About 3D Raymarching Sphere
3D Raymarching Sphere is an interactive 3d effects effect. A full-screen fragment shader marches a ray per pixel toward a rippling sphere, computing normals and lighting in real time. Adjust camera angles, lighting, and parameters to explore the 3D scene from any perspective. The real-time rendering delivers smooth visual performance directly in your browser. This effect runs directly in your browser using Three.js and WebGL, with no downloads or plugins required.
How to Interact
Click and drag to rotate the 3D scene in any direction. Scroll to zoom in and out. Move your mouse to interact with objects and particles in the 3D space. On mobile, use touch gestures to rotate and pinch to zoom.
Technical Details
Built with Three.js and WebGL. Uses perspective camera rendering, real-time GPU shaders, and mouse-driven camera controls. The 3D scene is rendered with hardware acceleration for smooth performance. Supports touch interaction on mobile devices.
Use Cases
Ideal as an interactive 3D background for websites, creative coding reference for Three.js developers, or recording showcase clips for social media content. Also useful for learning WebGL rendering techniques.
