Fly a real-feeling FPV drone through photoreal 3D Gaussian Splatting scans, right in your browser. ShramkoGSFPV loads scenes straight from SuperSplat, flies them with a quadcopter model that has four motors, a mixer, a rate PID and Betaflight-compatible rate curves, crashes you into real walls with swept voxel collision, and takes your own radio (EdgeTX over WebHID), a gamepad or touch sticks. WebGPU, the MIT-licensed PlayCanvas engine, nothing to install. Created by Andrii Shramko.

Status: alpha, live since September 2026. The site, the simulator and the measurements below run in public. Every feature claim in this README is either measured (a JSON file in
evidence/with its method) or explicitly marked not tested yet. Most pass/fail checks also run a negative control, a deliberately broken case that must fail; where a check has none, or a weak one, the line says so. The radio path has been tested with a simulated EdgeTX radio, not yet with a real one.
Real screenshots of the live simulator, taken on 2 October 2026 by tools/bench/src/screens.ts in system Chrome on a real GPU (1920×1080 at device scale 2, so the menus stay sharp). A menu is shown as itself with a little of the scene around it; click any picture for the whole screen. The calibration screens use the simulator's built-in simulated EdgeTX radio; the flights are flown by its test pilot or from the keyboard and frozen while really flying. All 39 screens, phone-sized ones included, are in docs/screenshots/ and on the landing page.
 Voxel grid over the scan — The walls you crash into, drawn over Andrii's Tunis scan in height colours: V switches between off, over the scan and voxels only; the chip names the style and the voxel size. |
 Voxels only — The scan hidden and only its 5 cm walls left, as solid cubes (Modlinek Villa): fly the grid alone and see every surface you can hit. |
 Tunis old town — The flight view on Andrii's Tunis scan: arm state and flight mode, battery voltage and flight time, throttle, speed, altitude and the keys. |
 Throttle found — Each stick is found by moving it: the wizard names the channel, offers Reverse and moves on when the stick is back. |
 Summary panel — Pause shows this flight's stats beside the session and all-time ones, the scene size, saving as video, every menu item and every key. |
 Settings — Every setting on one screen, by group and with search; here Crashes & respawn: crashes, threshold, automatic respawn, delay, where and how far back, the invisible platform. |
 Flight stats — Disarm after a flight and a card like the goggles OSD shows air time, top speed and altitude, distance, battery, current, mAh used, G-force and average throttle. |
 Flight mode — Angle by default; the chip, M or a switch on your radio picks Acro, Angle or Horizon. |
 Automatic respawn — The toast counts down; 2 s after the crash the drone is back 5 s along its path, still armed. Enter stays, R goes to the start, N and F load another scene. |
 Crash — With automatic respawn off, or after Enter: the impact speed, the wreck with debris, then rewind 5 s, back to the start, a 10-second replay, the flight log or another scene. |
 SuperSplat tab — superspl.at's catalogue in the picker with its sorting, time, walls and download filters, search, Random top-rated and a star for favourites. |
 Scene size — [ and ] scale the scan around the drone from 0.25× to 100×: fix a scan not in true metres, or shrink yourself and fly a room like a city. Kept for each scan; the walls' block size follows. |
 Recording — F9 records 60 fps video of Andrii's scans; Auto records every flight into the folder you choose, and the bar says what was saved where. |
 Video from the flight log — The flight rendered again from its log as 60 fps video at 1080p, 1440p or 4K, frame by frame; Cancel leaves no file. |
 Floating pieces dropped — Modlinek Villa with the pieces of its walls under 64 blocks removed: 44 phantom walls gone, for this scan only; the walls menu says what was dropped. |
 Walls on or off — The walls line on the credit opens the walls menu: the walls (collisions) switch, the voxel grid and the stored walls. Here the walls are off (C): the drone flies through everything, no crashes. |
 Six drones — BetaFPV-class presets with a rate curve each; every number says where it comes from: manufacturer, measured or estimate. |
 Betaflight import — Paste a CLI diff and its rates and PID fly the quad; every setting the simulator does not use is listed (here a test diff). |
 Keyboard — Every flying key on screen: Space arms, W and S throttle, A and D yaw, the arrows tilt, M self-levelling, V the voxel grid, C the walls. |
 Cinema mode — Full detail, automatic quality off, no HUD; Record saves an MP4 with the scan's credit in the picture. |
 Wireframe grid — The Winter Garden's 3.2 cm walls as a wireframe over the scan: see where a wall really is before you fly the line. |
 Floaters in red — Pieces of the grid that touch nothing else and are smaller than 0.5 m³ turn red, so a phantom wall in the plants stands out. |
 Winter Garden — Glass roof, plants and furniture, with the walls SuperSplat publishes for this scan: 3.2 cm voxels you really crash into. |
 Choose a scan — Andrii's scans, recent and favourite ones, filters for walls, type and flown, or a pasted SuperSplat link. |
FPV pilots train in simulators like Liftoff or VelociDrone because the physics and stick response feel right, but those sims only fly the maps someone built for them. Meanwhile people publish thousands of real places as 3D Gaussian Splatting scans — rooms, villas, streets, whole city blocks — and you can only walk or orbit through them.
