Open-source alternatives to Heaps

A C/C++ single-file library that minimizes the hard transition errors of disjoint edges in lightmaps. It is based on a idea presented by Michał Iwanicki in the talk Lighting Technology of "The Last Of Us". A least squares solver is used to find a minimal error solution to the problem of sampling…

Package aseprite implements a decoder for Aseprite sprite files (.ase and .aseprite files).

Cross-platform 2D framework written in Haxe that can export natively to desktop (windows, mac, linux), mobile (ios, android), web (js webgl) and to unity projects

Assimp is a cross-platform 3D asset pipeline and import library that loads numerous industry-standard 3D file formats into a single unified internal data structure. It functions as a framework for converting 3D models between different file formats across multiple operating systems and architectures. The project provides a 3D mesh processing tool for normalizing and optimizing geometry through triangulation, vertex removal, and normal generation. It also includes a 3D asset export utility to write internal scene data back into various external file formats. The system covers broad capability

A C header file & shader for simulating colourblindness and checking contrast.

Babylon.js is a JavaScript game engine and real-time graphics renderer designed for creating interactive three-dimensional visuals and applications. It functions as a web-based 3D framework and WebGL engine that enables the deployment of high-performance 3D content across various web platforms and devices. The project provides tools for web-based 3D game development, real-time graphics rendering, and the creation of browser-based interactive visualizations. It also supports the development of WebXR virtual and augmented reality experiences using standard web technologies. The framework cover

Bevy is a cross-platform game engine and framework built in Rust, designed for creating interactive simulations and graphical applications. It utilizes a data-oriented entity-component-system architecture to manage game state, organizing data into contiguous memory blocks to facilitate high-performance processing and massive parallelization of entities. The engine distinguishes itself through a modular plugin architecture and a system-based task scheduler that automatically parallelizes logic by analyzing data access patterns. By employing reactive change detection and deferred command buffer

Lua Virtual Reality Framework

bgfx is a cross-platform, graphics rendering abstraction layer designed for high-performance applications. It provides a unified interface that maps high-level rendering commands to native graphics APIs, allowing developers to maintain a single codebase that executes consistently across diverse operating systems and hardware architectures. The library distinguishes itself through a multi-threaded command submission model that decouples rendering logic from the main application thread, effectively minimizing CPU bottlenecks. It utilizes a backend-agnostic command buffer and a deferred resource

2D Vector Graphics Engine Powered by a JIT Compiler

armory

Minimal three.js alternative.

Simple single header modular library for font rendering and atlas management.\ The library is designed to be lightweight, RFont.h itself does not directly handle rendering calls, it passes raw data to the user defined renderer.

As of 5/28/2024, RGL is no longer going to be actively updated

EaselJS is a JavaScript library for creating interactive 2D graphics and animations using the HTML5 Canvas element. It functions as a 2D animation framework, a canvas scene graph manager, and an interaction wrapper for detecting and responding to mouse and touch events. The library features a rendering pipeline that utilizes WebGL to increase the drawing performance of bitmap and cached content. It organizes visual elements into a hierarchical display list, allowing nested groups of 2D graphics objects to be transformed and animated as single units. Its capabilities cover the rendering of ve

A free, header-only C++ swarming (flocking) library for real-time applications

JavaScript Canvas Framework - Code Creativity! https://zimjs.com

This project is a lightweight, self-contained library for gizmo editing commonly found in many game engines. It includes mechanisms for manipulating 3d position, rotation, and scale. Implemented in C++11, the library does not perform rendering directly and instead provides a per-frame buffer of…

Defold is a cross-platform game engine and integrated development environment used to create 2D and 3D games for desktop, mobile, and web targets. It combines a game development IDE for asset and scene management with a multi-platform build system and a scripting environment based on Lua. The engine includes a specialized headless runtime for hosting game servers and performing automated testing without a graphical interface. It supports native engine extensions, allowing custom low-level code to be integrated into the core to expand functionality beyond the standard scripting interface. The

A display-tree 2D rendering layer for Ebitengine, including scene management, batching, cameras, culling, hit detection, and special effects. Inspired by Starling, Flash display lists, and PixiJS, adapted for Go's strengths.

DiligentEngine is a cross-platform graphics abstraction layer and physically-based rendering engine. It provides a unified interface for executing 3D graphics commands across multiple low-level rendering backends from a single codebase, including a dedicated system for importing 3D assets via the GLTF 2.0 format. The engine features an HLSL shader cross-compiler that allows a single set of shaders to run across different graphics APIs and operating systems. It supports advanced rendering capabilities such as ray-tracing, mesh shaders, variable rate shading, and bindless resources. The framew

This package is a fork of tdewolff/canvas containing changes for game development with Ebitengine. See Diffs from the original section for details.

TIGR is a tiny cross-platform graphics library, providing a unified API for Windows, macOS, Linux, iOS and Android.
