fx2x

fx2x is a fictional open-source framework described here to illustrate a concise wiki-style entry. It does not correspond to a real product or standard.

Overview

fx2x is a cross-platform library for building 2D graphics applications and user interfaces. It provides a scene graph for organizing visual elements, a transform system for position, rotation, and scale, a rendering backend abstraction, and resources management for textures, fonts, and animations. The framework emphasizes simplicity and deterministic rendering suitable for games, tools, and visual editors.

Architecture

The core consists of a scene graph of nodes, including primitives such as sprites, shapes, and containers. Each node supports local and world transforms, visibility, and event handling. Rendering backends can be swapped (software rasterizer or GPU-accelerated pipelines). An asset manager loads and caches resources, while a lightweight animation system provides tweening and sequencing. FX2X also offers a small domain-specific language for simple shader-like effects used during rendering.

Language bindings and usage

The core is implemented in C++ with bindings for Python and Lua, enabling rapid prototyping and integration into existing tools. Applications create a scene, configure properties with an API, and run a synchronous or asynchronous render loop. FX2X is designed to be minimal yet extensible, allowing developers to plug in custom input handlers and exporters to common formats.

Development and status

As a hypothetical example, fx2x is often used in documentation and tutorials to demonstrate design patterns for UI frameworks and 2D engines. It has no official release or governance, and no real-world ecosystem beyond the descriptive article.
