There are 2 tools in use:
Step1: Take photos
Step2: Generate mesh using Regard3d
Step3: fix up in MeshLab
- Screened Poisson Surface Reconstruction - Generate a water tight mesh, set reconstruction depth to 12
- Remove any vertices that don't contribute to the model
- Quadric Edge Collapse Decimation - Set the target number of faces to something reasonable
- Remove Faces from Non Manifold Edges - A edge should only be attached to 2 faces
- Parameterization + texturing from registered rasters - Set texture size to something big
- Export mesh as .obj file
