[wip] matrix style bullet in bullettime

turb0n3rz

here is a work in progess

im trying to recreate the matrix air displacement effect that the bullets have when they are seen in slow motion

[this will be for still images and not for games if your wondering]

tell me how this one looks

please give feedback

is it good?
does it suck?

thanks, you wont hurt my feelings

It looks too solid at present, there's no distortion it looks more like glass or still water

turb0n3rz

agreed it does look abit solid

i might render it on a transparent layer and try to blend it or use it to distort the background a bit more subtle

turb0n3rz

i studied that scene and when i saw the bullet displacement, it did look a bit like glass

It's going to distort the background like glass, but the wave should not have any refections or surface lighting. The distortions shouldn't have too hard of an edge to it.

turb0n3rz

thats gonna be hard but i think i can achieve it

turb0n3rz

here it is with less glassyness

i just lowered the IOR a but more to make it seem more like air

i just added some objects for the stream to displace ans be more noticeable

heres more bullets and more displacement

FullSynch

Better, but now the bursts are too uniform. Each bubble would have expanded more than the next.

turb0n3rz

im still reviewing the footage and i know naturally you would think that they would expand gradually but in the footage other than the geometry expanding into and contracting, its more uniform than you would expect

i think that its due to that the VFX department thought that the bullet is soooo fast that it being viewed a speed slow enough so actually see the bullets moving, that the air displacment would be uniform because of how fast the bullet is moving, i believe you would see the same effect in high magnification scopes when shooting a high powered rifle.

correct me if im wrong

and please view the footage as well to point out somethings i missed

thanks for the feedback

i will try the gradually expanding approach as well and get back to you with a new render tomoro

here is the same round but with ripples within the ripples

i had to up the bounces because i get some blackness from refractions within refractions
