mesh_from_bitmap_matlab
MATLAB Code for Creating a Mesh from a Bitmap Image
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.
- 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.
