MATLAB: How to create a 3D mesh

Question

I want to create a 3D mesh but "initmesh" only works for 2D data. How do I create a mesh from 3D data?

Answer 1

Use the "generateMesh" function in the Partial Differential Equation Toolbox to generate a 3D mesh.

Refer to the following example that imports a 3D model, creates a mesh, and displays the mesh.

model = createpde;
importGeometry(model,'Torus.stl');
mesh = generateMesh(model);
[p,e,t] = meshToPet(mesh); %convert form of mesh
figure; pdemesh(mesh);
figure; pdemesh(p,e,t);
