I studied the on-line course(http://brickisland.net/DDGSpring2016/) by myself, and here are the screenshots of my implements(https://github.com/yaoyansi/DDGSpring2016) on some algorithms.
equally-weighted normal
area-weighted normals
angle-weighted normals
mean curvature normal
sphere-inscribed normal
Pick some vertexes and set the values, then construct the discrete Laplacian operator and solve the Poisson equation.
Perform one step of your mean curvature flow on the mesh to smooth the mesh
step size = 0.01
step size = 0.02
step size = 0.05
Decompose a vector field into 3 components: exact(curl-free), coexact(div-free), harmonic(curl-free&div-free)
top left, top right, down left, down right: vector field, exact, coexact, harmonic
