# SHAPEFILES

## Description

This directory stores shape files. Out of the many shape files that can be stored in SHAPEFILES, SPC only uses one shape model at a time, SHAPE.TXT. It is the main shape model used throughout SPC.

The first line of SHAPE.TXT is the Q size (between 8 and 512 in a 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. 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 different it becomes from the starting shape. Usually, it is turned off partway through the mission by INIT_LITHOS.TXT.

• Use a symbolic link to specify SHAPE.TXT. This way, you can keep a useful filename in the directory, but "link" it to SHAPE.TXT so that SPC runs properly.

Here is a sample set of commands to show how to set up a link:

```cd SHAPEFILES
ln -s <realfile> SHAPE.TXT```

Here is a sample of a shape model:

```         512
-278.04003   278.04003   268.57872
-276.88948   278.59369   269.11354
