Web Wave Designer

Expert in creating realistic, performant ocean and water wave effects for web applications using SVG filters, CSS animations, and layering techniques. Specializes in aquatic visuals from gentle ripples to dramatic ocean swells, with particular expertise in the physics of light refraction through water.

When to Use This Skill

Use for:
- Ocean wave backgrounds and seascapes
- Underwater distortion/refraction effects
- Beach shore waves with foam
- Pond/pool ripple animations
- Liquid glass UI effects
- Water-themed loading states
- Parallax ocean layers with depth
- Stylized/cartoon water for games
- Reflection effects on water surfaces

Do NOT use for:
- 3D volumetric ocean rendering -> use WebGL/Three.js/Ocean.js
- Real-time fluid simulation -> use canvas physics engines
- Video effects -> use video editing software
- Simple blue gradients without motion
- Water droplet physics -> use particle systems

Core Distinction: turbulence vs fractalNoise

CRITICAL: For water effects, use type="turbulence" (NOT fractalNoise like clouds):

<!-- WATER - use turbulence -->
<feTurbulence type="turbulence" baseFrequency="0.01 0.1" />

<!-- CLOUDS - use fractalNoise -->
<feTurbulence type="fractalNoise" baseFrequency="0.01" />

SVG Filter Pipeline for Water

The fundamental water effect filter chain:

Source -> feTurbulence -> feDisplacementMap -> feComponentTransfer -> feComposite
            (waves)        (distortion)         (color/opacity)      (blend)

1. feTurbulence - Wave Pattern Generation

<feTurbulence
  type="turbulence"           <!-- MUST be turbulence for water -->
  baseFrequency="0.01 0.1"    <!-- TWO values: x-freq y-freq -->
  numOctaves="3"              <!-- 2-5: wave complexity -->
  seed="42"                   <!-- Variation (free performance) -->
  result="waves"
/>

baseFrequency Explained (TWO Values):

The ratio matters:
- X << Y: Stretched horizontal waves (ocean)
- X == Y: Circular ripples (pond, pool)
- X >> Y: Vertical striations (waterfall)

2. feDisplacementMap - Refraction Effect

Creates the bending/distortion that makes content behind water appear to ripple.

<feDisplacementMap
  in="SourceGraphic"          <!-- What gets distorted -->
  in2="waves"                 <!-- Distortion pattern (from turbulence) -->
  scale="20"                  <!-- 10-40 for realistic refraction -->
  xChannelSelector="R"        <!-- Which color channel drives X displacement -->
  yChannelSelector="G"        <!-- Which color channel drives Y displacement -->
  result="refracted"
/>

3. feComponentTransfer - Water Color

Transform noise into water-like colors by manipulating channels.

<feComponentTransfer in="waves" result="waterColor">
  <feFuncR type="linear" slope="0.3" intercept="0"/>     <!-- Reduce red -->
  <feFuncG type="linear" slope="0.7" intercept="0.2"/>   <!-- Boost green -->
  <feFuncB type="linear" slope="1.2" intercept="0.3"/>   <!-- Strong blue -->
  <feFuncA type="linear" slope="0.6" intercept="0.3"/>   <!-- Water opacity -->
</feComponentTransfer>

4. feGaussianBlur - Caustics (Underwater Light)

<feGaussianBlur
  in="waves"
  stdDeviation="2"            <!-- 1-5 for soft caustic patterns -->
  result="caustics"
/>

5. Compositing - Layer Assembly

<feFlood flood-color="#0077be" flood-opacity="0.4" result="baseWater"/>
<feBlend in="caustics" in2="baseWater" mode="screen" result="waterLayer"/>
<feComposite in="waterLayer" in2="SourceGraphic" operator="over"/>

Animation Techniques

JavaScript requestAnimationFrame (Smoothest)

const turbulence = document.querySelector('#seaFilter feTurbulence');
let frame = 0;

function animateWaves() {
  frame += 0.003;

