Fake Tube Light Shader

fakelinelight

Tried to test idea about tube lights (or “line light”), by using custom lighting in shader,
you could sample the light several times from different positions/angles,
so that it looks like the light is not just a single point. (not really working here properly yet, but kind of gives the effect, so it might be possible)

Source: *Light direction is animated in shader to show the effect

If you want real Area Lights, check:
