MATLAB Code for Creating a Mesh from a Bitmap Image

license - BSD language - MATLAB category - hobby status - unmaintained

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.

Example

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

Compatibility

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

This code share some files with laser_cut_matlab_slicer.
