MiXR: Harvesting and Recomposing Geometry from Real-World Objects for In-Situ 3D Design

Arthur Caetano, Demircan Tas, Faraz Faruqi, Misha Sra, Mustafa Doga Dogan, Niccol\`o Meniconi, O\u{g}uz Arslan, Ruofei Du, Stefanie Mueller

MiXR lets users harvest real-world geometry segments in XR and assemble them by direct manipulation before generative AI synthesizes the final model.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In a controlled user study (N=12), participants using MiXR rated their designs as significantly closer to the target, felt more in control, and experienced lower cognitive workload compared to a generative composition baseline.

C2weakest assumption

That generative AI can reliably synthesize coherent, artifact-free 3D models from arbitrary user-specified spatial compositions extracted from real-world captures.

C3one line summary

MiXR enables in-situ 3D design by harvesting real-world geometry for user-defined compositions that generative AI then refines, outperforming text-only generative methods in control and fidelity per a 12-person study.
