I want to extract the image from a mesh and save it as a separate image. Is that possible in openframeworks.
Depends on what you mean by an image of a mesh?
If it is to render the mesh and save an image of the result have a look at asimpExample in examples/addons/
It loads a mesh and draws it, you can then use ofSaveScreen to save an image of that.
I can’t find addons in openFrameworks/examples/, therefore, neither asimpExample…
now it is in examples/3d/3dModelLoaderExample
