kinetickit: deterministic 2D and 3D animation for Python

A domain-neutral engine for precise, deterministic 2D and 3D animation.

GitHub PyPI Python

kinetickit 1.0 is in beta

kinetickit 1.0.0b2 is a pre-release. The contracts in Compatibility are meant to be stable but may change between pre-releases, always with a changelog entry.

from kinetickit import Animation, Bounds2D, Point2D, Scene2D, Vec2, ease

dot = Point2D(id="dot", position=Vec2(1, 1), size=8, color="#e4572e")
scene = Scene2D(dot)
scene = scene.bind({scene.camera.ref("view"): Bounds2D(Vec2(0, 0), Vec2(10, 10))})

motion = dot.animate.position.to(Vec2(9, 9), duration=1.5, easing=ease.out_cubic)
animation = Animation(scene, motion)

animation.save("dot.svg", width=400, height=400)

Features

  • Scenes and motion

    Immutable 2D and 3D nodes, and motions that you compose with then, with_, delay, repeat, yoyo, reverse and trim.

    Scenes and motion

  • Time and easing

    Frames at exact times, easing families and cubic Bézier timing, keyframes and markers.

    Time and easing

  • Morphing and transitions

    Path, mesh and surface morphs with explicit correspondence, and scene transitions that match nodes by stable id.

    Morphing

  • 3D scenes and cameras

    Meshes, height-field surfaces, lights, and perspective or orthographic cameras with one shared projection.

    Camera geometry and projection

  • Three outputs from one scene

    Animated SVG, streamed GIF up to 1200 DPI, and self-contained interactive HTML, each checked against its capabilities before a file is written.

    Output formats

  • Typography

    Text that arrives as a neutral asset, laid out by GlyphKit from caller-provided fonts, with permission-checked font subsets embedded.

    Typography

  • Accessibility and interaction

    Roles, labels and reading order, a reduced-motion policy, and data-only interactions bound to node ids.

    Accessibility and interaction

  • Examples and adapters

    A chart from plain shapes, a plain Python object model animated through an adapter, and a lit 3D surface.

    Examples
