How to Capture 3D Mesh Screenshots with Vedo

3D mesh screenshots with Vedo is a Python how-to: load an STL, render offscreen, write a PNG. No interactive window. It is not a freehand mesh cut. It is not a Blender / Unreal list.

If you meant draw a loop and drop a piece of the mesh → 3D mesh cutter. If you meant Blender / Unreal / KeyShot → 3D visualization software. If you meant what a .vtk file is → VTK data format.

This is the 2023 PYCAD Team screenshot. Cut and screenshot are two jobs on two URLs. Cross-link, do not merge.

Install

pip install vedo

Load the STL

import vedo

mesh = vedo.load('path_to_your_file.stl')

Swap the path. Same loader as the cut post; this one never opens a window.

Offscreen render → PNG

Plotter(offscreen=True) is the point. Headless: add the mesh, show(), screenshot(). Useful in a batch or a CI job where there is no display.

plotter = vedo.Plotter(offscreen=True)
plotter.add(mesh)
plotter.show().screenshot('screenshot_path.png')

Swap the PNG path. Sibling notebooks: vedo-tutorials.

What this page is not

• Not a freehand cut. That is 3D mesh cutter.
• Not a DCC list. Blender / Unreal sit on 3D visualization software.
• Not a course, a newsletter gate, or a PYCAD product. A snippet we ran.

If a mesh render has to live inside a clinic viewer, that is the imaging piece. Case studies.
