Perlin Noise

• Perlin Nose 1D/2D/3D generates perlin noise
  • Input
    • X, Y, Z: Position
    • Frequency: Frequency
    • Amplitude: Scale factor of generated noise
  • Output
    • Out: Generated Noise [0.0, 1.0 * Amplitude]
• Octave Perlin Noise 1D/2D/3D generates perlin noise accumulated from different octaves
  • Each octave generates a noise whose frequency is 2^(octave-1) and amplitude is persistence^(octave-1)
  • Input
    • X, Y, Z: Position
    • Octave: Number of octaves
    • Persistence: Base of amplitude
  • Output
    • Out: Generated Noise [0.0, 1.0 * Amplitude * Octave]
• Accumulated Perlin Noise 1D/2D/3D generates perlin noise accumulated from different frequencies and amplitudes
  • Input
    • Frequencies: Frequencies
    • Amplitudes: Scale factors of generated noise
    • X, Y, Z: Position
  • Output
    • Out: Generated Noise [0.0, 1.0 * Sum(Amplitudes)]

Application of Perlin Noise

• Generate Terrain
