Gaussian Splatting mode
Gaussian splatting capture on iPhone
Voxelio Gaussian Splatting mode records the calibrated source data used by splat reconstruction workflows: ARKit video, camera poses, intrinsics, and metadata. On depth-capable devices, it can also save depth maps and a point cloud.

- Optional point cloud on depth-capable devices
Device requirements
Requires an iPhone supported by Voxelio and ARKit. Depth maps and point cloud output require a depth-capable device; lens correction remains off for calibration consistency.
Source capture for splat reconstruction
This mode is designed for users who already have a Gaussian splatting reconstruction or training pipeline. Voxelio records the source bundle on iPhone, then lets your downstream tools handle the reconstruction step.
Every AR frame is recorded
Gaussian Splatting mode captures each AR frame so the exported session can preserve frame-by-frame motion, pose, and camera context. That helps avoid gaps that can appear when only sparse keyframes are saved.
Pixel calibration stays consistent
Lens correction stays off in this mode so calibration data matches the recorded pixels. That is important for workflows that depend on camera intrinsics, image coordinates, and pose alignment.
Depth extras on capable devices
When AR depth is available, Voxelio can also save depth maps and a point cloud with the video and pose data. These extras are optional source signals for workflows that can use depth-aware input.
Use it when the dataset matters
Choose Gaussian Splatting when you need a video and pose dataset rather than an immediate OBJ, USDZ, or PLY export. For finished meshes, use Mesh Mode or 3D Objects; for structured rooms, use Room Plan.

Dual Camera
Capture synchronized wide and ultra-wide HEVC video on supported iPhones, with single-camera fallback, intrinsics, and capture controls.
Mesh Mode
Scan rooms and spaces with iPhone LiDAR, then export OBJ + MTL meshes with optional texture atlas, photo textures, or classification colors.
Point Cloud Mode
Capture colored AR depth samples on supported iPhones and export PLY point clouds with density, confidence, max depth, and preview controls.
Room Plan
Use Apple RoomPlan in Voxelio to scan structured rooms, detect walls, openings, furniture, and export USDZ + JSON.
3D Objects
Create on-device USDZ models of individual objects with Apple Object Capture and PhotogrammetrySession in Voxelio.
FAQ
Gaussian Splatting questions
- Does Voxelio reconstruct the Gaussian splat for me?
- This page describes source capture. Voxelio records video, poses, intrinsics, and metadata that can be used by separate splat reconstruction or training tools.
- Why is lens correction disabled in Gaussian Splatting mode?
- Lens correction stays off so the exported calibration data matches the recorded image pixels used by reconstruction workflows.
- Are all AR frames saved?
- Yes. The mode records every AR frame rather than saving only sparse keyframes.
- Can Voxelio export depth with the splatting bundle?
- On depth-capable devices, Voxelio can save depth maps and a point cloud alongside the video and camera data.
- When should I use Mesh Mode instead?
- Use Mesh Mode when you want a LiDAR mesh export such as OBJ + MTL. Use Gaussian Splatting when you need source data for a splat pipeline.
