Glow

Does anyone have an example of generating a glow-like effect around lines or text in Nodebox3?

Hi Kurtzwrk,

I gave it a try. Example attached.

I am not entirely happy with the result - it's a bit crude. But the technique is simple and could serve as a start to a more sophisticated solution.

The glow subnetwork takes a shape and makes 100 copies, ranging from 50% scale to 150% scale. The glow color has a very low alpha - almost transparent - so that when they are superimposed they create a fading glow effect. The 100% scale copy is drawn opaquely on top of the rest.

You can adjust the range to create a larger or smaller glow spread, and adjust the colorize nodes to change hues.

Let me know if this helps. If someone out there has a better solution, please share it!
