This MATLAB code generates a mesh from a black and white bitmap image:

• Find the contour of a black and white bitmap image (raster)
• Simplify the contour with a specified tolerance
• Mesh the shape (handling of holes and multiple domains)

This code uses the MATLAB PDE toolbox and generatates a FEM mesh (FEMesh object). However, the mesh can be used for other purposes than FEM simulations, such as 3d printing.

Look at the example run_example.m which generates the following mesh:

• Tested with MATLAB R2018b.
• The image_toolbox is required (for contour detection).
• The map_toolbox is required (for contour simplification).
• The pde_toolbox is required (for meshing).
• Compatibility with GNU Octave not tested but probably problematic.

This code share some files with laser_cut_matlab_slicer.
