Surface Reconstruction Demo

Installation

First you have to make sure that you have all dependencies in place. The simplest way to do so, is to use anaconda.

You can create an anaconda environment called tf using

conda env create -f tf.yaml
conda activate tf

Training

You can train a new network from pre-train On-Surface Prior Networks, run

python onSurPrior.py --data_dir ./data/ --out_dir ./train_net/ --CUDA 0 --INPUT_NUM 500 --epoch 30000 --input_ply_file input.ply --train

You should put the point cloud file(--input_ply_file, only ply format) into the '--out_dir' folder, '--INPUT_NUM' is the number of points in the '--input_ply_file'.

Test

You can extract the mesh model from the trained network, run

python onSurPrior.py --data_dir ./data/ --out_dir ./train_net/ --CUDA 0 --INPUT_NUM 500 --epoch 30000 --input_ply_file input.ply --test
