Open Source C++ Libraries for Windows

The OpenGL Extension Wrangler Library is a simple tool that helps C/C++ developers initialize extensions and write portable applications. GLEW currently supports a variety of operating systems, including Windows, Linux, Darwin, Irix, and Solaris.

This is a C++ header-only library to provide an IEEE-754 conformant half-precision floating point type along with corresponding arithmetic operators, type conversions and common mathematical functions. It aims for both efficiency and ease of use, trying to accurately mimic the behaviour of the builtin floating point types at the best performance possible. It automatically uses and provides C++11 features when possible, but stays completely C++98-compatible when neccessary.

A multi-platform software synthesiser emulating (somewhat inaccurately) pre-GM MIDI devices such as the Roland MT-32, CM-32L, CM-64 and LAPC-I. In no way endorsed by or affiliated with Roland Corp. Source hosted at: http://www.github.com/munt/

FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. FastLED is used by thousands of developers, in countless art and hobby projects, and in numerous commercial products. We build FastLED to help you get started faster, develop your code faster, and make your code run faster. FastLED supports popular LEDs including Neopixel, WS2801, WS2811, WS2812B, LPD8806, TM1809, and more. The library runs on a wide range of Arduino and compatible boards, including both AVR- and ARM- based microcontrollers. In addition to fast, efficient, compatible LED driver code, FastLED also provides features that get your animations up and running fast.

Open3D is an open-source library that supports rapid development of software that deals with 3D data. The Open3D frontend exposes a set of carefully selected data structures and algorithms in both C++ and Python. The backend is highly optimized and is set up for parallelization. Open3D was developed from a clean slate with a small and carefully considered set of dependencies. It can be set up on different platforms and compiled from source with minimal effort. The code is clean, consistently styled, and maintained via a clear code review mechanism. Open3D has been used in a number of published research projects and is actively deployed in the cloud. We welcome contributions from the open-source community. GCC 5.X and later on Linux. XCode 10+ and later on OS X 10.14+. Visual Studio 2019 and later on Windows.

The Simd Library is a free open source image processing library, designed for C and C++ programmers. It provides many useful high performance algorithms for image processing such as: pixel format conversion, image scaling and filtration, extraction of statistic information from images, motion detection, object detection (HAAR and LBP classifier cascades) and classification, neural network. The algorithms are optimized with using of different SIMD CPU extensions. In particular the library supports following CPU extensions: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2 and AVX-512 for x86/x64, VMX(Altivec) and VSX(Power7) for PowerPC, NEON for ARM. The Simd Library has C API and also contains useful C++ classes and functions to facilitate access to C API. The library supports dynamic and static linking, 32-bit and 64-bit Windows, Android and Linux, MSVS, G++ and Clang compilers, MSVS project and CMake build systems.

A fast JPEG2000 encoder running on CUDA-capable GPUs. Supports lossless and lossy encoding. Both commandline tool with GUI and CUDA/C++ library. Visit >> http://cuj2k.sourceforge.net << for further information.

This project has moved to GitHub: https://github.com/ubershader/GLSlayer OpenGL Sanity Layer is an object-oriented 3D graphics API on top of OpenGL written in C++. It is designed not just to provide an encapsulation of OpenGL objects, but to provide a cleaner and more streamlined interface similar to Direct3D and hide some of OpenGL's weak spots such as bind-to-edit semantics, multiple stage object creation, unavailability of platform independent initialization and loading of extensions to expose features. With GLSlayer it is easy to create a rendering context just by filling a structure and calling a function. All extensions needed to expose features for requested OpenGL version are loaded automatically. The code needed to create, setup and use objects is reduced and made intuitive. It supports OpenGL versions from 3.3 to 4.3, only forward compatible contexts.

GLSLmath provides C++ math operations as defined by GLSL. For example, it provides methods to easily setup viewing transformations and perspective projections. GLSLmath has been inspired by the glm and slmath libraries, which aim to mimic GLSL, but in contrast to those GLSLmath does not focus on a complete conforming implementation of GLSL. It rather aims to provide a convenient single header file that implements the most commonly used subset of GLSL so that it is easy to use for rapid prototyping and GLSL teaching purposes. It is used at the Georg-Simon Ohm University of Applied Sciences in Nuremberg for teaching computer graphics courses.
