bbe0e2b0b5 feat(viewer): ?disable=draw — skip scene rendering for graph-only consumers (#482 )

The headless bake worker renders on SwiftShader (CPU), where per-frame
vertex/draw cost dominates the whole capture — but a bake only reads the
built scene graph; the pixels are thrown away. `?disable=draw` (same
diagnostic-param family as postFx) renders an EMPTY scene each frame
instead of the real one: useFrame systems and scene-ready keep ticking,
per-frame cost collapses to a 64x64 clear.

Rendering nothing at all does NOT work: with zero submitted frames
Chromium's no-damage scheduler throttles rAF to exactly 1Hz (measured),
starving the very systems the bake needs — hence the empty-scene draw.

Measured on the office scene (200+ items) with a real GPU: capture
45.0s -> 8.4s (settle 37.6s -> 4.5s); output equivalent to a normal
render (structural GLB diff clean; the ±13-accessor variance exists
between normal runs too). CPU-only (worker) numbers via the prod-image
container against a preview deploy.

@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
