-====== Clean up a 3D scan ======+====== Clean up a 3D scan made with the Occipital Structure scanner ======
  
 +The 3D files from the Structure scanner often have holes and unwanted geometry. After following this guide you'll get a watertight model that is ready for (colour) 3D printing. A basic understanding of mesh manipulation in Blender is necessary.
 +This guide uses Meshmixer, but here is a [[3d_modeling:blender:clean_up_occipital_3d_scan|guide]] that describes this process for Blender.
  
-==== Occipital Structure 3D scanner ==== +===== Open the file ===== 
-Cleaning up a 3D scan with Meshmixer is easy, but alternatively use [[3d_modeling:blender:clean_up_occipital_3d_scan|Blender]] for a more manual procedure with more control.+The structure scanner delivers the 3D object in 3 parts: 
 +  - ''Model.obj'' is the 3D object 
 +  - ''Model.jpg'' is the texture file 
 +  - ''Model.mtl'' is a file that links the object to the texture. 
 +{{:structure_3d_scanner:cleanup_files.jpg?nolink|}}
  
-  - Import & orient the model upright: ''Edit > Transform''.+You only have to open the ''.obj'' file. The program will find the other files on its own: 
 +  Click 'Import' and select the ''.obj'' file. Alternatively go to ''File > Import''
 + 
 +=== Prepare model === 
 +  - Orient the model upright: ''Edit > Transform''.
   - Cut away unwanted geometry: ''Edit > Plane Cut''.   - Cut away unwanted geometry: ''Edit > Plane Cut''.

 +=== Join disconnected sections ===
 +Objects from the structure scanner come in overlapping parts. This might cause problems for 3D printing.
 +  - Join the disconnected sections (blue lines indicate boundaries): ''Edit > Close Cracks''.
 +{{:3d_modeling:meshmixer:meshmixer_occipital_cleanup_02_close_cracks_arrows.jpg|}}
 +
 +=== Delete loose parts ===
 +  - In ''Select'' mode, click anywhere on the part you want to keep.
 +  - Expand the selection to all connected vertices: ''e''.
 +  - Invert the selection: ''i''.
 +  - Delete the loose parts: ''x''.
 +{{:3d_modeling:meshmixer:meshmixer_occipital_cleanup_03_delete-loose_arrows.jpg|}}
 +
 +
 +  - Save your project(!)
  
 +=== Make the model 3D print ready ===
 +  - Make the mesh solid: ''Edit > Make Solid''.
 +      - Set the solid type to ''Accurate''
 +      - Increase Solid Accuracy and Mesh Density until you're happy with the result. Press Accept.
