| + | ===== Vertex Structure ===== | ||
| + | |||
| + | Vertices are points in 3D space that are used in drawing triangles. This structure is the same no matter which graphics microcode you use. Each vertex takes up 16 bytes. | ||
| + | |||
| + | ''[<color red>XX XX</color>] [<color green>YY YY</color>] [<color cyan>ZZ ZZ</color>] [<color lightgray>FF FF</color>] [<color orange>UU UU</color>] [<color #AA88DD>VV VV</color>] [<color pink>XR</color>] [<color lightgreen>YG</color>] [<color lightblue>ZB</color>] [<color lightgray>AA</color>]'' | ||
| + | |||
| + | | <color red>XXXX</color> | short | Position on X axis | | ||
| + | | <color green>YYYY</color> | short | Position on Y axis | | ||
| + | | <color cyan>ZZZZ</color> | short | Position on Z axis | | ||
| + | | <color lightgray>FFFF</color> | ushort | Flag. Unknown usage, usually just 0000 | | ||
| + | | <color orange>UUUU</color> | short | Texture Coordinate on the U axis | | ||
| + | | <color #AA88DD>VVVV</color> | short | Texture Coordinate on the V axis | | ||
| + | | <color pink>XR</color> | byte or ubyte | X unit vector of normal or Red color* | | ||
| + | | <color lightgreen>YG</color> | byte or ubyte | Y unit vector of normal or Green color* | | ||
| + | | <color lightblue>ZB</color> | byte or ubyte | Z unit vector of normal or Blue color* | | ||
| + | | <color lightgray>AA</color> | ubyte | Alpha (Transparency)<nowiki>**</nowiki> | | ||
| + | |||
| + | * You cannot use vertex colors and vertex lighting at the same time. Normals are used if the geometry mode ''G_LIGHTING'' bit is enabled, otherwise the RGB colors will be used instead. (see: [[rcpstructs#rsp_geometry_mode|RSP Geometry Mode]]) | ||
| + | |||
| + | <nowiki>**</nowiki> Vertex alpha cannot be used when fog is enabled. The vertex will use the fog alpha value instead. | ||
