Tangent based blur

Hi everyone.

I'm trying to make an effect and I can't get the outer borders of several lines to create a blur effect taking into account the direction of the line.
With the directional blur or directional distance nodes I can apply a blur but with a global direction.
Is there a way to make each of the segments have a blur based on its own tangent?

Thanks

Hey Procedural_3d,

I really like the idea of a tangent based blur, I'll look into it and probably make one.

But there are some questions.

How should the blur know, which tangent to use, there are 4 sides.
how do you create this pattern? Splines?
Do you want only one direction, the direction of the Path?

All the best Marco

Hi Marco, thank you for your interest. I will try to answer your questions.

1.- I guess you could proceed like in the flood fill node, creating segments and analyzing each of them separately.

2.- My workflow is create a spline and then delete some parts with some noise. So at this step I have no spline info to work with.

3.- My idea is only to blur the tips of each segment not in wide but with the direction of the last parts. I guess you can measure the curvature ( I am thinking like in Houdini, sorry ).

Thanks in advance
