Create a complete multi-object animated video from scratch.

This is a general-purpose procedural animation engine.

Multiple objects can exist in the same scene.

Supported object types: circle rectangle line triangle ellipse text

Every object can independently animate: x y rotation scale opacity size

Animation values can use expressions involving: t sin() cos() tan() abs() sqrt() pi()

Example:

{ "type": "circle", "x": { "expression": "300 + 100sin(t4)" }, "y": 300, "radius": 40, "color": "#ffffff" }

Objects are rendered in list order. Later objects appear on top of earlier objects.

This allows complex scenes such as: stick figures cars rockets planets bouncing balls animated logos simple characters UI animations kinetic typography

Create a complete animated stick-figure running scene.

Includes: head body left arm right arm left leg right leg ground shadow

The complete character is created from multiple independently animated shapes.
