for the surface reconstruction methods tested in our paper below. All methods support point clouds with and without visibility information.
