Say goodbye to "Blueprint Spaghetti"! The Universal Math Expression & Geographic Translator API is a lightweight, high-performance C++ and Blueprint plugin designed to bridge the gap between external mathematical notation, real-world GIS coordinates, and Unreal Engine.
Whether developing educational software, scientific tools, GIS globe applications, IoT telemetry dashboards, or gameplay math parsers, this plugin converts popular external formula formats into native FMath syntax and provides ready-to-use spherical 3D coordinate transformation.

KEY FEATURES
Multi-Format & Case-Insensitive Math Parsing
Stop chaining dozens of Sin, Cos, Divide, and Square Root nodes across your graph. The parser automatically normalizes operators, Greek variables, fractions, and case-insensitive function names across major environments:
• LaTeX / TeX: \frac{\sin(x)}{\cos(y)} ➔ ((FMath::Sin(x)) / (FMath::Cos(y)))
• LibreOffice Math / OpenOffice (StarMath): { sin(x) } over { cos(y) } ➔ ((FMath::Sin(x)) / (FMath::Cos(y)))
• Exponents & Powers: Automatically converts bracketed exponents (e.g., x^{y} or (a+b)^{3}) into FMath::Pow(x, (y))
• Excel / Spreadsheets: SQRT(x) + POWER(y, 2) / PI() ➔ FMath::Sqrt(x) + FMath::Pow(y, 2) + 3.14159265f
• Matlab / Octave: power(x, 2) + log10(y) ➔ FMath::Pow(x, 2) + FMath::Logx(10.0f, y)
• Standard Plain Text: sin(x) + sqrt(y) ➔ FMath::Sin(x) + FMath::Sqrt(y)
• Greek Variable Cleanup: Automatically parses \theta, \phi, \alpha, \beta, \gamma, and \lambda into standard variable names.
Geographic & Sphere Translator (GIS & IoT Ready)
Converting standard right-handed spherical math coordinates to Unreal's left-handed coordinate system is handled automatically. The built-in Convert Lat Long To Local Vector node handles angle-to-radian conversion and X-Forward / Y-Right / Z-Up axis alignment under the hood.
• Input real-world Latitude, Longitude, Globe Radius, and Altitude to get accurate 3D world vectors (X, Y, Z) for spawning markers, aircraft, or IoT telemetry points on 3D globes.
Pure C++ Blueprint Nodes
• Pure execution nodes (BlueprintPure) with zero Garbage Collection (GC) overhead.
• Drop-in .uplugin architecture with zero third-party dependencies.
Showcase Note: The 3D globe dashboard screenshots demonstrate an interactive application built using the included Convert Lat Long To Local Vector node. This package contains the underlying C++ / Blueprint Math & GIS Translation API.
QUICK START GUIDE
1. Enable Plugin
Navigate to Edit > Plugins.
Search for "Math Translator", check Enabled, and restart the editor.
2. Translate Math String to UE (Blueprint)
In any Blueprint Event Graph, right-click and add the Translate Math Expression node.
Provide your mathematical string into the Expression Input pin:
LaTeX: \frac{\sin(x)}{\cos(y)}
MATLAB: power(x, 2) + log10(y)
Excel: SQRT(x) + POWER(y, 2)
The node automatically strips Greek formatting (\theta, \phi, etc.) and outputs native Unreal syntax: FMath::Pow(x, 2) + FMath::Logx(10.0f, y).
Route the output string to a Print String node or your custom evaluator.
3. Convert GPS Coordinates to 3D Local Vectors
In your Blueprint, add the Convert Lat Long To Local Vector node.
Connect the coordinate and sphere parameters:
Latitude: 37.7749
Longitude: -122.4194
Globe Radius: 6371.0
Altitude: 100.0
Connect the output Vector (X, Y, Z) into Set Actor Location or Spawn Actor to position assets in Unreal's left-handed coordinate system.
