Resin

Constructive generation and manipulation of media.

What is Resin?

Resin is a Rust library for procedural generation and manipulation of media assets:

• 3D Meshes - geometry generation, primitives, indexed mesh representation
• 2D Vector Art - paths, shapes, bezier curves
• Audio - oscillators, synthesis
• Textures/Noise - Perlin, Simplex, fBm, lazy field evaluation
• Rigging - skeletons, bones, skinning, poses

Design Goals

• Procedural first - describe assets with parameters and expressions, not baked data
• Composable - small primitives that combine into complex results
• Lazy evaluation - build descriptions, evaluate on demand
• Bevy-compatible - works with bevy ecosystem without requiring it

Quick Examples

Mesh Generation

use rhizome_resin_mesh::{box_mesh, sphere};

// Unit box centered at origin
let cube = box_mesh();

// UV sphere with 32 segments, 16 rings
let ball = sphere();

Noise Fields

use rhizome_resin_core::{Field, Perlin2D, EvalContext};
use glam::Vec2;

// Lazy field - describes computation
let noise = Perlin2D::new().scale(4.0);

// Sample on demand
let ctx = EvalContext::new();
let value = noise.sample(Vec2::new(0.5, 0.5), &ctx);

Audio Oscillators

use rhizome_resin_audio::{sine, saw, freq_to_phase};

let time = 0.5;  // seconds
let freq = 440.0;  // Hz

let phase = freq_to_phase(freq, time);
let sample = sine(phase);  // -1.0 to 1.0

2D Paths

use rhizome_resin_vector::{circle, rect, star, PathBuilder};
use glam::Vec2;

let c = circle(Vec2::ZERO, 1.0);
let r = rect(Vec2::new(-1.0, -1.0), Vec2::new(1.0, 1.0));
let s = star(Vec2::ZERO, 1.0, 0.5, 5);

Skeletal Rigging

use rhizome_resin_rig::{Skeleton, Bone, Transform};
use glam::Vec3;

let mut skel = Skeleton::new();
let root = skel.add_bone(Bone::new("root")).id;
let arm = skel.add_bone(
    Bone::new("arm")
        .with_parent(root)
        .with_transform(Transform::from_translation(Vec3::Y))
).id;
