360 FOV

# 360 FOV This mod blends various projections to allow FOV to be set up to 400° and still maintaining visual quality. > 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 ## Preview Preview in Modrinth gallery </details> **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. | ## Attribution The projection math is ported from (https://github.com/shaunlebron/flex-fov) by Shaun LeBron, itself a fork of (https://github.com/18107/MC-Render360) by 18107.
