So i was playing alien isolation, and the game has really good looking lens flares where you can see the shape of the glowing object in the flare. It's done by overlaying the view with a blurred and flipped image of itself with scale-misaligned rgb channels.
Here's a photoshoped spaceengine screenshot with the effect:


and the flare by itself:


This would look nice in motion and might be feasible since spaceengine already uses a blurred image on top of itself for the bloom effect. What do you folks think?

I messed with ReShade and it actually does have something similar to this, it just lacks gaussian blur so it can look really bad when looking at giant stars. Otherwise, I would definitely use it.

Someone putted on this forum an ultrarealistic flare engine that was been developed based on that idea. I can't find the post because It's probably erased. But the video was quite spectacular. This idea looks good if well performed smile

If done a little research and found two very interesting researches on how to create physically based lens flares for computer graphics. Space Engine could be majestic (yes, even more xD)
Paper 1
Paper 2

This is called pseudo lens flares. This could be easy to implement, but we have to do something with bright point sources like distant sun. If it being one pixel size, the flare may blink.

Yes!!! this is just what I was searching in the forum smile

I'm glad to read that this is relatively simple to implement. biggrin

Was thinking of this method too, the only problem is that you'd need an extra "light sources" only pass to feed it into the Lens Flare pass; or you need to work with float values that are not clamped to [0, 1]. That way artifacts can be avoided.
Also such a lens flare would need a several pixel wide source, so there might be a need to visually increase the source size (like a texture that is only several pixels wide that would help in those situations).
