Lab Engine — Rev. 02 — Runs entirely in your browser

From STL to answer, in one tab.

Two focused tools for the moment right after a 3D model is done and you need it to do something — become a hologram-ready video, or tell you whether the geometry is aerodynamically sane before you build it.

No installs, no accounts, nothing uploaded anywhere. Drop in an STL and the file never leaves your machine.

2 tools 0 installs 0 uploads — all client-side

Tool 01 — Display

STL → Holofan Video

Load a 3D model, light it, color it, animate it, and export a seamless looping video sized for hologram-fan displays — right from the browser, no render farm.

Multi-object scenes with per-part coloring and manual paint
Bloom, rim light, and a working material system
Direct MP4/WebM export at your target resolution

Tool 02 — Screening

STL-CFD Lite

Drop in a rocket geometry and get a fast aerodynamic screening pass — surface flow, drag estimate, stability read — before committing to a full CFD run.

Instant surface flow visualization, no mesh wrangling
Printable PDF summary for build logs and pre-flight checks
Zero setup — no OpenFOAM, no cluster, no wait

Free to use

Both tools are free — no account, nothing uploaded, run entirely in your browser. If one saves you time, a donation goes straight toward keeping them running and building the next one.
