Rapier Physics
A Rust-based physics engine compiled to WebAssembly — used inside React Three Fiber via @react-three/rapier — for rigid-body, collision, and constraint simulation in browser 3D scenes. VULK uses Rapier when a project needs interactive physics.
Rapier Physics
Rapier is a fast, deterministic 2D and 3D physics engine written in Rust by the Dimforge team and compiled to WebAssembly for the browser. It handles rigid bodies, colliders, joints, character controllers, and continuous collision detection at simulation rates that hit 60 fps on consumer hardware with hundreds of bodies. The React binding @react-three/rapier exposes Rapier as JSX components — <Physics>, <RigidBody>, <CuboidCollider> — that drop straight into a React Three Fiber scene.
VULK wires Rapier into any generation that mentions physics, drag-and-drop 3D, falling objects, or interactive WebGL playgrounds. The agent imports @react-three/rapier, wraps the canvas with <Physics gravity={[0, -9.81, 0]}>, and lifts each interactive mesh into a <RigidBody>. For static obstacles, <RigidBody type="fixed"> with a matching collider is emitted automatically.
GLSL Shader (browser)
A short program written in GLSL (OpenGL Shading Language) that runs on the GPU per-vertex or per-pixel inside a browser WebGL canvas. Used for generative backgrounds, ripples, gradients, and post-processing.
Cloudflare R2
Cloudflare's S3-compatible object storage with zero egress fees. VULK uses R2 to store generated assets (videos, 3D models, images, exported ZIPs) and serve them globally from the Cloudflare edge.
