Description

The information listed here goes in more depth about SHAPE.TXT than that listed in SHAPEFILES.

SHAPE.TXT is an output from ...

SHAPE.TXT is the shape model SPC uses where 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.

First line is Q (resolution). This gives the number of nodes for i and j. Multiple it by 6 coordinate vector spaces to fill out the entire region. Note: Q*Q*6 is the total number of nodes, and line entries in this file. A Q of 512 is the largest that we represent. It contains 1.5 million vertices and 56 MB uncompressed.

Second line and following: The location of a vertex in i, j, k space (Cartesian coordinates).
