SHAPEFILES

Compiled by KD

Description

SHAPEFILES is a directory where, as its name suggests, shape files are stored. Out of the many shape files that can be stored in SHAPEFILES, SPC will only use one shape model at a time and that is SHAPE.TXT.

SHAPE.TXT is the main shape model that all of SPC uses. The first line is the Q size (between 8 and 512 in factor of 2 increments: 8, 16, 32, 64, 128, 256, 512). The shape is in the ICQ format, which is basically a 6 sided cube.

Each subsequent line gives the vector of the surface. Bob has made a new routine (equalize) that helps distribute the vectors evenly. The vectors are in Cartesian space (x, y, z).

SHAPE00.TXT is the "baseline" shape model. This can be used to keep track of how far the new shape gets from the starting shape. Usually, it is turned off part way through the mission by INIT_LITHOS.TXT.

A useful tip for the user is to use a symbolic link to specific the SHAPE.TXT. Thus, the user can keep a useful filename in the directory, but "link" that to SHAPE.TXT so SPC works.

cd SHAPEFILES
ln -s <realfile> SHAPE.TXT
