Modelian Features

Physics

Modelian includes a built-in physics engine. Control the size, shape and density of an object using units and watch objects interact realistically. Make an object springy and see it bounce around. Adjust the friction of a box and watch it quickly slide to a stop.

Interactive

Modelian lets you define custom interactivity. Make your program respond to mouse clicks or key presses. Prompt the user for input and change the program based on what it receives.

Programming

Modelian includes a flexible programming language. Use a large library of built-in functions for manipulating the progam. Use logical control expressions to define the flow of your program. You can even define your own variables and functions.

Design

Control the look of your program. Customize the color and appearance of your objects. Embed pictures and make them come alive in your program.

Free

Modelian is completely free. And as a web-based program, you don't even need to download any software or install any plugins. Get started with Modelian now!

Publish

Share your programs with others. Create a publish link you can send to others which they can use to view and interact with your program. Since Modelian is web-based, they won't need to download any software to view the program.
