I'm wondering if anybody has built code for adding cross-hatches to a 3D patch object? I see that this task is on Kesh Ikuma's todo list forhatchfill2 but have been unable to find anything on the web that actually does it. I tried to make it work with Neil Tandon'shatchfill but was unsuccessful. Thanks!
The hatching is defined in 2D usually. E.g. the pattern is determined by the angle between the X-axis and the lines. How do you want to expand this for the 3D case? What about using the texturemap method of asurface instead of apatch?
