VIEW Structure

The "VIEW" is a common structure that appears in all game states that I believe stores the final information on the active camera, which is then converted into a projection matrix. Each Game State defines it's own VIEW struct. Below is both the struct and the initial values, when initialized by the NTSC 1.0 function located at 80091858:

 /* 0x00 */ u32 VIEW;            //0x56494557, or string literal VIEW
 /* 0x04 */ ptr graphicsContext; //stores address to the start of the Graphics Context
 /* 0x08 */ s32 viewportTopY    =   0;    
 /* 0x0C */ s32 viewportBottomY = 240;
 /* 0x10 */ s32 viewportLeftX   =   0;   
 /* 0x14 */ s32 viewportRightX  = 320;
 /* 0x18 */ float fieldOfView   = 60.0f;
 /* 0x1C */ float fogDistance   = 10.0f;
 /* 0x20 */ float zDepth        = 12800.0f;
 /* 0x24 */ float unk1          = 1.0f;
 /* 0x28 */ float unk2          = 0.0f;
 /* ... */
 /* 0x124 */ u32 unk_0x124      = 0;

Camera Structure

The Camera structure is a structure seen in at least in the "main game" game state that is used to represent a pin-hole? camera located within world space. The main game state defines and uses up to 4 camera structs at any one time. At Game Play + 0x790 is a pointer array to the four cameras used in game. These structs are allocated to game_play at the following locations:

Offset Usage
0x01E0 Follows the player
0x034C typically used for cutscenes
0x04B8 Used when Pierre dances
0x0624  ?
//union at the beginning of the struct. The following few bytes only applies to the first camera
  0x0000 f32 //?
  0x0004 f32 //tween time step (0 to 1)
  0x0008 f32 //?
  0x000C f32 //?
  0x0010 f32 //?
  0x0014 f32 //?
  0x0018 f32 //?
  0x001C s16 //?
  0x0050 f32[3] //xyz 1 (could be camera focus or loc)
  0x005C f32[3] //xyz 2 (could be camera focus or loc)
  0x007C ptr //Game Play
  0x0080 ptr //Follow Actor (Link)
  0x00FC f32 = Angle of View
  0x011C s32 //Index for 800EEE70 (camera behavior?) table. Stores next behavior when surfacing water?
  0x0124 = Focus Point tween list
  0x0128 = Camera Position tween list
  0x0142 s16 Camera S property //State, Index for 800EEE70 (camera behavior?) table
  0x0144 s16 Camera M property //Mode
  0x014C s16 //? flags?
  0x0164 s16 //?
  //known values: +0x01E0, +0x034C from game_play

the second camera:
 0x004 f32 //tween time step (0 to 1)
 0x008 s16 //tween point list array index

Camera Behavior Data

According to the Debug Rom's Camera Debugger (enabled by setting the halfword at 80210BA4 to 1, or setting RO00 in the memory editor), cameras have 4 primary properties: S, M, F, and I

  • S seems to stand for State. It acts as a global behavior for the camera.
  • M seems to stand for mode. This usually changes depending on Link's actions.
  • F is presumably the function executing the camera behavior logic
  • I is unknown


typedef struct //Camera S
    s32 unkFlags;
    z_Camera_M* m; //Pointer to array of Camera M data
} z_Camera_S

typedef struct //Camera M
    s16 f; //Sets function for handling camera movement
} z_Camera_M

Camera S Data

This table is located at Debug 8011D064; NTSC 800EEE70, B64DD0. The Camera S property can be set either through Link touching/being over polygon types, or it can be changed programmatically by actors.
