i need to create images of 2d perspective views of 3d models. I was thinking of using opengl or vtk but i don't know how to achieve this with either of them.

Notes:

  • I need to create multiple views and taking screenshot is not feasible. I want to change the "camera matrix" in order to create views and output images.
  • The Os i'm working with is Linux.
  • 1. Do you have the required CAD software or do you need a solution that does not require CAD software? 2. Do you have 100s of files to make views of where this should be an automated process? 3. Can you just open the CAD software and take a screenshot of each 2d view you want? 4. Which OS do you need this for? Be specific. – Bulrush Sep 11 at 10:58

One of the many options you have would be to use Onshape, a free web-based CAD program. It supports import of various 3D models, including STL files.

A feature in Onshape is the ability to create orthographic drawings from the original model. You have the ability to create the drawing with "standard" front, right and top views as well as the isometric rendering, or you can customize the views you wish to include.

The drawing below began as an STL file, created in a flash with Tinkercad (not my choice) and imported to Onshape.

  • Onshape is free only under certain circumstances. For one, your data if fully exposed so the free version is essentially useless for commercial applications where confidentiality is necessary. – Eric Shain Sep 11 at 19:56
  • Yes, for sensitive documents, one would want to import the model, create and download the drawing, then delete the files. – fred_dot_u Sep 11 at 20:45
  • If this were to be for a patent illustration, I’d avoid even a transient upload as it could conceivably be considered publication. – Eric Shain Sep 12 at 3:55
