Render edge lengths ?

I’m wondering how I can show the edge lengths of objects in a render, without having to do it manually with the text tool.

I know I can display edge lengths in edit mode, but I cannot figure out how to have this rendered.

Is this even possible? (ver 2.7)

I don’t think it’s possible. You have an alternative with the Caliper Add-on :

And a video :

I don’t know if it works with 2.7 but you can give it a try.

Hey thanks for your suggestion. Though it looks like that addon is more steps than doing it manually. Oh well… I guess I’ll just have to use curves+text.

maybe opengl render and the composit it over a cycles render.
