STL to JPG: Render a 3D Model as an Image in Python

STL describes a three-dimensional object as a mesh of triangles. It is the format 3D printers and CAD tools exchange, and it contains geometry only, with no colors, materials or camera. JPG is a flat raster picture that any browser, document or catalog page can display.

The conversion produces that picture: a rendered view of the model that can be used as a thumbnail in a parts list, an illustration in a manual, an attachment in a quotation, or a preview in a web shop where visitors upload models for printing.

GroupDocs.Conversion Cloud performs the rendering, so no modeling software or graphics driver is required on the server that asks for it. Image quality and resolution are set in the request, which is how the same model produces both a small thumbnail and a large illustration.

In Python the SDK is installed with pip and the call is short enough to run inside an upload handler or a batch job. A Client ID and Secret authenticate the request, and a free trial covers the first conversions.

How do I convert an STL file to JPG?

Send the model to the conversion endpoint with JPG as the target format and a rendered image comes back. The free online converter does the same in a browser, which is convenient for checking one model before the call is added to a program.

Can the size of the image be controlled?

Resolution and quality are parameters of the conversion request, so one model can produce a small preview for a listing and a larger picture for print. Values are chosen per request, which avoids storing several copies of every model.

Are PNG and PDF available as well?

Yes. The target format is a parameter, so the same STL can be written as PNG when transparency matters or as PDF when the image belongs in a printable document. More than 153 formats are available as sources and targets.
