Logarithmic Spiral Biome

A Minecraft mod for Fabric and NeoForge that generates Overworld and Nether biomes in a mathematical logarithmic spiral pattern.

---

Overview

Unlike standard Minecraft world generation which relies on random multi-noise blobs, Logarithmic Spiral Biome distributes biomes along continuous logarithmic spiral arms ($r = a \cdot e^{b\theta}$) emanating outward from the world origin point (X=0, Z=0).

Each biome occupies a curving radial sector that expands progressively as you travel farther from spawn, creating a structured, navigable, and aesthetically striking world.

Features

Core World Generation

• Logarithmic Spiral Preset: Select the Logarithmic Spiral world type when creating a new world.
• Deterministic Biome Distribution: Biomes are mapped to spiral sectors centered at coordinates 0, 0.

Added in v1.1.1

• Spawn Elevation Slider:
  • Eliminates water submergence around the spawn point by raising terrain above sea level (Y=64–67).
  • Configurable in the customization screen and config: OFF or radius from 10m to 300m (step: 10m).
  • Fully optimized for fast, safe chunk generation.
• Nether Terrain Style Option:
  • Choose between two generation styles for the Nether:
    • Overworld-like (Gentle): Generates gentle, traversable rolling surface hills while preserving the bedrock roof ceiling.
    • Vanilla: Standard cavernous maze generation.
• Multiloader Streamlining: Focused support on Fabric and NeoForge.

Added in v1.1.0

• The Nether Dimension Support:
  • Nether biomes generate in a logarithmic spiral layout.
  • Independent toggles for enabling/disabling Overworld and Nether spiral generation.
• In-Game Customization Screen:
  • Accessible via the Customize button on the world creation screen.
  • Real-Time 2D Map Preview: Interactive color-coded preview of the spiral biome layout with chunk grid overlay.
  • Preset Styles: Choose from tuned presets (Standard, Large, Dense, Tight, Custom).
  • Fine-Tuning Sliders: Adjust scale (initial radius) and growth rate (arm expansion speed).
• Boundary Divider Blocks & Wall Height:
  • Optional physical boundary walls mark borders between adjacent spiral arms.
  • Searchable block picker for choosing any block as dividers.
  • Adjustable wall height from flat floor paving (0) up to 5-block tall walls.
• Biome Mod Compatibility:
  • Compatible with major world generation and biome mods (Terralith, Incendium, Biomes O' Plenty, etc.).
