HTML, CSS, and the browser’s layout engine were designed to flow text, paginate articles, and keep markup accessible no matter the device. That legacy is why a plain `

` looks right on every screen, why screen readers can navigate effortlessly, and why a broken JavaScript bundle doesn’t kill your content. It’s also why the typical website still feels like a dressed-up report despite our hardware being capable of running entire game engines. Document-centric rendering gives us universality, but the trade-off is rigidity. When a designer wants kinetic layout, real physics, or truly fluid animation, the DOM’s cascading rules, reflow, and box model become constraints rather than allies. Responsive design solved screen fragmentation with breakpoints, percentages, and media queries—a brute-force approach that keeps piling rules onto an already complex system. Developers juggle three technologies at once (HTML, CSS, JavaScript) just to coax an element into the right spot, while stakeholders wonder why “make it pop” becomes a project in itself. diff --git a/docs/issues/physics-registry.md b/docs/issues/physics-registry.md new file mode 100644 index 0000000..761b807 --- /dev/null +++ b/docs/issues/physics-registry.md @@ -0,0 +1,19 @@ +# PhysicsRegistry — discovery, descriptors, and change events + +Labels: architecture, physics, registry, project:newton +Milestone: PROJECT: Newton + +## Summary +Design and implement a PhysicsRegistry that discovers DOM nodes, stores typed descriptors (type, tag, attrs, origins), emits change events on layout/resize, and serves as the single source of truth for activation/reset/inspector. + +## Acceptance Criteria +- [ ] Discovers `.cloth-enabled`, `.rigid-dynamic`, `.rigid-static` and nodes with data-phys-* or data-cloth-* attributes +- [ ] Descriptor includes: { id, tag, type, attrs (parsed), origin (rect/world), active state } +- [ ] Emits events: `registry:add`, `registry:update`, `registry:remove` with prior/next descriptors +- [ ] Diffing works: only changed fields emitted; stable ids across runs +- [ ] Inspector/activation can subscribe to the registry + +## Tests (write first) +- [ ] physicsRegistry.spec: discovery from a test DOM, descriptor diffing, events on resize +- [ ] integration: inspector or controller subscribes and receives `registry:update` + diff --git a/src/App.tsx b/src/App.tsx index 68d79bd..4648752 100644 --- a/src/App.tsx +++ b/src/App.tsx @@ -16,6 +16,8 @@ import { Select, Kbd, } from "@mantine/core" +import { PerfOverlay } from './app/PerfOverlay' +import { EventsPanel } from './app/EventsPanel' import type { DebugOverlayState } from './engine/render/DebugOverlayState' import { ClothSceneController, type PinMode } from "./lib/clothSceneController" @@ -65,6 +67,8 @@ type DebugProps = { onPinModeChange: (value: PinMode) => void onStep: () => void onReset: () => void + showPerf: boolean + onShowPerfChange: (value: boolean) => void } function DebugPalette(props: DebugProps) { @@ -102,6 +106,8 @@ function DebugPalette(props: DebugProps) { onPinModeChange, onStep, onReset, + showPerf, + onShowPerfChange, } = props // (labels kept close to Select entries) @@ -109,13 +115,16 @@ function DebugPalette(props: DebugProps) { return ( onOpenChange(false)} + onClose={() => { + onOpenChange(false) + }} position="right" size={380} withCloseButton // Keep dropdowns and overlay content inside the drawer layer withinPortal zIndex={2100} + transitionProps={{ duration: 150 }} > @@ -135,14 +144,21 @@ function DebugPalette(props: DebugProps) { onChange={(v) => v && onPresetSelect?.(v)} /> - - - Wireframe - Toggle mesh rendering as wireframe - - onWireframeChange(e.currentTarget.checked)} /> - + + + Wireframe + Preview edges of the simulated mesh (not the DOM element) + + onWireframeChange(e.currentTarget.checked)} /> + + + + Perf Overlay + Show rolling averages per subsystem + + onShowPerfChange(e.currentTarget.checked)} /> + @@ -311,6 +327,18 @@ function Demo() { const [drawSleep, setDrawSleep] = useState(false) const [drawPins, setDrawPins] = useState(false) const [pinMode, setPinMode] = useState('top') + const [showPerf, setShowPerf] = useState(false) + const [toast, setToast] = useState(null) + const [eventsOpen, setEventsOpen] = useState(false) + const prevOpen = useRef(debugOpen) + useEffect(() => { + if (prevOpen.current && !debugOpen) { + setToast('panel clothified: debug-panel') + const t = window.setTimeout(() => setToast(null), 1200) + return () => window.clearTimeout(t) + } + prevOpen.current = debugOpen + }, [debugOpen]) useEffect(() => { if (typeof window !== 'undefined') { @@ -356,6 +384,11 @@ function Demo() { setDebugOpen((open) => !open) return } + if ((event.metaKey || event.ctrlKey) && event.key.toLowerCase() === "e") { + event.preventDefault() + setEventsOpen((open) => !open) + return + } if (!realTimeRef.current && event.key === " ") { event.preventDefault() if (actionsRef.current) { @@ -551,7 +584,18 @@ function Demo() { controllerRef.current?.setSleepConfig({ velocityThreshold: 0.001, frameThreshold: 60 }) actionsRef.current?.setSleepConfig(0.001, 60) }} + showPerf={showPerf} + onShowPerfChange={setShowPerf} /> + + {toast ?
