Mesh Parameterization

Setup

To run this project, download the folder mesh_parametrization and import the package by using

from mesh_parametrization import mesh_deformation

Usage

Import mesh

Import the mesh by using the function read_mesh:

mesh = read_mesh("LProfilTetMsh.xdmf")

Import nodes and displacements

The nodes and displacements can be imported by calling the function read_input_file

nodes, displacements = read_input_file("example_input.txt")

Mesh deformation

Lastly, the mesh can be deformed by calling the function deform_mesh

deform_mesh(mesh, nodes, displacements)

Corner Detection

Slightly modified and adapted implementation of:
3D INTEREST POINT DETECTION USING LOCAL SURFACE CHARACTERISTICS
WITH APPLICATION IN ACTION RECOGNITION,
Michael B. Holte, DOI: 10.1109/ICIP.2014.7026160

Usage

Import the corner detection function using

from cornerdetection_DoN.py import cornerdetection

Detect corners by calling the function on a given mesh

cornerdetection(mesh, "testoutput.txt", mode="angleSum", max_search_depth=2)

Where mesh is the mesh on which corners should be detected and "testoutput.txt" is the file name where the output should be written. Additionally, the two parameters mode and max_search_depth can be specified if needed. The parameter mode can either be "DoN" or "angleSum". These are two different methods of finding the maximum corner likelyness of a corner compared to its surrounding corners. The parameter max_search_depth specifies in a neighbourhood of how many nodes a maximum should be searched.
