Photogrammetry, 3D Scanning, Modelling - Coggle Diagram
Photogrammetry
Engineering
Topographic maps, meshes, point clouds
Medical
to help develop diagnoses without invasive procedures.
Textures are automatically added from the photos
requires specific lighting conditions
3D Scanning
Requires specialized hardware and software
Hardware is usually expensive
Engineering
Ensure parts will fit together on first try
Medical
Exact image of patient and issues without unnecessary invasive procedure
Useful for creating complex shapes that would be harder to model.
Faster Data collection
Object that is being scanned needs to be static
requires highly specific conditions
Reduce number of prototype designs
Quality control of existing objects
Modelling
More attention to detail - benefit to hand modelling
Useful for creating objects that don't exist
Expensive
Lots of different art styles can be achieved
Soft body, moving objects etc
recommended for character modelling
Time consuming
better to model simple objects over scanning or photogrammetry
