Nonobtuse mesh

A nonobtuse mesh is a fancy way of saying a special kind of shape made out of a lot of smaller shapes. Imagine you have a piece of paper and you want to fold it into different shapes. A nonobtuse mesh is a shape that has no angles that are too big, like a pointy corner. It is a shape that is very smooth and round. When you make a nonobtuse mesh, you have to be very careful not to make any corners too pointy or too sharp. That way, the shapes fit together perfectly and look really nice. It's like building a puzzle with no pieces that stick out too far.
