Shape Classification of Building Information Models using Neural Networks

Overview

This repository contains the source code of the short paper presented in 3DOR workshop 2021. Please find below links to

• Author version of the paper
• Video presentation

Repository contents

The project is composed of the following parts :

• An implementation of the solid voxelization algorithm
• The neural network architecture
• A dataset folder with a template for each type of BIM class

Solid Voxelization

A single file implementation of the solid voxelization algorithm. The main source code can be found in :

• voxelizer\src\voxelizer.cpp

Building and running the code will require :

• Visual Studio 2017 or 2019

Neural Network Architecture

A tensorflow 2.4 implementation of the proposed neural architecture can be found in :

• python\src\model.py

An example entry point for training and testing our model can be found in :

• python\train.py
• python\test.py

The augmentation, normalization and alignment function implementations are located in :

• python\src\utils.py
• python\src\dataset_builder.py

An example entry point for creating the dataset is located in :

• python\preprocessor.py

Dataset

In python\dataset\BIM templates directory, one can find the 3D model templates for each one of the 16 classes used for evaluation in the paper.