  // Gentle breathing motion
  const xFreq = 0.006 + Math.sin(frame) * 0.002;
  const yFreq = 0.05 + Math.sin(frame * 0.7) * 0.01;

  turbulence.setAttribute('baseFrequency', `${xFreq} ${yFreq}`);
  requestAnimationFrame(animateWaves);
}

animateWaves();

SVG animate (Declarative, CPU-Heavy)

<feTurbulence baseFrequency="0.01 0.1" numOctaves="3">
  <animate
    attributeName="baseFrequency"
    dur="60s"
    keyTimes="0;0.5;1"
    values="0.008 0.08;0.012 0.12;0.008 0.08"
    repeatCount="indefinite"
  />
</feTurbulence>

WARNING: SVG animate on filter attributes forces full filter recalculation every frame. Use sparingly.

CSS Transform Animation (Best Performance)

Move the water element, not the filter:

.wave-layer {
  animation: wave-drift 20s linear infinite;
}

@keyframes wave-drift {
  from { transform: translateX(0) translateY(0); }
  to { transform: translateX(-50%) translateY(5px); }
}

Seed Animation (Morphing Waves)

Animate seed for shape variation without baseFrequency cost:

<feTurbulence baseFrequency="0.01 0.1">
  <animate
    attributeName="seed"
    dur="20s"
    values="1;50;100;50;1"
    repeatCount="indefinite"
  />
</feTurbulence>

Performance Optimization

Critical Rules

1. Use type="turbulence" - Correct type for water (not fractalNoise)
2. numOctaves <= 4 - Above 4 minimal visual gain, exponential CPU cost
3. Scale 10-30 - Above 40 becomes unrealistic and slower
4. Avoid animating baseFrequency - Use CSS transforms or seed animation instead
5. GPU hints - Add will-change: transform on animated layers
6. Batch SVG defs - One <defs> block, multiple filters

Performance Tiers

Mobile Optimization

@media (prefers-reduced-motion: reduce) {
  .wave {
    animation: none !important;
  }
}

@media (max-width: 768px) {
  /* Reduce to 2 wave layers */
  .wave-1 { display: none; }

  /* Use simpler filter */
  .wave { filter: url(#waveSimple); }
}

Performance Detection

const canHandleWaterEffects = () => {
  // Check for GPU
  const canvas = document.createElement('canvas');
  const gl = canvas.getContext('webgl');
  if (!gl) return 'ultra'; // CSS only

  const debugInfo = gl.getExtension('WEBGL_debug_renderer_info');
  const renderer = debugInfo
    ? gl.getParameter(debugInfo.UNMASKED_RENDERER_WEBGL)
    : '';

  // Integrated graphics = medium tier
  if (renderer.includes('Intel') || renderer.includes('Mali')) {
    return 'medium';
  }

  return 'high';
};

// Apply appropriate tier
const tier = canHandleWaterEffects();
document.body.dataset.waterTier = tier;

/* Tier-based styling */
[data-water-tier="ultra"] .wave {
  filter: none;
  background: linear-gradient(/* simple gradient */);
}

[data-water-tier="medium"] .wave {
  filter: url(#waveSimple);
}

[data-water-tier="high"] .wave {
  filter: url(#waveFull);
}

Framework Integration

Next.js / React

// components/OceanBackground.tsx
'use client';

import { useEffect, useState, useRef } from 'react';
import styles from './OceanBackground.module.css';

export function OceanBackground({ children }: { children: React.ReactNode }) {
  const [mounted, setMounted] = useState(false);
  const turbRef = useRef<SVGFETurbulenceElement>(null);

  useEffect(() => {
    setMounted(true);

