Is there a fast way to do it, without using an outdated module?
If you're just accessing a single element of the array, there shouldn't be any speed problems with any version of Numeric or numpy. The speed will be limited by the surrounding Python code that decides what element to look at. What you use for the array will hardly make a difference at all -- even a pure Python list of lists would be just about as fast. The speed issues with Numeric/numpy only come into play when you're doing operations on whole arrays, such as adding all the corresponding elements of two arrays together. If you have a lot of objects to test against the terrain, it's likely you could find some way of using Numeric or numpy to test them all in one go. Done correctly, it would be *much* faster than looping over all the objects in Python. The speed difference between Numeric and numpy would be tiny by comparison. -- Greg
