3D MODELS FROM medical images:
3 main steps
- thresholding
- segmentation
- mesh generation
steps once 2D images done (4)
- 2D image

- iInVesalius 3
3D modeling license software (4)
- amira
- mimics
- osirix
- radiantdicom
what information goes into 3D modeling system
points cloud
what is a points cloud
list of spatial coordinates
what 2 files can come out of 3Dmodeling system
- STL format (polygonal model)
2. IGES format (solid/parametric model)
main steps from point cloud to the model (6)
- point cloud decimation
- remove useless parts
- repair/fill holes
- remeshing
- poligonal model
- solid/parametric model
FROM 3D SCANNING (not medical images)
3D scanning open source software (3)

2. virtual humans
source for residual limb modeling (2)
- external: laser scanner
2. internal: CT and MRI
VIRTUAL HUMANS 2 uses (2)
- ergonomic analysis
2. detailed biomedical models
what is a virtual manikin
kinetic chain of rigid links connected by joints
why use a virtual minikin (2)
- predict comfort & posture
2. analyze & prevent musculoskeletal disease
example of virtuanl minikin use
analyze supermarket worker movements for injuries
