Another option is to make the wall:bedrock line have rays pointing at an angle (using a strict angle, not the angle of the line) but cutafter the line itself. But I think this might be extremely tricky to implement, and I can't think of an an easy way right now. The issue would be tight corners, where it is simply not possible to do all the clipping correctly. You could though define an area between the wall line itself, and a path that you calculate (using sharp corner avoidance) outside the wall line: https://therion.speleo.sk/wiki/metapost#shuttering_two_parallel_lines Then fill that area using a hatching pattern. That could actually work, and not be totally insane. However, your issue would be when you change from one line to another - at that point, the fill areas might not match up perfectly, and you might get unhatched gaps. It would only work for lines that you have redefined to have that cool fill pattern. Maybe someone will feel inspired to make a proof of concept... _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion
