''This article is for the SCAN format from Metroid Prime 2 and 3. For other revisions of this format, see [[SCAN (File Format)]].''


The '''.SCAN file format''' describes SCAN POI data and has references to several resources. This variation of the format is completely different than its [[SCAN (Metroid Prime)|Metroid Prime]] counterpart.
The '''SCAN file format''' describes scannable objects. The format's been updated since Prime 1; the data is now embedded into a script object, using the [[Scriptable Layers (Metroid Prime 2)|scriptable layers]] format. There was also some additional data added to the format to set up the model that displays in the logbook.
 
{{research|minor|There's a couple remaining unknown parameters.}}

== Header ==
== Format ==
The header is rather simple and consists of the following:
 
{|class="wikitable"
The SCAN format sets up a small script layer that contains a single [[#ScannableObjectInfo|ScannableObjectInfo]] instance.

== SNFO Chunk ==
=== ScannableObjectInfo ===
The SNFO header is simply a FourCC and the total length in bytes. Due to the fact that there is nothing in the header to determine which version of SCAN we're working with, we have to rely on the size of the SNFO chunk. If it's less than 0x0251 bytes, it's Metroid Prime 2. Otherwise it's Metroid Prime 3.
 
This section of the file embeds a ScannableObjectInfo script object.

==== ScanInfoSecondaryModel ====
 
This struct is used to embed a resource that can be attached to the model in the logbook. The mesh can be either a [[CMDL (Metroid Prime)|model]] or an [[ANCS (File Format)|animset]].

! ID

Other than that, SNFO is entirely unknown.
=== Dependencies ===


== Dependency List ==
After the ScannableObjectInfo instance, there's a list of the scan's dependencies present. The list follows the same format as the [[DGRP (File Format)|DGRP]] format.
The dependency list follows the same format as [[DGRP (File Format)|DGRP]]
