Point cloud simulation with Blensor

This repository hosts the simulation code originally from Points2Surf. It simulates point clouds from individual meshes with BlenSor, and generates sets of query points with known signed distance values in the meantime.

Usage

Configuration

Configure simulation runtime settings in ./conf/blensor.yaml, and dataset-specific configuration in ./{dataset}/settings.ini.

Simulation

Three sensor perspective presets are available with the parameter perspective:

# simulate point clouds from upper part of meshes
python simulate perspective='upper'

# simulate point clouds from only top of meshes
python simulate perspective='top'

# simulte point clouds all around meshes
python simulate perspective='full'

Misc

./misc/hdf5.py and ./misc/split.py are two scripts for HDF5 file creation and filelist split, with configurations in ./conf/hdf5.yaml and ./conf/split.yaml, respectively.
