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

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

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…

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.

shapes is a package for Ebitengine (the 2D game library written by Hajime Hoshi) that allows rendering some common shapes and effects in complementary ways to the official vector package. Some examples:

Fabric.js is an object-oriented canvas library that provides an interactive framework for managing shapes, images, and text within an HTML5 canvas environment. It abstracts raw pixel-based drawing commands into a structured hierarchy of objects, enabling developers to manipulate, transform, and animate elements through a centralized event-driven system. The library distinguishes itself by offering comprehensive state serialization, allowing complex graphic compositions to be converted into JSON or SVG formats for persistent storage and reconstruction. It includes a built-in SVG parser that co

3D line art engine.

a ultra lightweight font renderer and font

An immediate-mode, renderer agnostic, lightweight debug drawing API for C++.

This project is a cross-platform library designed for desktop application development, providing a unified interface for window management, input handling, and hardware-accelerated graphics. It serves as a foundational framework that abstracts platform-specific windowing protocols and graphics APIs, enabling developers to create interactive software that functions consistently across Windows, macOS, and Linux. The library distinguishes itself by providing deep integration with low-level graphics APIs, specifically OpenGL and Vulkan. It manages the complexities of graphics context initializati

Filament is a real-time physically based rendering engine designed for high-fidelity 3D graphics. It functions as a cross-platform graphics library that provides a unified interface for rendering complex models and materials across desktop, mobile, and web environments. The engine distinguishes itself through a data-oriented architecture that optimizes memory usage and processing speed, alongside a shader-variant system that generates specialized code for specific material and lighting configurations. By abstracting diverse hardware graphics backends, it ensures consistent visual performance
