I’m after some advice/help for native Ai function which can replicate the keystone correction effect:

CURRENT KEYSTONE PROCESS Ai CS3 USING PLUGIN • New Ai doc • Set point of origin (0x 0y) • Graphic placed at scale 1:10 or 1:100 (0x 0y) • Write editable text “Projector” and position anchor point to (0x 0y) • Select Projector text • Object > Transform > Move, and type 100mm into Vertical field in the dialogue (in this example, +Y offset 1:10) • Select graphic and Projector text • Navigate to Keystone Filter • Type in dimensions to dialogue box, OK.

@ Billy Kerr llustrator's 3D effect has always been "best guess" and has never really been anywhere close to real 3D. Real 3d bases extrusion and perspective on the camera or view angle. Illustrator bases extrusion and perspective on the object and the center of its front plane.

@ GerardFalla, default setups cannot be predetermined, as the lantern can be positioned anywhere XYZ offsets, as per clients request.

    the plugin will need to be rewritten... with quotes of £7-£10k - sounds like you need a developer – Luciano Jul 12 at 13:47

    If you have been a paying CS3 user in some distant past, get CS3, Adobe still serves the purchasers of old stuff. It's also possible that someone else who has that right, helps you. – user287001 Jul 12 at 14:02

    Your company would need to decide to either use CS3 for that plugin of pay that 10k. Or look for different plugin for Cs6 and above. – SZCZERZO KŁY Jul 12 at 14:38

    I feel like there's a simple point being passed over in all this... the distortion being applied to the resulting file for keyframe compensation is a single-plane perspective distortion... which Illustrator already has tools to accomplish. Perhaps what's simplest (Occam's Razor) is to determine the necessary distortions for each commonly-used projector setup for your company, save the resulting distorted rectangles, and use those to run Envelope Distort > Use Front Mesh. This will keyframe the underlying selected items. – GerardFalla Jul 12 at 15:17

    @GerardFalla - I agree. Perhaps even the 3D Rotate effect would work. It's even simpler and can distort for perspective. see example here – Billy Kerr Jul 12 at 19:21
