I want to present some 3D models to my clients via email. I don't know what apps they have installed and I can't have then install any apps, most of them have a strict app policy.

What 3D formats does Preview for iOS support?

  • Preview for iOS? It doesn't exist as an app, though mail will preview some things. Empirically, .dae isn't one of them

  • You're right. I'm looking for something UIDocumentInteractionController can handle.

You probably should look at what is listed here: QLPreviewController

Clipped from the developer site:

A Quick Look preview controller can display previews for the following items:

  • iWork documents

  • Microsoft Office documents (Office ‘97 and newer)

  • Rich Text Format (RTF) documents

  • PDF files

  • Images

  • Text files whose uniform type identifier (UTI) conforms to the public.text type (see Uniform Type Identifiers Reference)

  • Comma-separated value (csv) files

As far as I know, the only format that could embed 3D information in the format is the PDF file. But does QLPreviewController render it? I do not know.

Maybe an alternative for you would be to make a WebGL website that you link your customers to?
