3D HOUSE WIREFRAME DATASET

Description

This project is dedicated to working with 3d house wireframe datasets stored in NPZ files. It includes a Python script for reading and visualizing 3D wireframe data using the Open3D library. The dataset and related scripts are organized to facilitate easy loading, processing, and visualization of 3D wireframes.

• npz/: This directory contains the NPZ files with the 3D house wireframe data.
• read_npz.py: A Python script for reading and visualizing the wireframe data from NPZ files.
• README.md: This file, providing an overview of the project.

Usage

Prerequisites

Make sure you have Python installed along with the necessary libraries:

• open3d
• numpy

You can install these libraries using pip:

pip install open3d numpy

Running the Script

To visualize a 3d house wireframe from an NPZ file, follow these steps:

1. Update the file_path variable in read_npz.py to point to the desired NPZ file.
2. Run the script:

   python read_npz.py

Script Explanation

The read_npz.py script performs the following tasks:

1. Loads the vertices and lines data from the specified NPZ file.
2. Checks if the data is correctly loaded.
3. Creates a LineSet object using Open3D.
4. Visualizes the wireframe using Open3D's visualization tools.
