Meshing: taking points to triangles
You can't print points, but you can print triangles. MeshLab will help us take our model there!
If you don't already have MeshLab working and a cleaned model, go to the previous page and follow those instructions.
Opening the file
To mesh, we're going to open our cleaned and exported model in MeshLab. Select File > Open and find your .obj file.
Compute vertex normals
To mesh, we need to know the "vertex normals" for each point, which
helps the meshing algorithm know where to draw triangles. Select Filters > Normals, Curvature, and Orientation > Compute normals for point sets.
We want very smooth normals, so set Number of Neighbors to around 100.
Set the Octree Depth to around 7. A
higher depth will produce high-resolution meshes, but take longer and
sometimes fail to complete. Usually we run one at 6 or 7, make sure it
looks good, and then use 7 or 8 for the final version.
Now you're almost ready to print! You probably want to add a flat surface to start your print on which is covered in the next page Editing with Blender.
