Module engine 

Backend-agnostic animation engine (ported from thinking-orbs).

Structs

Dot

A projected, depth-shaded disk.

Frame

Frame geometry produced by a mode painter (backend-agnostic).

Line

A stroked edge between two projected points (the connecting web).

ModeOpts

Free-form numeric knobs for mode painters (mirrors upstream ModeOpts).

Proj

Spin + tilt + orthographic projection, precomputed once per frame.

Constants

MAX_ICON_D

MAX_MORPH_DOTS

Max dots the Morph painter will emit after icon_d is applied.

MAX_NODE_N

MAX_SIZE

MIN_SIZE

Logical size (px) accepted by crate::orbs::engine::draw_mode_into.

Functions

base_profile

Base (fine) profiles per mode, before preset multipliers.

draw_mode

Paint one frame for the given mode into a fresh Frame.

draw_mode_into

Paint one frame for the given mode into an existing Frame, reusing its buffers.

make_proj

Shared spin + tilt + orthographic projection.

sanitize_mode_opts

Return a safe copy of opts with every count-like / radius-like knob finite and within the hard ceilings above.

sanitize_size

Clamp the logical paint size in pixels.

scale_counts

Scale total dot density. 2-D lattices (rings × dots-per-ring) take √scale each side so the TOTAL scales by scale. Flat lists scale linearly.

scale_radii

Scale every key that sets a dot’s rendered radius.

sort_dots

Z-sort far→near so nearer dots paint over farther ones.
