How do I create a custom bloom effect in gdx-vfx?

Extend the VfxEffect class and implement your shader logic, or modify the existing BloomEffect; refer to the library's wiki for guidance on custom effect development and shader integration.

gdx-vfx vs libgdx-contribs-postprocessing: which should I use?

gdx-vfx is a refactored, more stable alternative with a simpler API, but if you need a mature library with more community history, libgdx-contribs-postprocessing might be better; check the CHANGES.md for improvements.

Does gdx-vfx support 3D rendering in libGDX games?

Yes, it can apply effects to any rendered output, including 3D scenes, but ensure your rendering pipeline correctly captures frames with VfxManager for post-processing.

What's the performance impact of gdx-vfx on Android?

Post-processing effects consume GPU resources; gdx-vfx is lightweight, but you should profile your game and optimize effect chains, especially for low-end devices to maintain frame rates.

How to fix the iOS asset issue in gdx-vfx?

Follow the workaround in the GitHub issue thread, which involves additional setup steps to bundle asset files properly for iOS runtime, as detailed in the known problems section.

Can I use gdx-vfx for partial screen effects like UI blur?

Yes, but it requires managing multiple VfxManagers or rendering specific layers to off-screen buffers, adding complexity to your rendering code compared to full-screen effects.

gdx-vfx — libGDX Post-Processing Library

What is gdx-vfx?

gdx-vfx is a post-processing visual effects library for the libGDX game development framework. It enables developers to apply shader-based visual effects like blur, bloom, and color correction to their game graphics through a flexible and lightweight pipeline. The library solves the problem of adding professional-grade visual enhancements to 2D and 3D games built with libGDX.

Target Audience

Game developers using libGDX who want to enhance their game's visuals with post-processing effects without implementing complex shader pipelines from scratch.

Value Proposition

Developers choose gdx-vfx because it offers a stable, well-architected alternative to existing post-processing solutions for libGDX, with simpler integration, better documentation, and ongoing maintenance. Its focus on lightweight design and extensibility makes it suitable for both simple and complex visual effect requirements.

libGDX post-processing visual effects

Use Cases

Best For

Adding bloom and glow effects to 2D libGDX games
Implementing screen-wide color grading in libGDX projects
Creating motion blur effects for fast-paced libGDX games
Applying Gaussian blur to UI elements or game backgrounds
Building custom post-processing effect chains for libGDX
Enhancing visual quality in cross-platform libGDX games (desktop, mobile, HTML5)

Not Ideal For

Projects requiring production-ready stability and comprehensive documentation, as gdx-vfx is in beta with poorly documented code.
iOS game development where seamless asset integration is essential, due to known issues requiring manual workarounds for runtime asset availability.
Teams needing a vast library of pre-built visual effects out of the box, as the standard effects module might be limited compared to more mature libraries.

Pros & Cons

Pros

Flexible Effect Chaining

VfxManager allows chaining multiple effects like Gaussian blur and bloom, enabling complex post-processing pipelines as demonstrated in the sample code for layered visual enhancements.

Simple API Design

Effect classes such as GaussianBlurEffect provide easy-to-configure public properties, making implementation straightforward for common visual effects without deep shader knowledge.

Cross-Platform Compatibility

Fully supports desktop, mobile, and HTML/GWT targets with specific dependencies, ensuring wide deployment options for libGDX games across different environments.

Extensible for Custom Effects

Developers can extend base VfxEffect classes to create custom shader-based effects, allowing for tailored visual enhancements beyond the built-in options.

Cons

Beta Status and Documentation Gaps

The README explicitly states the library is in beta with poorly documented code, which can hinder development, debugging, and onboarding for new users.

iOS Integration Hurdles

Known problems require extra steps to make gdx-vfx-effects asset files available on iOS, adding complexity and potential bugs to the setup process.

Limited Built-in Effect Library

While extensible, the standard effects module may not cover all visual needs, potentially forcing developers to build custom effects from scratch for advanced requirements.
