How to create a constant width wireframe shader?

[magneto]

Hi,

 

I made a simple shader using the Wireframe VOP which works fine but I want it to be constant width when rendered so it looks as if the wireframe has a fixed width rather than looking thinner/thicker because of perspective.

 

Can this be done in a shader? If so, how can I do this?

 

 

Thanks

You mean like this?

Thanks Edward. No I mean something like this where the lines of a model looks the same:

 

 

as opposed to this where the lines have different width based on the camera perspective:

 

 

I actually needed this for curves but then wondered how one would actually do this for a surface.

Thanks that's interesting. Is this actually fixed width? I couldn't tell, so I think it's good.

 

But I am still looking for a shader solution as that's what I am trying to learn
