Blender Freestyle - how to make line crossings glow more than lines themselves? I'm trying to recreate the classic, vintage 1980s look of computer graphics - bright, glowing lines on dark background. However, after analyzing old computer graphics I found out that the intersections of lines glow more than the lines themselves - they turn into little glowing points. 

Is there a way to simulate this using Freestyle settings or compositor?

For example:
You can use a blur node to get this effect.
The blurred lines will overlap a bit at the intersections, making them brighter.

For example:


Create a renderlayer which only renders freestyle lines by disabling everything else in Render layers > Layer > Include:


Set the freestyle line color to white in Render layers > Freestyle Line Style:
