360 FOV
This mod blends various projections to allow FOV to be set up to 400° and still maintaining visual quality.
Preview
110° to 400°
What it does
The effect is always on while a world is loaded. The mod captures the world as a six-face cubemap and reprojects it in a single shader pass. As you raise the FOV slider (now 400 instead of vanilla's 110) the shader switches through a chain of projections:
| FOV range | Projection |
|---|---|
| below 90 | Rectilinear, vanilla projection |
| 90 to 160 | Cross-fade rectilinear into the Panini/stereographic hybrid |
| 160 to 220 | Cross-fade the hybrid into fisheye (azimuthal equidistant) |
| 220 to 300 | Cross-fade fisheye into Mercator |
| 300 to 340 | Pure Mercator |
| 340 to 360 | Linear cross-fade Mercator into equirectangular |
| 360 and above | Equirectangular, the full sphere is shown at 360, past it the view wraps |
Usage
Raise the FOV slider in vanilla video settings; the projection follows it automatically. No keybind or toggle, it's a drop-in replacement for how the world is rendered at wide FOV.
Config
config/paniniprojection.json is created on first launch and read once per session (edits need a
restart):
| Key | Default | Effect |
|---|---|---|
splitScreen |
false |
Splits the window into a forward half and a rear half, each at the full slider FOV. Meant for two monitors at slider 180, giving a seamless full-sphere view. |
invertSplitScreen |
false |
Swaps which half is forward/rear (and where the GUI lives) in split screen. |
faceSizeCap |
2048 |
Upper bound in pixels on the six capture faces. Raising it sharpens high FOVs at a steep VRAM cost. Clamped to 256-4096. |
lowResTopBottomFaces |
false |
Halves resolution on the up/down capture faces (except the one you're looking at) to save performance |
antialiasSamples |
4 |
Supersample tap count in the reprojection pass: 1, 2, or 4. |
Note:
FOV mismatch: Vanilla's slider sets a vertical FOV while the projection shader works in horizontal FOV, so the same number maps to a different angular extent depending on your aspect ratio and which projection stage you're in.
Performance: Rendering a full surround view can take up to six world passes per frame instead of one (can decrease FPS)
Bugs: Several rendering edge cases (billboard/particle handling, shader mod compatibility, untested corner geometry, etc.) haven't been verified in-game yet