ShramkoGSFPV joins the two: pick a real scanned place, arm, and fly it with a drone that behaves like the one in your hands. Rehearse an indoor line before flying it for real, plan a cinematic shot in the actual location, or fly your own house on the Moon.
The default craft is a BetaFPV Pavo20 Pro class 2.2″ cinewhoop, with five more presets: Pavo20 Pro II on 3S and 4S, Pavo Pico, Meteor65 Pro and Air65. Most scans are rooms and streets, where a 5″ freestyle quad has no room to move. On each preset card the spec rows (thrust-to-weight, weight, wheelbase, motor, battery) say where the number comes from: manufacturer, independent measurement or estimate. The card's maximum rate (°/s) and hover-throttle figures do not carry a source label yet. The thrust-to-weight of three presets (Pavo20 Pro 3S, Pavo20 Pro II 3S, Pavo Pico 2S) was measured in the model and is within 0.4 % of the preset value (b-fly-b9.json); the other three are not measured yet.
Status on 2 October 2026. Live means you can use it on https://gsfpv.flyreelstudio.eu today; In progress is being built now; Next is designed and queued. How each input device was tested is in Radios and devices, and the numbers behind the physics are in What is measured. The same list, in four languages, is on the landing page. The v0.3 items name the check that accepted them on the live site (JSON files in evidence/; the list is in evidence/2026-10-02/v03-release.json).

Can I turn off crashes in a browser FPV simulator? Yes. Switch Crashes off in Settings and a wall hit never ends the flight, so a beginner can keep flying.
Does it have angle / self-level mode? Yes: Acro (rate mode), Angle (self-levelling) or Horizon (levels, flips allowed). The default is Angle (self-levelling); the HUD chip and the M key switch it.
Does the drone respawn by itself after a crash? Yes: 2 s after a crash it is back in the air, 5 s before the crash, on an invisible platform. Both times are settings (0.5–10 s and 1–30 s).
Can I change the FPV camera angle and field of view? Yes, for each drone separately: camera uptilt 0–50° and field of view 70–150° (20° and 115° on the default drone).
Can I fly an FPV drone on the Moon or Mars? Yes: gravity is a setting (0–30 m/s²): Earth 9.81, Moon 1.62, Mars 3.72, zero-g or anything in between. Thrust on other worlds picks how the motors cope: Real (same motors), Keep thrust / weight or Auto throttle (stick centre hovers).
Can I use my own Betaflight rates and PID in the simulator?
Yes: paste diff or diff all from the Betaflight CLI. The rates (Betaflight, Actual, KISS or Raceflight curves), the PID and the throttle curve are set for the drone you fly; every drone keeps its own.
How hard can I hit a wall before it counts as a crash? That is the Crash threshold: 2–10 m/s for each drone, 4 m/s by default. Slower touches slide along the wall.
Can I fix a scan that has the wrong size? Yes: Scene size scales the scan around the drone (0.25×–100×) and is remembered for each scan.
Can I see the collision walls of a Gaussian Splatting scan? Yes: the Voxel grid shows the voxels you crash into, over the scan or voxels only.
Can I record 60 fps video of my flight? Yes: Frame rate is 30 fps or 60 fps, 60 fps by default.
