- 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.
