When to Fix Landmarks
At the end of each tiling or iteration, a form of find_nofit (T or P) is used to check for bad landmarks.
A common find_nofit output will look soemthing like this:
EQ0004: cat 004.OOT EP0002: cat 005.OOT EP0003: cat 006.OOT EO0003: cat 007.OOT EN0003: * cat 008.OOT EN0004: * cat 009.OOT EM0003: . cat 010.OOT EM0004: * cat 011.OOT 132 deleted ! cat 132.OOTThe
The Four main types of find_nofit outputs are:
- ! - the landmark was deleted
- . - the landmark has overlaps
- (space) - the landmark has minor error (don't worry about it).
- * - the landmark has a major error and must be fixed.
All errors are worth recording, but the only output from find_nofit that warrants serious concern is *. Whenever a * is present in the find_nofit output the landmark that * is associated with must be fixed. To fix bad land marks lithos is used in the working directory.
How to Fix Landmarks
Once a problem landmark is identified, the executable lithos can be entered in the working directory to fix the landmark. The steps to do this are as follows:
1. The first major step in fixing a bad landmark is to select that landmark within lithos. As an example, the landmark EM0004 in the find_nofit output above has major errors. To select this landmark the following commands are entered in the lithos executable:
i EM0004 n n
The output of these commands looks like this:
Current landmark = NONE
