name	mengto-globe-particles
description	Create a globe-like 3D particle visualization with a dense luminous spherical core and thinner orbital ring or flattened disc. Use when a design needs a premium planetary, orbital, synthesized data-globe effect rendered with real WebGL/Three.js particles, not generic starfields or full page layout changes.

Globe Particles

Scope

• Apply only to a globe-like 3D particle visualization.
• Do not change full page layout, copy, or unrelated motion systems.
• Use for planetary, orbital, infrastructure, or synthesized data-globe effects.
• Keep the core neutral or white-hot and derive ring/glow accents from the design's primary color.

Visual Target

• Dense spherical core of luminous points.
• Thinner outer orbital ring or flattened disc around the sphere.
• Clear globe silhouette with tilt, depth, and layered particle density.
• Dark atmospheric background, restrained glow, clean structure, and subtle sci-fi depth.
• Premium and cinematic, not playful or noisy.

HTML And CSS

<div class="globe-particles-shell">
  <canvas class="globe-particles-canvas" data-globe-particles></canvas>
</div>

.globe-particles-shell {
  position: relative;
  width: min(100%, 760px);
  aspect-ratio: 1 / 1;
}

.globe-particles-canvas {
  position: absolute;
  inset: 0;
  width: 100%;
  height: 100%;
  display: block;
  pointer-events: none;
}

Particle Shader

Use circular shader points so particles stay crisp and luminous.

const globeParticleVertex = `
attribute float a_size;
attribute float a_layer;

uniform float u_time;
uniform float u_pointSize;

varying float v_layer;
varying float v_depth;
varying float v_falloff;

void main() {
  vec3 pos = position;
  float breathe = 1.0 + sin(u_time * 0.65 + a_layer * 4.0) * 0.012;
  pos *= breathe;

  vec4 mvPosition = modelViewMatrix * vec4(pos, 1.0);
  gl_PointSize = u_pointSize * a_size * (1.0 / max(0.18, -mvPosition.z));
  gl_Position = projectionMatrix * mvPosition;

  v_layer = a_layer;
  v_depth = smoothstep(-1.8, 1.8, pos.z);
  v_falloff = smoothstep(2.45, 0.25, length(pos));
}
`;

const globeParticleFragment = `
precision highp float;

uniform vec3 u_coreColor;
uniform vec3 u_accentColor;

varying float v_layer;
varying float v_depth;
varying float v_falloff;

void main() {
  vec2 uv = gl_PointCoord - 0.5;
  float d = length(uv);
  float alpha = smoothstep(0.5, 0.0, d);
  alpha *= alpha;

  vec3 color = mix(u_coreColor, u_accentColor, smoothstep(0.35, 1.0, v_layer));
  color += vec3(1.0) * v_depth * 0.08;
  color = mix(color * 0.42, color, clamp(v_falloff + v_layer * 0.28, 0.0, 1.0));
  alpha *= mix(0.52, 1.0, clamp(v_falloff + v_layer * 0.24, 0.0, 1.0));

  gl_FragColor = vec4(color, alpha);
}
`;

Tuning Knobs

• Density: tune sphereCount and ringCount separately.
• Scale: tune radius, ringRadius, ringThickness, and cameraDistance.
• Color: keep coreColor neutral; derive accentColor from the brand primary.
• Motion: tune rotationSpeed, tiltX, tiltZ, mouseStrength, and breathing amplitude.
• Glow: tune pointSize, additive blending, and particle count so the shape stays crisp.
• Performance: lower particle counts or cap maxDpr before changing the visual structure.

Taste Rules

• The silhouette must read as a globe, not a loose starfield.
• The ring should feel orbital and tilted, not like a flat decorative underline.
• Use restrained glow; let density and depth create the premium feel.
• Keep mouse response gentle so the object drifts rather than swings.
• Put the globe over a dark background or inside a dark atmospheric shell.

Avoid

• Generic starfield noise with no spherical structure.
• Oversized particles or bloom that destroys the globe silhouette.
• Hardcoded accent colors when the design has a clear primary color.
• Wild cursor interaction or fast spinning.
• Dense fog that turns the object into a blurry blob.

Quick Checks

• Sphere and ring are distinct particle populations.
• Core reads mostly neutral or white-hot.
• Accent color appears on ring, highlights, or glow.
• Tilt reveals the ring and globe depth.
• Reduced motion renders a still or near-still object.
• Geometry, material, renderer, listeners, and RAF are cleaned up.
