3-d ripple punch
Okay this is a few parts of a question.. Because I am trying to achieve a very particular effect and it’s just not working…
What Im doing is trying to track a glow to the movement of a charectors fist as he punches someone, I would like the glow to be vibrating vie a sphereized ripple… then I am trying to ripple the enviroment outwards from the fist travling in a direction perpendicular to the active camera. So it would look like a sound wave veiwed from the side.. I would also like to add depth to the ripple by adding a moving shadow extending from the peak of each ripple to the base of each crest so that it looks like the light playing on the ripple (forcewave of the punch) is being acted on by the movement of the ripple itself…
Now how the h e double hockey sticks should I acheive all this?
I originally tryed creating a 3 pale yellow solid lowering the opacity to about 15 % and tunringin it perpendicular to the camer and then adding a ripple and pulling it in the direction I wanted with a mesh dsistortionb effect… it didn’t look right…(With this effect, think Dragon Ball Z or the flying fight in the matrix revolutions. . . if that helps)
Thanks… in advance…

I would try normal maps to use as displacement maps in AE. So in a 3D app create a surface, use a wave distortion (usually with the others like bend, twist, It may be called “sine”). So you have a true 3D surface that is rippling. Match this perspective to your video. If your video is moving, then do a 3D track on it and use that track cam in your 3D app. Once you have this rippled surface to your liking, Some apps (like C4D 9.5) will create a normal map from the ripple displacement. This is to convert true 3D geometry into a map that can later be used as a texture. You see this in modern video games so things look like they have depth when it’s just a normal map.
Import this normal map into AE. You’ll see that the normal map uses the 3 color channels to define the 3D surface, Use these colors in the AE displacement map effect to create the ripple to your liking. This should give you huge flexibilty and a true 3D look.
If your 3D app of choice doesn’t do normal maps, you can try lighting the surface in 3D with a green light from one angle, then a red light from the reverse angle so that the colors compliment each other to define the surface.

This may be true, but 2.5-D is there to fake stuff that is do able only in 3-d … So there has to be a way to fake it…

Use wave world (with a moving wave generator) to create a movie to use as a displacement map?
-
IS WAVE WORLD A INDY APPLICATION OR A PART OF AFTER EFFECTS? OR A PLUG IN IF IT IS A INDY OR A PLUG IN WHERE CAN i DOWN LOAD IT..
((SORRY ABOUT THE CAPS i AM RENDERING AND IT GOES FASTER IF YOU HAVE CAPS LOCK ON BECAUSE IT DOESN’T…. WELL …. RELIZING WHO IS TALKING TO … SO SORRY ABOUT THE CAPS))

I did the exact same thing recently for a video where my main character flew right into the sky and I wanted a round ripple on the ground when he blast off. Just like Neo 🙂
No need for a 3D Application! Come on!
You just go into Render > Ellipse. You animate the weight and the height from 0 to 900 X 900 (or whatever). After that, you procompose it, and you make it as a displacement map.
Put some Motion Blur if you like and ajust to your taste.
Or, like Steve Roberts, Wave World could help too, especially if you want your waves to have 3D volume.
Thinking of it, as a fan of Dragon Ball and the Matrix, the style of combats are very similar. Maybe because the both were created by chineses.
Hope that helped!

Not dicounting the quality of your result, but it comes down to a matter of tastes and quality. When the punch ripple was made in Matrix, I’m sure it was a combination of many diciplines including 3D. Usually for such high quality work, there is a team that works on it for months to perfect the image to the highest standards. Especially if his image is moving, you’ll want a good track in 3D.
So there is no absolute. I think if the Matrix VFX team could do the exact effect from the film with an ellipse and displacement map, there would be millions of dollars saved. So it’s great we all throw our 2 cents in, but I wouldn’t go so far as to say the effect can be done to the final standards with one path only needed.

” … it all depends how realistic you want it to be.” 🙂

P.S. You can minimize AE so you don’t need Caps Lock on.

BTW, Wave World is part of AE.

Download Wave World here.
Chris, I knew, by the time the words “No need for a 3D application!” had been written there was going to be reactions 😉 Thx for your responding nicely, I fully understand your point and you made a good one.
Cheers.

Thank ever so much, It all helps, it doesn’t have to be very realistic it is for a campy film about demons and angels fighting.. I mean I am going to make their fists glow. and the guy is only paying me 1K for a features worth of work. But I would like it to look as sweet as possable..
Thanks,
Really you can minimize, AE while rendering? Hmmm? so the frame wont feel the need to refresh and I won’t have to be typing in caps.. my chat buddies will thank you for that…
