Crate fastanim_core 

Core model for fastanim: geometry, mobject state, animations, the scene builder and the baked, seekable timeline (see docs/SPEC.md §4).

Has no Bevy dependency so it can be tested with plain cargo test.

Modules

anim

Animations (SPEC §4.4): planned once at bake time, then sampled as a pure function of progress.

axes

manim’s Axes: a coordinate system mapped onto the scene, for plotting in graph units.

color

sRGB colors that interpolate in Oklab (SPEC §4.3).

geom

Vector geometry (SPEC §4.1) and path alignment (§4.3).

mobject

Mobject state (SPEC §4.2): a plain value type that can be cloned, interpolated and snapshotted.

position

Positioning helpers (SPEC §8.3): next_to, align_to, to_edge and arrange, for anything with a bounding box that can be transformed.

svg

SVG still export, straight from a SceneState (no GPU).

timeline

Scene builder and baked, seekable timeline (SPEC §4.5).

transform_diff

TransformDiff (SPEC §7): turns an edit script between two keyed sequences of parts into choreographed animation, so unchanged parts slide, moved parts arc and only real changes fade or morph.

Structs

Point

A 2D point.

Vec2

A 2D vector.

Enums

Op

One step of an edit script.

Constants

DOWN

Unit vector down.

FRAME_HEIGHT

Frame height in scene units (manim’s).

FRAME_WIDTH

Frame width in scene units: 16:9.

LEFT

Unit vector left.

ORIGIN

The origin.

RIGHT

Unit vector right.

UP

Unit vector up (y is up).

Traits

Interpolate

Values that can be blended; lerp(a, b, 0) == a and lerp(a, b, 1) == b.
