I have a 300 x 300 grid of points each of which has an elevation associated with it.
I'd like to get a 3D print of the surface these points determine.
What is the simplest way of getting this done?
What I have is a 90000 item list of (x, y, z) points where z is the elevation of the point (x, y).
What tools could I use to convert this list into a format that shapeways can work on?
