How do I turn a CAD file into product images?

Open the studio, drop in your file, and Rendermio converts it in the browser. Pick a material, choose one of the six Looks — each sets lighting, backdrop, pose and camera together — and export. A first image takes about a minute, and no 3D experience is needed.

Which file formats can I use?

STEP, IGES, BREP, Rhino 3DM, STL, OBJ, glTF, FBX, Collada, PLY, 3MF, AMF, 3DS, VRML, VTK, USDZ and Draco. STEP, IGES and BREP are converted with a real geometry kernel (OpenCascade compiled to WebAssembly) rather than an approximation, so curved surfaces stay curved.

Is my CAD file uploaded anywhere?

No. Conversion and rendering both happen on your own machine, using your GPU through WebGL. The file never leaves the browser and nothing about it is stored on a server — which is the point for anyone working on unreleased designs under NDA. Signing in creates an account for your plan only; it gives us no access to your work.

Can it render diamonds and gemstones properly?

Yes. The Traced renderer follows light through a stone's real facet geometry with dielectric Fresnel and dispersion, rather than faking sparkle with a texture. There are 40 cuts, sixteen of them real cut geometry down to a heart, and every stone in a piece can be tuned on its own.

Does it only do jewellery?

No. The same engine renders cars, furniture, buildings and household products. Jewellery gets the ray-traced gems and measured golds; everything else gets car paint, timber, leather, cloth, stone, glass and the industrial metals. Tell the studio what your file is and it dresses it accordingly.

Still images up to 8K, export packs sized for store listings, social and print, and a 360° turntable video as WebM or MP4. Cut-out PNGs carry a transparent background for compositing, and a contact sheet labels every frame in a pack.

The browser studio is free and ad-supported: all materials, cuts and looks, 8K images and turntable video. $4 a month removes the ads. Cloud path-traced rendering is planned as a further paid tier — email rendermiostudio@gmail.com to be told when it opens.

What do I need to run it?

A current desktop browser with WebGL 2 — Chrome, Edge, Firefox or Safari. Rendering uses your graphics card, so a faster GPU means faster exports, but a normal laptop handles the catalogue designs comfortably.

Mesh formats

Render a Draco (.drc) file in your browser

Draco is Google's mesh compression — the same one inside compressed glTF files. Rendermio decodes a bare .drc in the browser and renders it, so a mesh compressed for the web can be shot as a product photo.

How Rendermio reads Draco

Accepted as .drc. A .drc file is decoded by the Draco WebAssembly decoder in the page into a single mesh, which then gets the same treatment as STL: welding, smooth normals if none are present, and a split into parts wherever the geometry is disconnected. Draco inside a glTF is handled on the glTF page; this is for the bare file.

What comes through

The mesh, decoded at full precision
Normals and UVs if they were encoded
Separate parts where disconnected

What does not

Materials — a bare .drc carries geometry only
Scene structure: one file is one mesh

Exporting Draco from your CAD program

For anything with materials or multiple objects, use a Draco-compressed .glb instead — same compression, more of the model

Draco files typically come from gltf-pipeline and gltf-transform, web asset pipelines, Google's Draco tools. Working in SolidWorks, Fusion, CATIA, Inventor or Creo? Their native files are not readable in a browser — here is what to export instead.

Then what happens

Once the file is in, the steps are the same for every format: tell the studio what the object is, and it dresses it — one click finds the stones in a ring and makes the rest gold. Pick a Look, which sets lighting, backdrop, pose and camera together. Export a listing pack up to 8K or a 360° turntable video. Everything runs on your own GPU; the file never leaves the page.

Questions

What opens a .drc file?

Very little, which is why this page exists. Rendermio decodes it in the browser with the Draco WebAssembly decoder and renders the mesh with real materials.

Is a bare .drc the same as Draco in a GLB?

Same compression, different wrapper. The GLB also carries materials and multiple objects; the bare .drc is one mesh. Both are supported.

Does decoding happen on a server?

No. The Draco decoder runs in your browser, like everything else in Rendermio. The file is never uploaded.
