SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you apply real-time visual effects in PixiJS by configuring the filter pipeline correctly and efficiently, avoiding common performance and configuration pitfalls.

Core Features & Use Cases

  • Built-in filter setup: Configure Alpha, Blur, ColorMatrix, Displacement, and Noise filters and chain them via container.filters for predictable results.
  • Custom shader filters: Create GLSL/WGSL-based filters using Filter.from() (or deeper GlProgram/GpuProgram construction) and drive uniforms safely over time.
  • Performance optimization: Tune resolution, padding, antialias, blendRequired, and filterArea to reduce per-frame bounds measurement and avoid unnecessary back-buffer dependencies.
  • Use Case: Create a sprite “glow/blur + color shift” effect that animates with time while keeping rendering costs stable by setting a known filterArea and using the proper filter bounds configuration.

Quick Start

Use the pixijs-filters skill by setting one or more PixiJS filters on container.filters, then set container.filterArea to a known rectangle to prevent expensive bounds measurement.

Frequently Asked Questions about pixijs-filters

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I apply custom GLSL shaders to a PixiJS container?▼

Apply custom GLSL shaders in PixiJS by using Filter.from() or constructing GlProgram and GpuProgram instances directly, then assigning them to container.filters and driving uniforms safely over time via resource updates.

Why are my PixiJS filter effects causing performance drops?▼

PixiJS filter performance drops often stem from expensive per-frame bounds measurement; set a known container.filterArea rectangle and tune resolution, padding, and antialias settings to stabilize rendering costs.

Can I chain blur and color matrix filters in PixiJS v8?▼

Yes, you can chain built-in Blur and ColorMatrix filters in PixiJS v8 by assigning an array of filter instances to container.filters, producing predictable combined visual effects.

What is filterArea used for in PixiJS?▼

filterArea in PixiJS defines a known rectangle for filter bounds, preventing the engine from performing expensive automatic bounds measurement on the container each frame and ensuring accurate effect rendering.

Do I need to configure blendRequired for WebGL filters?▼

Yes, configuring optional blendRequired and back-buffer handling is necessary for specific WebGL filter effects in PixiJS to render correctly without unnecessary performance overhead.

How do I animate a PixiJS filter uniform over time?▼

Animate PixiJS filter uniforms over time by updating their values per frame with proper resources typing for uniforms and textures, ensuring the GLSL or WGSL custom filter reflects the changes safely.
