Data

We used the ShapeNet dataset for 3D models, and rendered views from 3D-R2N2:

When using the provided data make sure to respect the shapenet license.

The ShapeNet point clouds (*.mat) go in data/customShapeNet_mat
the rendered views (*.png) go in data/ShapeNetRendering

Usage

Train

bash train/train.sh

Generate

python generate.py --model $model_path

Evaluation results

The evaluation is based on 2,048 ground truth points and 2,048 points uniformly sampled from the generated meshes. The CD is multiplied by 1,000 and the EMD is multiplied by 100. The threshold for F-score is set to be 0.002.

Chair	CD	EMD	F-score
