Mental model when define and modify block boundary

Herb Schilling

Hello all,

We are writing a 2D structured gridding package for a specific application. One of the design issues has to do with whether the block boundaries are defined by just the boundary grid points or by a smooth curve on which the grid points lie.

There are many implementation pros and cons to this issue but from a user's perspective how do you like to think about the block boundary:

1. Just points that can be manipulated as points

2. Points on a smooth curve

Thanks in advance.
