Is there a free and easy way to view a model with its markers shown as vectors? I have assiduously avoided modeling and don't want to fall down the rabbit hole or install massive and powerful software. I just want to visualize the markers, nothing more.

Even showing the marker vectors without the model would be fine, as I can probably infer the model from context.

I think jackson wrote some code for this, but I dont think it was released...
