I study it and try long time to do one, but still can not do one exactly like that, so I just guess there must trick, or there is other different technical in iPhone 7 animation. What do you think?
Or anyone would like do one to show what you think?
Looks to me like a 3D iPhone model in a 3D studio light rig with a rotating point light and a fill in at the end then rendered out as an image sequence, like Hans wrote.
first of all you’ll need a imagesequence (source might be photoshop, apple motion a 3d-rendering tool … to be continued …) … then just do a forumsearch for imagesequence and here you go
The curved edges element poses a problem. If you want to create a simulated 3-D object made of rectangular planes, check out the fireplace animation. To change the angle to match the source image, you can take the entire thing, group it, tilt it back and rotate it.
