View Full Version : Spherize effect like Photoshop

I'm using After Effects 6.5 to create a text effect that simulates the rolling dials of a fruit machine/one armed bandit.

To get the effect of text rolling around the dial, I'd like to use the Distort->Spherize effect - in Photoshop this effect has the option to distort only in the horizontal direction, not the vertical. However in Afx this option doesn't seem to be present.

Does anyone know a good alternative way of doing this?

Thanks

You could use a displacement map, but a better solution might be to make a 3D subcomp that has the wheel animation in 3D space. Using the filter may have some strange distortions that don't look physically correct. And if you have a 2d/3d wheel spinning, you can add distortions on top of that to get it to look like it's refracting through glass/plactic. Have that wheel off center a tiny bit, and you'll get a slight wheel wobble (more realistic). A little extra work, but I think well worth it, depending on the shot of course.

Nice - thanks for your advice

I've tried using cylinder creator light to arrange the elements in the wheel/cylinder formation, however is there any way of creating a circular cylinder? ie at present the elements make up the flat sides of a polygonal cylinder ...

Then "render" it in photoshop using the batch function. Just make an action thats adds the effect and then saves and closes your document. Then go to File- Batch choose your action and select the folder with the image seq in it and hit OK. :thumbsup: Then import the seq in to Afx again..

Hi there I dont know if this might help you in yuor project, but instead of really creating the 3D wheel in a 3D application...would u like to try a 'cheat' ? try using a reverse reflected gradient like this in photoshop to achieve a cylindrical effect. Bevel it, add a metallic texture or add a reflection map as a screen mode over it...you'll definitely get a cool looking image and you can do it just with Photoshop and AE.

The text or images can be created as a long strip in photoshop and keyframed to run over this 'cylinder' with motion blur. Use Easy ease to get a realistic slowdown for the end keyframes. Hope this workds for you. All the best.

Cheers :thumbsup:

Thanks Aaron - nice idea - I normally avoid this sort of thing for the inflexibility it causes but I think in this case it could work...

Hi Deano - I think we were talking about using Afx 3D rather than a separate 3D app - I was wondering if there's any way using Afx to get a pure rather than polygonal cylinder... I could step it all out to XSI but that adds in a whole rendering timescale to deal with... I'm trying to keep this as a simple Afx job. Your 'cheat' tho simple and effective doesn't (as far as I can see) solve the original problem - that of needing to distort the symbols to make them look as tho they're travelling round a wheel

The 'bulge' filter gives an effect very similar to spherize, and you can play with the settings giving it a bevel, etc...

Only problem is, it's production bundle only

I have the Production Bundle, and it is a beautiful thing :)

Y Bulge does the job ok - for the time being I've gone with the Optics Compensation filter tho

What about the invigorator AE plugin with an extruded "."?
That's if your shot needs it to be "3d".
