Spline constant thickness in camera
show user profile  magarlick
Dear all

Does anybody know how to render a spline such that its thickness along its entire length is constant, regardless of distance from the camera? I imagine a float script controller assigned to the Thickness in curves would do it but don't know the syntax.

Many thanks.

M.

in editable spline, in the mod section go check enable in render and enable in viewport then you can set the thickness.

I think what he's asking is, how to make it appear same pixel width on render, regardless of distance.

What about cheating and using bloom with a hard falloff? Just a random idea, but could maybe work.

@ Magarlick Which renderer? Maybe a wireframe material assigned to it, with pixel width adjustment should do the job. Not the most elegant solution. But it works.

The question is a little vague.

Do you want a constant thickness along the whole spline that would depend on the distance between the camera and, say, the spline's pivot, or closest point, or bounding box center, etc?
Or do you also want the thickness to vary along the spline, based on the distance of every part of the spline to the camera?

There are solutions for both but they're different.

Oh forcing pixel perspective for distance.
I'm sure writing a script would be the best bet, but since I don't know how I would do what hefst said and bloom it, or convert and modify it.

Is it possible to change camera to orthographic settings? That would keep the thickness constant? I pose this as a question because I've never done it.

Garp, I want the thickness of the spine to vary along its length, so that the entire spline has a constant thickness regardless of distance from the camera. In other words, the second of your two choices. Apologies for not being clearer and thanks to you (and others) for responding.
