  • Free trialonly Structure
  • Most featuresStructure · 4 of 4

MeshLab and Structure score identically on our rubric (7.9 out of 10) for 3d scanning software; MeshLab sits at #6 and Structure at #9 in our editorial ranking, so the choice comes down to fit.

MeshLab offers free plan; Structure doesn't. Structure offers real-time capture; MeshLab doesn't.

MeshLab is the better fit for free mesh cleanup and reconstruction. Structure is the better fit for structure Sensor and Apple depth capture.
