3D Graphing Calculator

Your equations,
rendered in 3D.

The GPU-accelerated graphing calculator for dynamics, differential equations, and quantum mechanics. Write LaTeX, explore interactively.

Features

Built for real mathematics

Everything you need to visualize, explore, and understand.

Real-time 3D rendering

GPU-accelerated WebGL with adaptive meshing. Complex surfaces, vector fields, and parametric plots at 60 fps.

LaTeX-native input

Write equations the way you write them on paper. Full LaTeX support — no proprietary syntax to learn.

Differential equations

Direction fields, phase portraits, and solution curves. Watch ODE systems evolve from initial conditions in real time.

Interactive parameters

Connect sliders to any variable. Drag to deform surfaces, shift equilibria, or sweep through parameter space.

Vector fields & flows

3D vector field visualization with flow lines and streamlines. See how forces shape trajectories through space.

AI-powered

Describe what you want to plot in plain English. The AI assistant builds the equation sheet and renders it for you.

For students

Designed for the classroom

From the lecture hall to the problem set — Pendulum speaks the language of your coursework.

01

Dynamics

  • Phase portraits
  • Coupled oscillators
  • Lagrangian mechanics
  • Multi-body systems

From simple harmonic motion to chaotic double pendulums. See the motion, not just the algebra.

02

Ordinary Differential Equations

  • Direction fields
  • Stability analysis
  • Bifurcation
  • Solution families

Plot families of solutions, explore equilibria, and build intuition for qualitative behavior.

03

Quantum Mechanics

  • Wavefunctions
  • Probability densities
  • Spherical harmonics
  • Orbitals

Visualize what the textbook can only describe. 3D probability clouds and wavefunctions from the equations themselves.
