VR Plotter

A webapp that plots multivariable functions into an immersive VR environment. Enter any function of the form f(x, y) and fly around a 3D graph of it in your browser.

What it does

Type a mathematical expression in terms of x and y, hit Plot, and the app generates a VR scene populated with spheres at every (x, y, z) point on the surface. Use WASD to fly around and drag the mouse to look.

Usage

Functions are entered using JavaScript's Math object:

Math notation	Input
sin(x)	Math.sin(x)
e^x	Math.exp(x)
x²	Math.pow(x, 2)

Do not include z = — just the right-hand side expression.

Examples

Gaussian Distribution

3*Math.exp(-Math.pow(x,2)-Math.pow(y,2))

---

Parabolic Bowl

Math.pow(x,2) + Math.pow(y,2)

---

Sin(x) + Cos(y)

Math.sin(x)+Math.cos(y)

Running locally

With Docker (recommended)

docker compose up

Then open http://localhost:8080.

Without Docker

Serve the project from any PHP-enabled web server (Apache, nginx + php-fpm, or php -S localhost:8080).

Built with

• A-Frame — WebVR framework
• PHP — server-side expression injection into the scene
• Bootstrap 4
