Topic: polygons, polyhedra, cell complexes and data structure for these. $n$-manifolds looks locally like $\mathbb{E}$. Further a $n$-manifold with boundary has points with neighboorhoods like a halfspace $\{x\in \mathbb{E}^n | x_n\geq 0\}$. Compact manifolds (with boundary) are the ones that … Continue reading lecture notes: 10.12.12
