Render a 2d dotted circle around an object

Hello there,

I want to make an object that will render as a 2d circle from a camera, as in the following image:

How do I do this without postprocessing? I would like to animate the circle…

Thank you very much!


You can either modell it by hand (using an array and curve modifier) or look into the freestyle branch, where you have various linestyle options.

Thank you very much. I think I will go for the array / curve modifier.

You could also do this with material transparency and a circle, or a circle and the Mask modifier.
