Lecture 8: Mesh Representations and Geometry Processing (69)

Is there any reason why we would use triangle meshes vs rectangular meshes and what are the benefits/tradeoffs of using either?

I am thinking that rectangular are often preferred to triangles because they're easier to work with and in general have more consistent results such as smoother and more evenly distributed subdivision surface modifiers. Traingle are more used in more complex grids (unstructed), where which the neighborhood relationships are implicit, therefore requiring more storage design instead of simply using arrays.

I was wondering if the use of triangle meshes has anything to do with the fact that any surface have a triangulation (i.e., we can use n <= inf triangles to represent any surface)?
