🧊 WASM Viewer Performance Lab
Profile the RAPS browser viewer with live timings for cold start, parsing, GPU upload, scene fit, and memory use across both shipped fixtures and procedural scenes.
💡 Same profiler, different surface
This page uses the same load-profile event that backs the frontend checks in raps-viewer-js.
The first sample load shows cold-start cost. Every load after that shows the warm path.
npm run test:perf verifies the same metrics in Playwright.
Heavy URL fixture 409,600 triangles Loads
heavy-terrain-320.obj from the test host to exercise network, parse, and upload together. Generated giant preset 524,288 triangles Builds a synthetic OBJ in the browser for stress checks without committing a giant blob to git.
Semantic generators Pipes, buildings, and forests Creates structured scenes with fittings, slabs, walls, doors, windows, trunks, branches, and leaf masses directly in the browser.
Mixed campus preset Combined site scene Loads terrain, multiple buildings, a pipe rack, roads, and planted zones as one generated model for broader viewer checks.
