cf24b62c44 fix(viewer): UI flicker on camera move from interactive overlays + dirty-mark leaks (#401)
* chore: sync bun.lock with 0.9.1 workspace versions

* fix(viewer): stop interactive overlays from starving frames and flickering the UI

Every interactive item mounted a drei <Html occlude> overlay
unconditionally — invisible (opacity 0) when no zone was selected, but
still alive. With `occlude` as a bare boolean, drei raycasts the entire
scene per overlay on every camera-move frame, and rewrites each
element's z-index while toggling display when the occlusion flips. On
scenes with hundreds of interactive items (recessed lights, ceiling
fans) this starved the frame budget and made the whole DOM UI blink
during camera moves while the WebGPU canvas stayed healthy.

Overlays now mount only while a zone is selected and the item sits
inside its polygon, fade in/out over 300ms (the child components stay
rendered so the exit transition can play before the <Html> unmounts),
and drop `occlude` entirely. eps=-1 works around a drei mount bug: its
mount path writes the element transform without the distanceFactor
scale, and with a static camera the eps guard never re-applies it, so
freshly mounted overlays stayed mis-scaled until the camera moved.

* feat(viewer): break down dirty nodes by kind in the perf overlay

DIRTY now reads e.g. "29 (12 wall, 9 ceiling, 8 item)" — sorted by
count, only non-zero kinds, with a "missing" bucket for dirty ids whose
node no longer exists. Makes dirty-mark leaks attributable at a glance.

* perf(core): skip dirty marks for kinds with no dirty consumer

dirtyNodes is consumed by GeometrySystem (def.geometry),
FloorElevationSystem (capabilities.floorPlaced), and the legacy
per-kind viewer systems. Site, building, level, zone, and guide match
none of those, so their marks were never cleared: they accumulated for
the whole session (every child create/delete dirties its parent),
permanently defeated every consumer's empty-set early exit each frame,
and polluted the perf overlay's DIRTY readout.

NodeDefinition gains an explicit dirtyTracking?: boolean opt-out
(default tracked — no derivable predicate exists since wall's dirty
consumption lives in the viewer while zone/guide/level declare
def.system for unrelated per-frame work). markDirty consults the
registry; the five structural kinds opt out.

Also fixes a second leak: deleteNodesAction never removed deleted ids
from the dirty set, and every consumer skips missing nodes without
clearing them, so marks on deleted nodes lived forever.

* style: replace concise-arrow forEach with for...of in deleteNodesAction

biome's useIterableCallbackReturn rejects forEach callbacks that
implicitly return a value (Set.add / clearDirty).

@pascal-app/viewer

3D viewer component for Pascal building editor.

Installation

npm install @pascal-app/viewer @pascal-app/core

Peer Dependencies

npm install react three @react-three/fiber @react-three/drei

What's Included

  • Viewer Component - WebGPU-powered 3D viewer with camera controls
  • Node Renderers - React Three Fiber components for all node types
  • Post-Processing - SSGI (ambient occlusion + global illumination), TRAA (anti-aliasing), outline effects
  • Level System - Level visibility and positioning (stacked/exploded/solo modes)
  • Wall Cutout System - Dynamic wall hiding based on camera position
  • Asset URL Helpers - CDN URL resolution for models and textures

Usage

import { Viewer, useViewer } from '@pascal-app/viewer'
import { useScene } from '@pascal-app/core'

function App() {
  return (
    <div style={{ width: '100vw', height: '100vh' }}>
      <Viewer />
    </div>
  )
}

Custom Camera Controls

import { Viewer } from '@pascal-app/viewer'
import { CameraControls } from '@react-three/drei'

function App() {
  return (
    <Viewer selectionManager="custom">
      <CameraControls />
    </Viewer>
  )
}

Viewer State

import { useViewer } from '@pascal-app/viewer'

function ViewerControls() {
  const levelMode = useViewer(s => s.levelMode)
  const setLevelMode = useViewer(s => s.setLevelMode)
  const wallMode = useViewer(s => s.wallMode)
  const setWallMode = useViewer(s => s.setWallMode)

  return (
    <div>
      <button onClick={() => setLevelMode('stacked')}>Stacked</button>
      <button onClick={() => setLevelMode('exploded')}>Exploded</button>
      <button onClick={() => setWallMode('cutaway')}>Cutaway</button>
      <button onClick={() => setWallMode('up')}>Full Height</button>
    </div>
  )
}

Asset CDN Helpers

import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'

// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'

// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)

Features

  • WebGPU Rendering - Hardware-accelerated rendering via Three.js WebGPU
  • Post-Processing - SSGI for realistic lighting, outline effects for selection
  • Level Modes - Stacked, exploded, or solo level display
  • Wall Cutaway - Automatic wall hiding for interior views
  • Camera Modes - Perspective and orthographic projection
  • Scan/Guide Support - 3D scans and 2D guide images
