What this gravity tool does

Gravity Points simulates motion using a particle field and user-controlled attractors. Each gravity point pulls particles toward itself, creating fluid, organic motion patterns. Points can merge, collapse, and dynamically alter particle paths in real time.

Key features for developers

  • HTML5 Canvas rendering with lightweight JavaScript logic.
  • Interactive controls: click to create, drag to reposition, double-click to collapse.
  • Particle trail rendering with buffer-canvas fade effects.
  • Dynamic gravity interactions between points and particles.
  • Built-in `dat.GUI` controls for particle count and interference behavior.
  • Fast setup for landing pages, hero sections, and fullscreen demos.

How Gravity Points works internally

1. Vector math engine

The tool uses a reusable `Vector` model for all motion calculations such as distance, normalization, angle, and interpolation. This keeps the physics loop predictable and easy to extend.

2. GravityPoint objects

Each point applies attraction forces to nearby particles and can absorb other points when overlapping conditions are met. Radius growth and collapse logic produce evolving visuals with minimal code.

3. Particle update loop

Particles store current and previous positions to draw smooth trail lines per frame. Speed caps prevent erratic movement and keep animation stable on larger screens.

4. Render pipeline

A main canvas + buffer canvas technique maintains glow and motion persistence without expensive post-processing. This is useful when embedding the effect into production pages.

Integration example

<link rel="stylesheet" href="/tools-code/gravity-points/style.css">
<canvas id="c"></canvas>
<script src="/tools-code/gravity-points/dat.gui.min.js"></script>
<script src="/tools-code/gravity-points/script.js"></script>

Use cases for apps, websites, and software projects

  • Hero backgrounds for software product landing pages.
  • Interactive onboarding screens for web apps.
  • Marketing campaign visuals that increase session duration.
  • Developer portfolio projects and technical showcases.
  • Conference/demo booth displays and kiosk loops.
  • Creative loading or transition states in single-page apps.

Why teams use this as a lead magnet

Developers search for production-ready visual effects they can ship quickly. Offering source code by email turns high-intent tool traffic into qualified leads while still delivering immediate value.

FAQ

Can I use this in commercial projects?

Yes. Submit your email to receive the source package and implementation notes.

Does it work on mobile?

Yes. The canvas resizes to viewport dimensions and supports touch-style interaction equivalents when adapted.

Can I customize colors and particle density?

Yes. The script exposes background, particle radius, and particle count settings, including a live GUI panel.
