Pikmin camera parameters

To do: There are some undiscovered parameters. Let's try to figure them out! See the Extra Information section for more details.

Located in /dataDir/camera/, there are three BIN files for camera parameters.

  • camepara.bin - Used in the final game.
  • _camepara.bin - Features a different set of [Far : Flat] parameters and a different value in the header[unsure]. It likely is a backup file left there by the developers while fine-tuning the camera.
  • 撮影camepara.bin - The camera settings used in the Creature Montage and many pre-release trailers. 撮影 translates to "shoothing" in regards to photography, likely referencing its role in recording gameplay.

Unlike many other parameter files, the camera parameter files do not feature labels preceding the values. Instead, the values are presented one after another. Note: because there are no labels to denote the positions of values, they will be henceforth referred to by their hexadecimal offset and/or purpose in the file.

Like many other parameter files, the values are IEEE-754 floating point decimals with a few 32-bit integers thrown in here and there.

Vocabulary[edit]

Toggled with the R trigger:

  • Near = The first zoom level, nearest in the vanilla game.
  • Mid = The second zoom level, middle in the vanilla game.
  • Far = The third zoom level, furthest in the vanilla game.

Toggled with the Z trigger:

  • Flat = The normal viewing angle.
  • Bird = The aerial viewing angle.

Other:

  • Plucking = The camera setting when Olimar is plucking Pikmin (this feature gets disabled after 100 plucks).

Table[edit]

In this table, camepara.bin is used as a baseline. The other, unused camera parameter files have values omitted if they are identical to the final file's values.

Extra information[edit]

By default on day 1 (the tutorial), the camera is set to [Near : Flat] before immediately switching and locking to [Plucking].

  • Though you were probably already aware, the camera usually defaults to [Mid : Flat] whenever one lands in a stage.

The fifth parameter in each camera setting grouping has produced observable effects. However, they only occur in the OpenGL / Dolphin System.

  • Setting [Mid : Flat] to an extremely large value (0x7F7FFFFF is the largest) and landing in any area causes a nlibgeometry: !normalize:zero:-1.#IND00 error to be thrown, crasing the application.
  • Setting [Mid : Flat] to 0x7A04B1E4, landing in the Forest of Hope, and moving at all causes a nlibgeometry: !normalize:zero:-1.#IND00 error to be thrown, crashing the application. This value is the largest this parameter can be set before the game crashes on its own from the same error.

Presumably, there are parameters for both pressing the L trigger all the way down and just partially (or holding the L trigger all the way down for a certain length of time). Figure those out.

For an unknown reason, the OpenGL / Dolphin System is able to function without any camera parameter files. The parameters it pulls out of seemingly nowhere are unlike any file available. It most closely resembles _camepara.bin, though that might be a coincidence.

  • To add to the mystery, I have in my notes that attempting to input data the engine determined "invalid" resulted in these parameters instead[unsure]

Parameter 0xE0 is only present in the final camera parameters file. It does not seem necessary for the function of the camera, so it could be vestigial or a mistake.[unsure]

There are no version differences for the camera parameters.