Numbers from the JSON files in evidence/2026-09-24/ named in each row. The landing page's figures come from evidence/latest.json (rates, tunnelling, clearance, latency), and its build fails if a number is missing.
| Check | Result | How |
|---|---|---|
| Rate curves vs Betaflight 4.5.1 | 1880 points, max error 0 °/s in double precision | Betaflight's own rc.c compiled outside the repo with float promoted to double, vs our re-implementation; a float32 build differs by at most 6.3e-4 °/s (PROVENANCE). A deliberately wrong curve (x³ instead of x⁵ in Actual) misses the vectors by up to 280 °/s, so they tell the curves apart (a3-rates-vectors.json) |
| Flying through walls (tunnelling) | 0 in 200,000 straight passes | 1 ms swept test vs an independent resampling oracle at 5–34 m/s on 3 real scans and a 2 cm wall; the endpoint-only control misses walls, so the oracle is not blind (a5-tunnelling.json) |
| Determinism | same SHA-256 of the whole trace in Node and Chrome and at 30/60/144/240 Hz frame splits | Math.random injected into the core changes the hash (a6-determinism.json) |
| Replay from stick inputs only | same hash in a new tab; 1 LSB changed in one report → different hash and > 1 cm divergence | 30 s flight with a flip and a crash, on the live site (b-fly-b15.json) |
| Wall clearance, Pavo20 Pro | body stops 47.2 mm (median) beyond its own size on 5 cm voxel collision | 200 directions from 12 points; a record, not a gate, so it has no negative control (a8-clearance.json) |
| Stick-to-screen latency | display-limited: the test screen runs at 30 Hz (median 252 ms, blank-page floor 65 ms) | SendInput → Desktop Duplication marker, N = 220, lagFrames=2 control fires; camera measurement not done yet (a9-latency.json) |

- Scenes: any public SuperSplat scene by link (
superspl.at/scene/<id>,superspl.at/s?id=<id>) or id, loaded by the visitor's browser from the public CDN — the server never talks to SuperSplat. Scenes without collision data fly as "no walls" and say so (b-fly-b6.json,b-fly-b7.json). - Flight model: own code, re-implemented from Betaflight's published formulas (no GPL code copied): motor lag, battery sag, drag, airmode, angle mode for beginners. Every constant carries its source. Checked in Node (
a4-physics.json): hover, full-stick rates, motor lag, airmode at zero throttle, PID step response, drag (terminal velocity). Battery sag is only recorded as information (no pass/fail check); angle mode is not tested yet. - Crashes: impact speed decides; the wreck tumbles with debris (Rapier), then the crash screen offers a respawn at the start or at the last safe point.
b-fly-b12.jsonrecorded one wall hit, 4 debris pieces and a respawn into free space; it does not record which of the two points was used. Crash effects stay under the WCAG limit of 3 flashes per second: at most 2 flashes per second measured over 50 crashes, whole frame and quarters (b-fly-b17.json). - Gravity: Earth, Moon, Mars, zero-g or your own value, with an honest "same motors" mode and a "keep thrust-to-weight" mode. Measured on the live site: disarmed drops on Earth (9.59 m/s² for 9.81) and the Moon (1.617 m/s² for 1.62) (
b-fly-b16.json). That check has no real negative control yet: its control is a fixed flag in the harness, not a run that could fail. Mars, zero-g, a custom value and the "keep thrust-to-weight" mode are not tested yet in the app (zero-g is checked only in the Node core: angular momentum is conserved,a4-physics.json). - Replays: only stick inputs are stored; the flight is recomputed bit-exactly (
b-fly-b15.json). - Walls for scans published without them: one click builds collision in the browser with SuperSplat's own tool and defaults (
@playcanvas/splat-transform, 5 cm voxels). On a 2.1 M-Gaussian scan it takes about 25 s and the result is byte-for-byte identical to the command-line tool; scans above 4 M Gaussians are refused with the numbers (c-bake.json, which has no negative control of its own; 0 penetrations in 50,000 passes on the baked walls, with a control,c-a5-baked.json). - Cinema mode: finest level of detail, automatic quality off, and a WebCodecs recorder (H.264 MP4) for the showcase scans, with the scene's credit burned into the picture (
d-cinema.json: a 6 s, 179-frame test recording; the credit strip was checked on one frame, not frame by frame). - Quality governor: when frames start missing the display's refresh, render scale and splat budget step down, and come back when the GPU has room again. Measured: render scale 1 → 0.5 under load and back to 1 (
d-governor.json); the splat-budget step is not measured yet. - Your Betaflight settings: paste
diffordiff allfrom the Betaflight CLI (4.3–4.5, 2025.12) and the simulated drone gets your rates, PID and throttle curve; anything the simulator does not use is listed, anything ambiguous is refused with the reason. Checked on the live site for rates and PID with a 4.5.1 and a 4.4.3 diff written in the firmware's exact print format but with made-up values (d-bf-diff-import.json); the throttle curve, 4.3 and 2025.12 are covered by unit tests only, and diffs from real flight controllers are not tested yet. - Trajectory export: CSV or JSON at 100 samples per second, straight from the flight model. The CSV was checked on a 12.6 s flight (1,256 rows): the 125 positions sampled every 0.1 s equal the flight recomputed from the input log exactly, and a one-row shift is caught (
d-trajectory-export.json); the JSON export is not tested yet.

