About this tool
3D Portal is a free online visual effect. A glowing ring frames a swirling energy disc whose texture churns in polar coordinates while particles are drawn into the portal. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
When opening the page, a rotating energy whirlpool portal will be displayed. The portal has a swirling energy effect inside, and the edges will emit dazzling light. Parameters such as door color, rotation speed, and energy intensity can be adjusted.
The whole process is pure front-end animation, based on Three.js 'ring geometry and custom shaders, and uses a noise function to simulate the effect of vortex energy.
Suitable for use as science fiction decoration, fantasy themed web pages, or purely appreciating the cool effects of the portal. The implementation principle is the noise function plus the torus geometry.
3D Portal is a science fiction portal special effect based on Three.js that simulates a rotating energy whirlpool portal.
