;IDXA usage
*Two kinds of IDXA are used in [[AKEV]]: they define quads affected by [[env_show]].
*Two kinds of IDXA used in [[AKOT]] define the quads and BNVs intersected by a leaf.
*Two kinds of IDXA are used in [[M3GM]]: triangle strips and face normal groups.
*[[ONOA]] uses several similar IDXA, one to store the quad IDs of every object.
;High bit
:The high bit is only used for triangle strips in [[M3GM]].
:It is set for the first vertex index of every triangle strip.
;AKEV indices
:Both IDXA have the same number of entries, equal to the number of togglable quads.
:The first IDXA lists the quad IDs (index into AGQG, AGQC, AGQR and AGDB arrays).
:The second IDXA assigns a gunk ID to every quad (one or more quads per gunk).
;AKOT indices
:The first IDXA lists the IDs of the quads intersected by octtree leaves, one leaf after another.
:The leaf specifies how many quad IDs Oni should read from the IDXA and where it should start.
:Same thing for the intersected BNVs: the leaf specifies the size and position of the BNV list.

IDXA usage
  • Two kinds of IDXA are used in AKEV: they define quads affected by env_show.
  • Two kinds of IDXA used in AKOT define the quads and BNVs intersected by a leaf.
  • Two kinds of IDXA are used in M3GM: triangle strips and face normal groups.
  • ONOA uses several similar IDXA, one to store the quad IDs of every object.
High bit
The high bit is only used for triangle strips in M3GM.
It is set for the first vertex index of every triangle strip.
AKEV indices
Both IDXA have the same number of entries, equal to the number of togglable quads.
The first IDXA lists the quad IDs (index into AGQG, AGQC, AGQR and AGDB arrays).
The second IDXA assigns a gunk ID to every quad (one or more quads per gunk).
AKOT indices
The first IDXA lists the IDs of the quads intersected by octtree leaves, one leaf after another.
The leaf specifies how many quad IDs Oni should read from the IDXA and where it should start.
Same thing for the intersected BNVs: the leaf specifies the size and position of the BNV list.
