Open Source GLSL (OpenGL Shading Language) Software Development Software

Replica Dataset is a high-quality 3D dataset of realistic indoor environments designed to advance research in computer vision, robotics, and embodied AI. Developed by Facebook Research (now Meta AI), it features accurate geometric reconstructions, high-resolution and high dynamic range textures, and comprehensive semantic annotations. Each environment contains detailed models of real-world spaces, including rooms, furniture, glass, and mirror surfaces. The dataset also provides semantic and instance segmentations, planar decomposition, and navigation meshes, making it highly suitable for simulation, visual perception, and autonomous navigation tasks. Replica integrates seamlessly with AI Habitat, Meta’s framework for embodied AI training, enabling large-scale agent simulation and photorealistic rendering for reinforcement learning and robotics. Researchers can use Replica’s ReplicaViewer to interactively explore the 3D scenes.

OpenGL Mathematics (GLM) is a C++ mathematics library for 3D software based on the OpenGL Shading Language (GLSL) specification.

The glVertex library emulates the legacy OpenGL API, which has been deprecated in OpenGL core profiles. It is also a convenience wrapper around GLSL shaders, VBOs and FBOs.

The Perl OpenGL 2 module provides bindings to the modern OpenGL APIs for use from the perl language.

It read opengl pixel shader from txt file, and draw big square on whole screen using that shader. Like shadertoy.com

ExplorViz is a web-based software visualization for large software landscapes. It features two different perspectives: the landscape-level perspective and the application-level perspective. The former visualizes the systems, nodes, and application existing in the software landscape. The latter one utilizes the city metaphor to visualize the entities and communication happening in one application. For installation instructions and downloads see http://www.explorviz.net

It's engine for creating procedural graphics (GFX) in 4kb exe files. Aiming for demoscene parties.

This encapsulates some of the higher level functions of OpenGL using extensions into C++ objects. These at the moment in time are framebuffer objects and shaders

LYGIA is a shader library of reusable functions that will let you prototype, port or ship a project in just few minutes. It's very granular, flexible and efficient. Supports multiple shading languages and can easily be added to any project, environment or framework of your choice.

Lullaby is a modular collection of high-performance C++ libraries developed by Google for creating immersive virtual and augmented reality (VR/AR) experiences. It provides a flexible framework built around an Entity-Component-System (ECS) architecture, enabling developers to design efficient, scalable, and data-driven 3D applications. The framework includes tools and APIs for rendering full 3D environments, managing spatial audio, handling animations, and constructing interactive UI elements optimized for VR interfaces. Lullaby’s design promotes rapid iteration and cross-platform deployment, offering support for Android, iOS, Linux, and Windows. It integrates seamlessly with existing Android applications through a Java-based API and supports popular VR platforms such as Google Cardboard and Daydream. Originally used across multiple Google VR products, Lullaby serves as a foundation for building interactive worlds, responsive UIs, and dynamic simulations within immersive environments.

Collection of useful classes and functions.

Stoolkit is crossplatform simulation toolkit providing GUI and tools for 2D, 3D Graphics, Audio

XSquare is a graphics engine and toolkit with a variety of features. I created this for use in other projects of mine.

iSDGE is meant to be a free next generation 3D game engine for mobile devices supporting OpenGL ES 2.0. It is very easy to use, extremely flexible and fast. iSDGE is mostly written in C++ and currently comes with an Objective-C binding for iOS.
