    Point Cloud Library

    Point Cloud Library

    A standalone, large scale, open project for 2D/3D image processing

    The Point Cloud Library (PCL) is a standalone, large scale, open project for 2D/3D image and point cloud processing. PCL is released under the terms of the BSD license, and thus free for commercial and research use. Whether you’ve just discovered PCL or you’re a long time veteran, this page contains links to a set of resources that will help consolidate your knowledge on PCL and 3D processing. An additional Wiki resource for developers is available too. To simplify both usage and development, we split PCL into a series of modular libraries. PCL is cross-platform, and has been successfully compiled and deployed on Linux, MacOS, Windows, and Android. To simplify development, PCL is split into a series of smaller code libraries, that can be compiled separately. This modularity is important for distributing PCL on platforms with reduced computational or size constraints.

    ESP32 BLE Keyboard library

    ESP32 BLE Keyboard library

    Bluetooth LE Keyboard library for the ESP32

    This library allows you to make the ESP32 act as a Bluetooth Keyboard and control what it does. Compatible with Android. Compatible with Windows. Compatible with Linux. Compatible with MacOS X (not stable, some people have issues, doesn't work with old devices). Compatible with iOS (not stable, some people have issues, doesn't work with old devices). There is also Bluetooth-specific information that you can set (optional): Instead of BleKeyboard bleKeyboard; you can do BleKeyboard bleKeyboard("Bluetooth Device Name", "Bluetooth Device Manufacturer", 100);. (Max length is 15 characters, anything beyond that will be truncated.) By default the battery level will be set to 100%, the device name will be ESP32 Bluetooth Keyboard and the manufacturer will be Espressif. This feature is meant to compensate for some applications and devices that can't handle fast input and will skip letters if too many keys are sent in a small time frame.

    J2ObjC

    J2ObjC

    A Java to iOS Objective-C translation tool and runtime

    J2ObjC is an open-source command-line tool from Google that translates Java source code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java source to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as application logic and data models) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads and reflection. JUnit test translation and execution is also supported. J2ObjC cannot convert Android binary applications. Developers must have source code for their Android app, which they either own or are licensed to use.

    Mapbox GL Native

    Mapbox GL Native

    Interactive, thoroughly customizable maps

    Interactive, thoroughly customizable maps in native Android, iOS, macOS, Node.js, and Qt applications, powered by vector tiles and OpenGL. A C++ library that powers customizable vector maps in native applications on multiple platforms by taking stylesheets that conform to the Mapbox Style Specification, applying them to vector tiles that conform to the Mapbox Vector Tile Specification, and rendering them using OpenGL or Metal. To embed interactive maps into a native application using a platform-specific language, install the Mapbox Maps SDK. We use CMake to build Mapbox GL Native for various platforms, including Linux, Android, iOS, macOS and Windows. The provided command, executed from the root of this repository tree, will build Mapbox GL Native targeting your host architecture given that you have all the dependencies installed and run the example app.

    PetoronHash-System

    PetoronHash-System

    PHASH | post-quantum XOF hashing algorithm | C++20

    PHASH is a self-contained, dependency-free, post-quantum XOF hashing algorithm implemented in modern C++20. This release delivers the first fully stable production implementation of the PetoronHash-System — a 1600-bit sponge-based hash function with domain separation, extendable output, and deterministic behavior. Key Features No external dependencies — pure C++20 implementation. Extendable Output (XOF) — supports arbitrary output length (256–8192+ bits). Post-quantum oriented design — ARX-based sponge resistant to Grover-type attacks. Context and salt separation — unique hashing domains for each use-case. Optimized performance — ~120–130 MB/s Comprehensive verification — verify_all.sh performs KAT tests, determinism checks, and performance validation. Verification Script: chmod +x verify_all.sh ./verify_all.sh https://github.com/01alekseev/PetoronHash-System Ivan Alekseev | petoron.org

    glSatellite Demo

    Technological demo of OpenGL ES 2 Android NDK

    Technological demo of OpenGL ES 2 for Android platform. It reads public NORAD satellite database and shows the satellite positions and altitude related to Earth in the form of beams (the height of the beam represents the relative altitude). NOTE: The project has been moved to GitHub: https://github.com/nuald/glSatellite-Demo The old one stays here just for the historical reasons. The 3D features present: - OpenGL ES 2; - rotating, multi-touch zooming and moving the globe; - stars on a fixed background; - each satellite is represented by a beam with a unique color; - identifying the corresponding satellite if a beam has been tapped (based on color picking method). Additionally to 3D features presented the application is: - using NDK with C++11 features compiled by LLVM clang; - mixing Java views with OpenGL views (Java is used for settings activity, information and ads panels); - using Android custom message queue to send asynchronous messages from Java to JNI
