Lecture 8: Mesh Representations and Geometry Processing (8)

Simplification of meshes is a very important process for cutting down memory and improving rendering time. How do programs like Blender know what vertices to delete during the simplification process to best preserve the shape while reducing the number of vertices?

It's interesting we can downsample and upsample these meshes easily, and at the same time preserve or add new details of the original mesh. I am wondering though how can we determine the most reasonable representation of an object, balancing the space, time, and quality of the object? Does regularization help us achieve this goal? Also, how do we determine whether we can get the same details if we down sample for storage and then upsample to show a smoother image?
