Exact construction core
Euclidean objects are built from exact mathematical state, so visual exploration does not quietly replace the construction’s truth.
01 / Exact geometry
Exact geometry for construction, exploration, and discovery.
FluxGeo is a precision-first Euclidean geometry engine. Build constructions, inspect dependencies, and turn a mathematical idea into an editable object you can revisit.
The diagram represents a triangle with its circumcircle and Euler line. The dependent point updates as the construction changes.
02 / Product principles
A geometry instrument with a memory.
FluxGeo keeps the construction, the relationships between its objects, and the visual result in one inspectable workspace.
Dynamic dependency model
Move a defining point and dependent geometry follows. The graph makes relationships useful for discovery, not merely for display.
Syntax and reusable tools
ScriptBlock gives repeated constructions a readable form that can be edited, shared, and used as a starting point for new questions.
03 / Syntax
Describe a family. Explore the proof.
FluxGeo Syntax is a compact way to express constructions that would be tedious to repeat by hand. Keep the geometry visible while the script gives it a reusable shape.
- Readable declarations for points, sliders, and derived objects.
- Editable scripts that stay close to the geometry they create.
script Wave {
T = Slider(0, 6.28318, 0, 0.05)
for i in -20..20 {
xValue = i / 4
P_i = (xValue, sin(xValue + T))
}
}04 / Discovery engine
Watch a conjecture become a theorem.
This live construction is inspired by IMO 2014 Problem 4. As the parent triangle moves, each relation is recomputed from the construction rather than drawn as a fixed illustration.

05 / Applications
Choose the surface that fits the question.
FluxGeo is available in several forms. Each one has a distinct purpose; the web applications and native desktop build do not imply identical feature sets.
Modern web
A DOM-based experiment for fast, local-first exploration in the browser.
Open modernClassic web
The v1.4-beta WebAssembly application for the established interactive geometry workflow.
Open classicNative desktop
The downloadable desktop application for a fuller local environment and offline work.

Archive07 / Philosophy
Make the mathematics clearer, not louder.
FluxGeo is built for patient investigation: exact where it matters, inspectable when it is useful, and respectful of the work around it.
Exactness
Mathematical state stays authoritative while visual proxies make interaction immediate.
Privacy and local-first work
FluxGeo works locally. There are no analytics or advertising trackers; external providers receive data only after a visitor actively clicks a link.
Open source, commercial licensing
The project is open source for study and collaboration, with commercial licensing available for uses that need it.
