Architecture

Architecture

Strata is built as a layered architecture, with each layer building on the previous one. This design provides flexibility—you can use the high-level components for rapid development, or drop down to lower levels for fine-grained control.

Layer 0: Types & Utilities

The foundation layer provides TypeScript type definitions and utility functions used throughout the library.

import type {
  BiomeConfig,
  WaterConfig,
  SkyConfig,
  TerrainChunk
} from '@strata-game-library/core/types';

import {
  clamp,
  lerp,
  smoothstep,
  vec3
} from '@strata-game-library/core/utils';

Layer 1: GLSL Shaders

The shader layer contains all GLSL vertex and fragment shaders. These can be used independently with any Three.js project.

import {
  waterVertexShader,
  waterFragmentShader,
  skyVertexShader,
  skyFragmentShader
} from '@strata-game-library/shaders';

// Use with Three.js ShaderMaterial
const material = new THREE.ShaderMaterial({
  vertexShader: waterVertexShader,
  fragmentShader: waterFragmentShader,
  uniforms: {
    uTime: { value: 0 },
    uWaterColor: { value: new THREE.Color(0x0077be) },
  }
});

Available shader categories:

• Terrain: Height-based blending, triplanar mapping
• Water: Wave animation, reflections, refractions
• Sky: Atmospheric scattering, sun/moon
• Clouds: Volumetric and layered clouds
• Volumetrics: Fog, god rays, underwater
• Materials: Toon, hologram, dissolve, forcefield, glitch
• Vegetation: Wind animation for grass and trees

Layer 2: Core Algorithms

Pure TypeScript implementations of core algorithms with no React dependencies.

SDF (Signed Distance Functions)

import {
  sdSphere,
  sdBox,
  sdCapsule,
  sdTorus,
  opUnion,
  opSubtraction,
  opSmoothUnion
} from '@strata-game-library/core';

// Combine shapes
const scene = opSmoothUnion(
  sdSphere(point, center, radius),
  sdBox(point, boxCenter, boxSize),
  0.5 // smoothness
);

Noise Functions

import {
  noise3D,
  fbm,
  warpedFbm
} from '@strata-game-library/core';

// Generate terrain height
const height = fbm(x * 0.01, 0, z * 0.01, {
  octaves: 6,
  persistence: 0.5,
  lacunarity: 2.0
});

Marching Cubes

import {
  marchingCubes,
  createGeometryFromMarchingCubes,
  generateTerrainChunk
} from '@strata-game-library/core';

// Generate terrain mesh
const geometry = generateTerrainChunk({
  position: [0, 0, 0],
  size: 32,
  resolution: 64,
  sdfFunction: terrainSDF
});

Material Creation

import {
  createWaterMaterial,
  createAdvancedWaterMaterial,
  createSkyMaterial,
  createRaymarchingMaterial
} from '@strata-game-library/core';

const waterMaterial = createWaterMaterial({
  color: new THREE.Color(0x0077be),
  opacity: 0.8,
  reflectivity: 0.5
});

Layer 3: React Components

High-level React Three Fiber components that wrap the core algorithms.

Water Components

import { Water, AdvancedWater } from '@strata-game-library/core';

<Water size={100} depth={20} />
<AdvancedWater
  size={200}
  waveHeight={2}
  reflections
  caustics
/>

Vegetation Components

import {
  GrassInstances,
  TreeInstances,
  RockInstances,
  GPUInstancedMesh
} from '@strata-game-library/core';

<GrassInstances count={10000} spread={100} />
<TreeInstances count={500} spread={200} />

Sky Components

import { ProceduralSky } from '@strata-game-library/core';

<ProceduralSky
  sunPosition={[100, 50, 100]}
  turbidity={10}
  rayleigh={2}
/>

Volumetric Components

import {
  VolumetricEffects,
  VolumetricFogMesh,
  UnderwaterOverlay,
  EnhancedFog
} from '@strata-game-library/core';

<VolumetricFogMesh density={0.02} />
<UnderwaterOverlay depth={10} />

Layer 4: Presets & Game Framework

The highest layer provides ready-to-use configurations and game framework utilities.

Presets

import { createTerrainPreset, TerrainBiomes } from '@strata-game-library/presets/terrain';
import { createWeatherPreset, WeatherPresets } from '@strata-game-library/presets/weather';
import { createWaterPreset, WaterTypes } from '@strata-game-library/presets/water';

const terrain = createTerrainPreset({
  biomes: [TerrainBiomes.GRASSLAND, TerrainBiomes.MOUNTAIN],
  resolution: 128
});

const weather = createWeatherPreset(WeatherPresets.RAIN);
const water = createWaterPreset(WaterTypes.OCEAN);

Game Framework (Coming Soon)

import {
  useGameState,
  useCharacterController,
  useInventory
} from '@strata-game-library/core/game';

Package Structure

Strata is organized as multiple packages for flexibility:

Main Package (@strata-game-library/core)

The core library with components, algorithms, and utilities:

// Main package - components
import { Water, ProceduralSky, Terrain, GrassInstances } from '@strata-game-library/core';

// Subpath: Core algorithms
import { marchingCubes, noise3D, sdSphere } from '@strata-game-library/core';

// Subpath: Utility functions
import { clamp, lerp, smoothstep } from '@strata-game-library/core/utils';

// Subpath: TypeScript types
import type { BiomeConfig, WaterConfig } from '@strata-game-library/core/types';

Shaders Package (@strata-game-library/shaders)

Standalone GLSL shaders (works with any Three.js project):

import {
  waterVertexShader,
  waterFragmentShader,
  skyVertexShader,
  skyFragmentShader
} from '@strata-game-library/shaders';

Presets Package (@strata-game-library/presets)

Pre-configured settings (requires @strata-game-library/core):

import { createTerrainPreset, TerrainBiomes } from '@strata-game-library/presets/terrain';
import { createWaterPreset, WaterTypes } from '@strata-game-library/presets/water';

Mobile Plugins

Platform-specific capabilities:

// React Native
import { useDevice, useHaptics } from '@strata-game-library/react-native-plugin';

// Capacitor (Web/iOS/Android/Electron)
import { useDevice, useInput } from '@strata-game-library/capacitor-plugin/react';

Design Principles

1. Progressive Disclosure

Start with high-level components, drop down to lower layers when needed.

2. Zero Configuration

Everything works out of the box with sensible defaults.

3. Full Customization

Every parameter is configurable when you need control.

4. Performance First

GPU-accelerated by default, mobile-optimized.

5. TypeScript Native

Full type safety with excellent IDE support.
