8 JavaScript Mouse Interactions
This collection demonstrates how modern JavaScript transforms standard mouse events into smooth, high-performance interactions. The primary focus is on utilizing requestAnimationFrame and interpolation (lerping) to achieve a flawless 60 FPS, which is critical for lag-free animation quality. You will see how to leverage the Canvas API or SVG for complex visualizations (such as particle systems) with the implementation of basic physics, where the cursor acts as a magnetic field. Furthermore, you will study the conversion of raw coordinates (e.clientX) into three-dimensional CSS spaces (rotate3d) to create advanced parallax and 3D tilt effects, significantly enhancing the user experience.

Shaders Example #15
A highly specialized, GPU-accelerated image transition component built on Three.js.
Hover Interaction (98/100)
A visual illusion of “negative space” where the cursor acts as a physical object parting a dense curtain of threads, revealing the static text underneath.
Wave Text
The text appears as a massive, volumetric block that dynamically adjusts its height and perspective in response to mouse movement, ‘springing’ upon click to create a tactile sensation.
React Animated Custom Cursor
This custom animated cursor implementation employs a dual-layer system where the inner dot follows mouse coordinates instantly via mousemove events, while the outer ring utilizes requestAnimationFrame with coordinate interpolation to create a smooth trailing effect.
Direction-Aware SVG Cursor
This custom SVG cursor rotates dynamically based on the mouse’s velocity and direction, achieved by calculating the angle between the previous and current coordinates using JavaScript’s Math.atan2 and applying the rotation via CSS transform.
Interactive Product Hotspots with GSAP and PIXI.js
Uses the PIXI.js WebGL renderer to draw dynamic, hardware-accelerated connection lines between content hotspots, enhanced by GSAP for the smooth ‘magnetic’ displacement effect upon mouse hover.
Cursor Following Halftone Rings with CSS @property
A cursor effect creating dynamic halftone rings is implemented using CSS Custom Properties and transition properties for smooth mouse-following, requiring minimal JavaScript to update coordinates.
Dynamic Twinkling Particle System with Vanilla JS and Canvas
Dive into an interactive demo using pure JavaScript and Canvas 2D, where mouse movement creates a magnetic field for particles, and clicking triggers an explosion effect, implementing complex element creation and destruction logic.
