3DGS <span class="text-transparent bg-clip-text bg-gradient-to-r from-[#2DD4BF] to-[#14B8A6]">Workflow Guide

Gather images or video of your scene from multiple angles

Smartphone

Modern phones (iPhone LiDAR, Android ToF) work great for 3DGS. Shoot in good lighting with 60%+ overlap between shots.

Camera (DSLR / Mirrorless)

High resolution and dynamic range for best reconstruction quality. Use fixed focal length and manual exposure.

360 Camera

Rapid coverage with fewer captures. Ideal for indoor spaces. Insta360, OSMO360 are popular choices.

Drone

Essential for large outdoor scenes — buildings, landscapes. DJI models with automated waypoint shooting work well.

Scaniverse

Free mobile scanner from Niantic with on-device Gaussian Splatting and PLY/SPZ export for quick field capture.

Step 2

Alignment

Reconstruct camera poses and build a point cloud from your images
