This is an interesting image effect or something else

Hey guys, this is a very interesting image effect, at least to me.

How could one make (looks like the verticies) are stretching not a simple warp, because if you look at all the walls sometimes you see the tiling of the triangle getting stretched.

How could something like that be done?
(To follow a projectile).

is it a mere camera warp, or is it something more involved dealing with complex mesh manipulation?

I think you’d need a geometry shader for walls.

It’s been about 7 months sense I worked with Shaders lol.
I stopped after i got my hands on Unity 5 as it seems different than what I used to do with 4X.

So oh boy, got a lot of studying to do, because I wanna make a gun like this for my game lol.

Oh wow, I wonder how that was made (I mean just how hard it was.) Because that’s really awesome :).
