## What it is
Curv is a pure functional programming language for creating 2D and 3D art using mathematics, built on Function Representation (F-Rep) with GPU-accelerated rendering. It doubles as a geometric modelling tool supporting full colour, animation, and watertight mesh export (STL, OBJ, X3D) for 3D printing.

## Use cases
- create generative art with a functional programming language
- model 3D shapes using signed distance fields and CSG
- export watertight meshes for 3D printing
- reproduce shadertoy-style graphics with simple programs
- teach math through visual creative coding
- make animated full-colour 2D and 3D models

## When to choose
- you want a beginner-friendly functional language for mathematical art
- you need F-Rep or SDF-based modelling with GPU rendering
- you need defect-free mesh export for full-colour 3D printing
- you want to prototype shadertoy-like effects as reusable shape operators

## When to avoid
- you need a production CAD tool with precise engineering constraints
- you require a stable, mature language with long-term support
- you need a browser-only tool (web interfaces are early prototypes)
- you want imperative or object-oriented modelling workflows

## Facets
- artifact type: application
- maturity: active
- function: programming-language, graphics, simulation, gui
- domain: graphics, programming-languages, artificial-intelligence
- platform: windows, cpp
