;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. | |||
