Module texture 

Texture synthesis module (Layer 2: The Flesh)

This module implements deterministic texture synthesis using PPF-based noise generation. Instead of storing high-entropy texture pixels, we store compact region descriptors and synthesize the texture on-the-fly during decoding.

The Cheat

Standard codecs spend huge amounts of bits encoding “noise” (pores on skin, grain in asphalt, leaves on trees). We don’t store the pixels - we store a synthesizer config and generate the texture deterministically.

Data Structure

A Region stores compact texture synthesis parameters instead of raw pixels:

• Position and size (x, y, w, h)
• Deterministic noise seed
• Chaos level (number of octaves 1-8)
• Scale (base frequency log₂)
• Persistence (amplitude decay 0-255 → 0.0-1.0)
• Noise type (fBm, turbulence, ridged, etc.)
• Base color (RGB)
• Amplitude (noise amplitude 0-255)
