In this assignment, groups implemented a differential representation of a surface mesh known as the Laplacian Mesh representation. This enabled a variety of applications, such as dragging points to make the mesh deform nonrigidly ("Laplacian mesh editing"), interpolating functions across surfaces, geometry filtering, mesh flattening, heat flow, and curvature estimation.
Results are below. Student analysis from their README files is provided in quotes where appropriate
"This makes sense considering what was said during class about the cotangent weights using angles, thus leading to better preservation during deformation and a visually smoother result."

"We decided to do texture mapping using the default chessboard on Chris's face... Coincidentally
this might be a good makeup idea for next Halloween"

"The minimal surface preserves the topology of handle when six anchors are set in the teapot mesh"

"This was a mesh which we encountered while implementing cotangent weights. It occurs when we pick anchors to raise Homer's arms and stationary points on Homer's chest and face, but not on Homer's feet. Cotangent weights on this configuration squeezes Homer. I thought this was a bug for the longest time, but its actually not. Good learning experience."
