TerraMath

Overview

Version 1.3.0 introduces significant improvements to the TerraMath mod, including performance optimizations, new mathematical capabilities, enhanced error handling, and server compatibility.

What's New

New Commands

• Added /terramath [info|formula|settings] command to display information about the world settings, current formula, or configuration settings.
• Added /formula command that outputs the current terrain generation formula in a copyable format for easy sharing.

Mathematical Capabilities

Constants Support: Added support for mathematical constants

• Basic constants: pi (π), e, phi (φ)
• Advanced constants: zeta3 (ζ3), catalan (K), alpha (α), delta (δ), omega (Ω)
• All constants can be referenced by both symbol and name (e.g., π or pi)

New Mathematical Functions

• atan2(x,y) - Two-argument inverse tangent
• root(x,n) - Calculate nth root of x
• gcd(x,y) - Greatest common divisor
• lcm(x,y) - Least common multiple
• modi(x,y) - Modular inverse
• and even more...

Optimized Random Number Generation

• rand() - Generate random number between 0 and 1
• randnormal(mean,stdev) - Generate number from normal distribution
• randrange(min,max) - Generate random number in specified range

Noise Functions

• perlin(x,y,z) - Perlin noise generator
• simplex(x,y,z) - Simplex noise generator
• normal(x,y,z) - Normal noise generator
• blended(x,y,z) - Blended noise (combines multiple types)
• octaved(x,z,octaves,persistence) - Octaved noise for more natural terrain

Technical Improvements

• Formula Compilation: Formulas are now compiled into Java code using Janino rather than represented as node objects, significantly improving performance
• Error Handling: Added detailed syntax error handling with user-friendly notifications
• Dedicated Server Compatibility: Improved support for dedicated servers
  • Server configuration file handling
  • Fixed loading of noise settings from world data
  • Added notification system for corrupted formulas

User Experience

• New config system
• Larger formula input field (up to 1024 characters)
• Added tooltip for long error messages
• Updated config translations for multiple languages
• Added modmenu description translation support

Bug Fixes

• Fixed function shadowing when one name is a prefix of another
• Prevented null exceptions caused by integer division by zero
• Fixed checkbox state persistence
• Improved formula validation and error handling
• Fixed noise settings loading from world data
• Resolved several UI positioning issues

Developer Changes

• Reorganized math package into specialized subpackages (parser, formula, functions)
• Reorganized utility functions into subpackages
• Replaced HashMap with ConcurrentHashMap to prevent concurrency issues
• Added terrain information command for debugging
• Code cleanup and performance improvements throughout

Removed Features

• Removed dependency on Architectury API
• Removed redundant 1.5x multiplier from the base formula

Coming Soon

• More formula examples in the community Discord
• Additional noise types and combinations
• Further performance optimizations for complex formulas
