Following on from last week's GPT 5.5 experiments...

Did more experimenting with HTML-in-Canvas to create more interesting page transitions

Using our favourite animation library GSAP + the PixiJS Skills

Very impressed with how well GPT 5.5 can create WebGL/WebGPU shaders

[PixiJS @PixiJS]

Been testing GPT 5.5 and it's implemented the HTML-in-Canvas spec
Worked for both WebGL and WebGPU out of the box

Then created this demo with the PixiJS + GSAP Skills

Hopefully there will soon be no excuses to make boring websites

Big week for PixiJS

• v8.18.0 released (SVG export, alpha masking, WebGL + WebGPU improvements)
• reached 500k weekly downloads 🎉

And… PixiJS Skills are live.

They can be use with your agent of choice @cursor_ai, @claudeai, @OpenAI, @github.

[PixiJS @PixiJS]

Experimenting with the pretext library... saw a brick breaker demo and had to try making it in PixiJS.

Wanted to see what happens when you add WebGL/WebGPU shaders to the mix.

Using bloom, glow, rgb split filters from pixi-filters.
plus gsaps physics plugin for the text effect.

[PixiJS @PixiJS]

PixiJS v8.17.0 is out 🎉

• Major improvements to text rendering
• BlurFilter optimized for WebGL + WebGPU (faster + better quality)
• tagStyles support in SplitText
• Lots of bug fixes across Graphics, filters, and more

[PixiJS @PixiJS]

Working on an inner shadow filter for the next release.

Great for matching Figma mockups and adding subtle depth to UI elements.

Still working on the best way to showcase the effect...

[PixiJS @PixiJS]

We’ve been looking at refreshing our examples.

Our current ones are… let’s say… very developer designed.

We are definitely not designers. We prefer writing rendering engines. So this is slightly outside our comfort zone 😅

[PixiJS @PixiJS]

PixiJS v8.16.0 is out 🎉

- Return of Canvas 2D renderer
- Tagged text for inline styling
- Major SplitText improvements
- Cube textures, external textures, mip level rendering
- Broad engine stability updates

Plus a small preview for 3D 👀

Beginning the performance optimisation journey!

Currently rendering ~200,000 objects, all automatically batched. No manual setup required, the engine optimises the scene for you.

[PixiJS @PixiJS]

Early experiments with PBR materials, lighting, and shadows as we explore native 3D in PixiJS.

Still rough around the edges, but the rendering pipeline is taking shape.

[PixiJS @PixiJS]

Sometimes you just need a little sprinkle of 3D in your 2D
Started exploring that today, watch this space!

[PixiJS @PixiJS]

The canvas renderer is coming back in the next PixiJS release.

This has been requested by the community since v8, and thanks to an awesome community contribution, it’s now a reality!

[PixiJS @PixiJS]

New year, new PixiJS features ✨

The next release introduces multi-style text: apply multiple styles inside a single text string.

No more splitting text just to highlight a word!

[PixiJS @PixiJS]