    // Animate after mount
    let frame = 0;
    const animate = () => {
      frame += 0.003;
      if (turbRef.current) {
        const xFreq = 0.008 + Math.sin(frame) * 0.002;
        const yFreq = 0.08 + Math.sin(frame * 0.7) * 0.01;
        turbRef.current.setAttribute('baseFrequency', `${xFreq} ${yFreq}`);
      }
      requestAnimationFrame(animate);
    };
    const id = requestAnimationFrame(animate);
    return () => cancelAnimationFrame(id);
  }, []);

  if (!mounted) return null;

  return (
    <div className={styles.ocean}>
      <svg className={styles.filters}>
        <defs>
          <filter id="oceanWave">
            <feTurbulence ref={turbRef} type="turbulence"
                          baseFrequency="0.008 0.08" numOctaves="4"/>
            <feDisplacementMap in="SourceGraphic" scale="25"/>
          </filter>
        </defs>
      </svg>
      <div className={styles.waveLayer} />
      <div className={styles.content}>{children}</div>
    </div>
  );
}

Tailwind CSS

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      animation: {
        'wave-drift': 'wave-drift 60s linear infinite',
        'wave-slow': 'wave-drift 90s linear infinite',
        'wave-fast': 'wave-drift 35s linear infinite',
      },
      keyframes: {
        'wave-drift': {
          from: { transform: 'translateX(0)' },
          to: { transform: 'translateX(-50%)' },
        },
      },
      colors: {
        ocean: {
          deep: '#0c4a6e',
          mid: '#0369a1',
          surface: '#0ea5e9',
          foam: '#f0f9ff',
        },
      },
    },
  },
};

Vue 3

<template>
  <div class="ocean-container">
    <WaveFilters />
    <div
      v-for="layer in waveLayers"
      :key="layer.id"
      class="wave-layer"
      :style="layer.style"
    />
    <slot />
  </div>
</template>

<script setup>
import { computed, onMounted, ref } from 'vue';
import WaveFilters from './WaveFilters.vue';

const waveLayers = computed(() => [
  { id: 1, style: { filter: 'url(#wave1)', animationDuration: '80s', opacity: 0.4 }},
  { id: 2, style: { filter: 'url(#wave2)', animationDuration: '55s', opacity: 0.6 }},
  { id: 3, style: { filter: 'url(#wave3)', animationDuration: '35s', opacity: 0.8 }},
]);
</script>

Debugging Tips

Visualize Filter Pipeline

<!-- Show each filter step -->
<filter id="debug-water">
  <feTurbulence result="step1"/>
  <feImage href="#step1" x="0" y="0" width="200" height="200"/>

  <feDisplacementMap in="SourceGraphic" in2="step1" result="step2"/>
  <feImage href="#step2" x="200" y="0" width="200" height="200"/>
</filter>

Common Issues

Browser DevTools

1. Elements panel > Select SVG filter > Inspect attributes
2. Performance panel > Record > Check for layout thrashing
3. Layers panel (Chrome) > Verify GPU acceleration on wave layers

Integration with web-cloud-designer

For complete atmospheric scenes, combine water and cloud effects:

<div class="scene">
  <!-- Sky with clouds (from web-cloud-designer) -->
  <div class="sky">
    <div class="cloud-layer cloud-back"></div>
    <div class="cloud-layer cloud-front"></div>
  </div>

  <!-- Horizon -->
  <div class="horizon"></div>

  <!-- Ocean with waves (this skill) -->
  <div class="ocean">
    <div class="wave wave-back"></div>
    <div class="wave wave-front"></div>
    <div class="reflection"></div>
  </div>
</div>

<style>
  .scene {
    height: 100vh;
    display: grid;
    grid-template-rows: 60% 40%;
  }

  .sky {
    background: linear-gradient(180deg, #1e3c72 0%, #87CEEB 100%);
  }

  .ocean {
    background: linear-gradient(180deg, #0369a1 0%, #0c4a6e 100%);
  }

  .reflection {
    /* Mirror cloud movement on water surface */
    position: absolute;
    top: 0;
    width: 100%;
    height: 30%;
    background: inherit;
    transform: scaleY(-1);
    opacity: 0.3;
    filter: url(#waterReflection) blur(2px);
  }
</style>
