📐 Coordinate Converter

Coordinate Converter

Convert between Cartesian, Cylindrical and Spherical Coordinate Systems using Flutter.

---

✨ Overview

Coordinate Converter is a Flutter application that converts points between the three most common 3D coordinate systems.

The application performs all mathematical calculations manually without using external conversion libraries.

Supported systems:

• Cartesian Coordinates
• Cylindrical Coordinates
• Spherical Coordinates

🧮 Mathematical Formulas

Cartesian → Spherical

r = √(x² + y² + z²)

θ = arccos(z / r)

φ = atan2(y, x)

---

Cartesian → Cylindrical

ρ = √(x² + y²)

φ = atan2(y, x)

z = z

---

Cylindrical → Cartesian

x = ρ cosφ

y = ρ sinφ

z = z

---

Cylindrical → Spherical

r = √(ρ² + z²)

θ = atan2(ρ, z)

φ = φ

---

Spherical → Cartesian

x = r sinθ cosφ

y = r sinθ sinφ

z = r cosθ

---

Spherical → Cylindrical

ρ = r sinθ

φ = φ

z = r cosθ
