Imagine Object File

Imagine Object File, a newer version of TDDD, is used for 3-D rendering data by the Impulse Imagine software for the Amiga and for x86 PCs.

Identification
Files begin with.

This does not distinguish it from the original TDDD format. There does not appear to be any simple way to do that, but you could look for IFF chunk names that are used only in the Imagine format (BBOX, SPC1, PRP1, ...), and that are used only in the original format (INFO, TPAR, EXTR, ...).
