BPA_Library for iOS

Overview

This project modifies the Ball Pivoting Algorithm (BPA) module from Open3D to make it compatible with PCL (Point Cloud Library) and usable in iOS projects. The library enables high-quality mesh reconstruction from point clouds.

Features

• Optimized for PCL: The BPA module has been adapted to work seamlessly with PCL.
• iOS-ready: The library is tailored for iOS development and can be built using an appropriate toolchain.
• Efficient mesh reconstruction: Generates meshes from input point clouds.

Requirements

This project depends on several third-party libraries. Their source code is not included in this repository. Please acquire and build these libraries separately:

• PCL (Point Cloud Library)
• Boost
• FLANN
• Qhull
• LZ4

Installation

Step 1: Install dependencies

1. PCL: Follow the build instructions at PCL GitHub.
2. Boost: Download and build Boost from Boost.org.
3. FLANN: Follow the instructions at FLANN GitHub.
4. Qhull: Build Qhull from Qhull.org.
5. LZ4: Download and build LZ4 from LZ4 GitHub.

Step 2: Build the BPA library

Use the provided CMakeLists.txt file to build the library for iOS. Ensure that the necessary toolchain and dependencies are correctly set up.

mkdir build-ios
cd build-ios
cmake -DCMAKE_TOOLCHAIN_FILE=../iOS.cmake ..
make

Usage

Integrate the resulting static library into your iOS project. Use the BallPivoting class and the RunBPA function to perform mesh reconstruction from point clouds and their normals.

Example

Below is an example output of the Ball Pivoting Algorithm applied to a point cloud:

The above image showcases the reconstructed mesh of a bunny model generated using this library.
