=== 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.e|lithos]] is used in the working directory. === How to Fix Landmarks === Once a problem landmark is identified, the executable [[lithos.e|lithos]] can be entered in the working directory to fix the landmark. 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.e|lithos]] executable: {{{ i EM0004 n n }}} The output of these commands looks like this: {{{ Current landmark = NONE Main Menu: Q 0123O IUCRSG NVAMBX DEPL FZH? i >i Input 6-character landmark name.[Q] EM0004 -0.31014 0.47683 -0.31113 0.29307 gc slope.pgm Check for more images? y[n] n Include a single image? y[n] n }}} |
