MipMap has released MipMap Desktop 3.3, which adds first person navigation, calibration and measurement tools to gaussian splatting scenes.
MipMap Desktop 3.2 combined aerial and ground capture in one reconstruction and added link and QR code sharing, with measurement tools on cloud results. MipMap Desktop 3.3 measures the splat model directly inside the desktop app and publishes to SuperSplat.
Gaussian Splatting Walk Mode turns a reconstruction into a walkable scene. Collision data is generated by choosing an environment type, Object, Indoor or Outdoor, and adjusting the voxel size. Movement works by clicking the ground or with WASD keys, with jumping, speed control and an adjustable walking height. An improved skybox completion step fills areas the source imagery did not fully capture, giving a more consistent background across viewing angles during a walk.
Scale calibration sets real world scale from two points and a known distance, which MipMap says is particularly useful for models built without GPS data. Ground plane calibration levels a tilted scene from three points. Gaussian Measurement then returns coordinates, distances and areas from the splat, with output in geographic coordinate systems. MipMap tested it on an office captured with an Insta360 panoramic camera and describes the results as "remarkably close to the actual dimensions of the furniture." No error figure is published for that test.
Aerial triangulation runs faster and gains an AT Editing mode, where camera positions and sparse points can be reviewed in the 3D viewport and deleted before reconstruction. Gaussian splatting reconstruction also runs faster, by MipMap's comparison against version 3.2.3, though the post's text quotes no timings.
A finished model can go straight to SuperSplat. After a SuperSplat account is connected with an API key, MipMap Desktop 3.3 uploads the model from inside the app and returns a shareable link. Smaller changes include an updated sharing page, smoother mobile viewing, camera pose visualization in splat scenes, steadier ground plane estimation for Insta360 panoramic data, and a fix for inconsistent left and right lens frames when extracting panoramic video frames.
MipMap Desktop 3.3 is available now.
