Definition: Laplacian Matrix for triangle meshes


Definition of the Laplacian matrix and Laplace operator 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.

Introduction

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).

Curvature of a triangle mesh, definition and computation.
