Definition: Laplacian Matrix for triangle meshes

Quick definition of the Laplacian matrix on a triangular mesh. I give an in depth explanation here.

Normal to an implicit surface

Gradient rules

Cheat sheet to differentiate expressions with the \( \nabla \) operator to compute gradients of various functions.

Contour lines

3d graph


To represent a 2D function \( z = f(x,y) \) one can draw a 3D surface. The higher the \(z\) value the higher the point on the surface (see above).
