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.

Rendermio

Formats

Every file Rendermio can render

Seventeen formats, three ways of reading them. CAD files go through a real geometry kernel and keep their curves; Rhino files come with their stone positions; mesh files are welded, smoothed and split back into parts. Pick your file for what to expect.

CAD — read by a geometry kernel

STEP.step .stpSTEP is the format every CAD program can export and the one Rendermio reads best.
IGES.iges .igsIGES is the older interchange format, and a lot of jewellery and tooling still travels as .igs.
BREP.brepBREP is OpenCascade's own native format — and OpenCascade is the kernel Rendermio runs in your browser.

Rhino

Rhino 3DM.3dm3DM is the native format of Rhino, and of the jewellery tools built on it — MatrixGold, RhinoGold, Panther.

Mesh formats

Working in SolidWorks, Fusion, CATIA or Inventor?

Their native files — sldprt / sldasm, f3d, ipt / iam, prt, catpart / catproduct and the rest — are not readable in a browser, and no web tool that claims otherwise is telling the truth. Every one of them exports STEP, which is the format Rendermio reads best. The export path for each program is here.

What people use it for

Jewellery rendering from your CAD file, in the browser — for jewellers
Listing photos from the CAD file you already have — for sellers
A 360° turntable video, from the CAD file — for product pages and social
