Asset Matrix

Procedural sealife archetypes for the My Little Horizon scene. Each cell is a unique random instance — refresh to re-roll. New archetypes ship here first, then port to the live scene.

Coral · Branching

Recursive bezier branches with bioluminescent tips. 2–4 root branches, 1–2 levels of recursion, ±0.30–0.55 rad split angle. Tips glow softly with a slow pulse and rare near-fade-out.

Coral · Anemone

Short rounded stump body with 28–40 tentacles distributed around an oblique top rim, forming a soft glowing collar instead of a starburst from a single point. Each tentacle is a single quadraticCurveTo stroke from its rim base out and slightly up, with small per-tentacle length, pitch, curl, and sway-phase variation. Tentacles are paint-sorted by tip canvas-y so back-of-rim tentacles draw first and front-of-rim tentacles overlap onto the body — this turns the silhouette into a halo rather than a fan. Tip bulbs are small and dim by design so the crown reads as continuous glow, not dot-spotted.

Coral · Fan

Single base point fanning into 9–13 root branches across ~110° spread, each recursively splitting 3 levels with asymmetric per-step angle and length jitter. Line widths and alpha taper from base (denser, thicker) to tips (sparser, thinner). No trunk, no fills — pure recursive line illustration like a transparent leaf made of coral branches.

Coral · Plate / Table

Low, sideways-spreading colony of 1–4 irregular plates (biased to 2–3): one main plate plus 1–3 smaller side plates placed around a shared root, with enforced minimum horizontal separation between centers so plates never line up vertically. Plates are oblique discs with rims warped by 3-band radial sin noise — clearly blobby, not ellipses. Vertical separation is small (total colony height ≈ 0.2–0.4× colony radius), so the silhouette reads as a stepped low mound or shelf, never a tower. Side plates may slightly intersect the main plate. Thickness shows as a dim band beneath each top face — no hard rim outline. Brightness comes from a soft top-surface bloom; polyps glow additively with a mild rim bias and uniform random angles (no spiral).

Coral · Finger / Pillar

Cluster of 4–7 solid upright cylindrical pillars, each a thick stroke with round caps (capsule shape). Per-finger height (55–100%), width (75–125%), hue shift (±20°), curl direction, and sway phase create an organic cluster. Bright bulbous tip on each finger with a tiny brighter core. Distinct from branching coral (which is lacy strokes) by being chunky solid bodies — like an underwater rock-finger formation.

Coral · Brain / Soft

Single low rounded dome (wider than tall, 0.55–0.78 height-to-half-width ratio) with a labyrinthine surface ridge pattern. The dome silhouette is warped by 3-band radial sin noise so it reads as a rounded boulder, not a clean half-ellipse. 11–16 surface ridges run across the dome, each a meandering path built from two summed sin frequencies (slow drift + sharp inflections) drawn additively in hueTip and clipped to the dome silhouette so they narrow naturally near the top. No stem, no sway — brain coral is rigid, with only a very slow gentle pulse.
