360 FOV

360 FOV

Minecraft mod that extends the FOV range from 110° to 400° using a combination of projection techniques.

How it works

The mod renders the surrounding world into a six-face cubemap and reprojects it in a single shader pass.

Different projections are blended together as the FOV increases. By default:

| FOV | Projection |
| ———-: | ————————————————————- |
| < 120° | Rectilinear |
| 120°–160° | Rectilinear → Panini/stereographic hybrid |
| 160°–220° | Panini/stereographic hybrid → Fisheye (azimuthal equidistant) |
| 220°–300° | Fisheye → Mercator |
| 300°–340° | Mercator |
| 340°–360° | Mercator → Equirectangular |
| 360°+ | Equirectangular |

At 360°, the entire sphere is visible. Above 360°, the view wraps around.

Wherever the view is pure Rectilinear, the mod hands the frame back to Minecraft’s normal renderer at the matching FOV, so normal FOVs cost no extra performance. Every other FOV is drawn from the cubemap.

Usage

The mod uses the vanilla FOV slider. Set the FOV in Video Settings and the projection will update automatically.

The thresholds can be changed in game under 360 FOV Settings → FOV Thresholds…. The bar covers every FOV from 30° to 400°. Each point on the bar sets the projection used from that horizontal FOV upward, and the view blends into the next point’s projection between two points. Click the bar to add a point (up to 12), drag to move one, and right-click to remove one. The available projections are Rectilinear, Panini/Stereographic (the pitch-dependent hybrid above), Panini, Stereographic, Fisheye, Mercator and Equirectangular. Blends can be Ease Out, Linear or Smooth. Rectilinear stops widening above 170°, and Panini and Stereographic stop widening above 330°.

Configuration

Settings can be changed in game from Video Settings → 360 FOV Settings…, or with the Open 360 FOV Settings keybind (unbound by default, under Controls → Key Binds → 360 FOV). The keybind also works when Sodium replaces the Video Settings screen.

Settings are saved to config/fov360.json, which is created on first launch and can also be edited by hand. Edits made to the file while the game is running require a restart. Reset All in the settings screen restores every default.

Known issues

• FOV mismatch: Minecraft’s FOV slider represents vertical FOV, while the projection shader uses horizontal FOV. The resulting angular range therefore varies with the aspect ratio and projection being used.
• Performance: The surround view can require up to six world render passes per frame instead of one.
• Rendering edge cases: Billboard and particle rendering, shader mod compatibility, and some corner geometry have not been fully tested.
