Portal Vortex: an interactive 3D cursor template
A swirling magenta portal that follows the cursor, sparks spiralling off its rim, and bursts open on click.
Try it: Move to pull the portal · click to open it. Open the live Portal Vortex full screen.
Where the Portal Vortex works best
Gaming, sci-fi and fantasy launches, “enter” buttons, and transitions into a product.
How it is built
A full-screen polar shader twists fbm noise more strongly toward the centre; the portal follows the cursor and a click blows it wide open. The whole effect is plain three.js in one module script. It renders only while it is on screen and caps the pixel ratio on high-density displays to protect performance.
Add it to your website
- Add a Code, Embed or Custom HTML block where the effect should sit (Webflow, Framer, WordPress, GoHighLevel, Shopify or plain HTML).
- Paste the snippet. It is one element and one script; three.js loads from a CDN.
- Edit the colours and words in the settings block, then publish.
Frequently asked questions
Is the Portal Vortex template free?
Anyone can open it live and try the interaction. Copying the code is included with a Scrollhaus plan.
Does it work on mobile?
Yes. On touch screens it runs a gentle automatic motion so the scene is never still, and taps trigger the click interaction.
Do I need Spline or three.js experience?
No. It is one HTML element and one module script. Colours, text and images live in a settings block at the top.
