Point Cloud Generator

Point Cloud Generator is a Blender addon designed to generate point clouds and reference camera poses from meshes. It utilizes colors sampled from rendered frames, which can be used in NeRF or 3D-Gaussian reconstruction processes.

Supports Blender 4.0 and higher. This is a work in progress.

Features

• Generate point clouds from selected mesh objects.
• Automatically create camera setups around the object(s) of interest.
• Export generated point clouds in PLY format with associated colors.

Installation

1. Clone or download the repository source.
2. Open Blender and navigate to Edit > Preferences > Add-ons.
3. Click on Install and select the point_cloud_generator.py file.
4. Enable the addon by checking the box next to its name.

3. Navigate to the Tool panel in the 3D View.
4. Expand the Point Cloud Generatory section.
5. Adjust the settings according to your needs (resolution, camera setup, etc.).
6. Click on Generate Point Cloud and Camera Positions to create the point cloud and camera poses.
7. Use the Render Scene and Export Point Cloud to process and export the final data.