| Browser | Input | Status |
|---|---|---|
| Chrome, desktop | EdgeTX radio (RadioMaster, Jumper, …) as USB joystick over WebHID | tested in Chrome with a simulated EdgeTX radio; real radio not tested yet; Edge not run yet |
| Chrome / Edge, desktop | Gamepad, DJI controller as a gamepad | not tested on real hardware yet |
| Desktop Chrome, touch emulation | Touch sticks | tested only in emulation (375×812, 1024×768): the arm button, both sticks at once and the pause button work. Holding a hover was not checked (the craft sat 0.3–3.3 m above its hover target), and the check's negative control is not conclusive yet. Safari, iPad and Android browsers not tested yet |
| Firefox 155 (Playwright build) | Gamepad or touch sticks | the scene renders with WebGPU and the app offers a gamepad or touch sticks (flying there not tested yet); radios need Chrome or Edge (no WebHID) |
Have an EdgeTX radio? A short test report is the most useful contribution right now — open an issue.
How can I fly an FPV drone through a 3D Gaussian Splatting scan? Open https://gsfpv.flyreelstudio.eu, pick one of the showcase scans or paste any public SuperSplat link, connect your radio, gamepad or touch sticks, arm and fly. No install, no account.
Is there a free FPV simulator that runs in the browser? Yes — ShramkoGSFPV is free and MIT-licensed. It needs WebGPU, so desktop Chrome or Edge works best.
Can I use my RadioMaster / EdgeTX radio in the browser? Yes: set the radio to USB Joystick mode, open the simulator in Chrome or Edge, and the calibration wizard maps sticks, inversion and the arm switch. It has been verified only in Chrome with a simulated EdgeTX radio (Edge not run yet); real-radio reports are welcome.
Do I crash when I hit a wall, or fly through it? You crash. The drone's body is swept against the scan's voxel collision every 1 ms physics step, so even at 34 m/s it does not slip through a 2 cm wall: 0 penetrations in 50,000 passes at a 2 cm wall and in 150,000 more on three real scans.
Is the flight physics like Betaflight? The rate curves match Betaflight 4.5.1's own code with 0 error at 1880 points when both are computed in double precision (a float32 build differs by at most 6.3e-4 °/s); the PID and filters follow Betaflight's structure and default gains. It is a simulator, not a certified replica.
Can my AI agent set this up? Yes — see below.

Andrii Shramko — FPV pilot and 3D/4D Gaussian Splatting specialist, author and maintainer of ShramkoGSFPV.
I am passionate about this idea, always open to interesting people and ready to help teams bring incredible projects to life. If you are an FPV pilot, scanning studio, drone maker, simulator developer, 3DGS platform, researcher or investor — let's talk about partnership, integration, licensing, sponsorship or funding. I am ready to assemble and lead a team around it.

Built on the MIT-licensed PlayCanvas Engine and SuperSplat viewer (collision code vendored, see NOTICE), Rapier (Apache-2.0) for the wreck, and formulas read from Betaflight 4.5.1. Thanks to SplatFPV, an earlier browser experiment that proved the idea works.
