If you need the complete NASA data set go to -Thanks, Keith!A complete data set is available by cutting the bay out of the NASA model and pasting it into jon's model.

[entry type] [byte count] [data]The entries of interest are those of type 4. In this case, [byte count] is an integer indicating how many bytes of storage are needed to store the subsequent polygon description, assuming 4-byte floats; [data] is of the following format:
[polygon normal - x coordinate] [polygon normal - y coordinate] [polygon normal - z coordinate] [V1 - x coordinate] [V1 - y coordinate] [V1 - z coordinate] [V1 normal - x coordinate] [V1 normal - y coordinate] [V1 normal - z coordinate] [V2 - x coordinate] [V2 - y coordinate] [V2 - z coordinate] [V2 normal - x coordinate] [V2 normal - y coordinate] [V2 normal - z coordinate] ...Note that ([byte count]-12)/24 gives the number of vertices per polygon description. Incidentally, entries of type 6 guide the material choosing logic of the rendering algorithm.

Origin: at the so-called Orbiter Structural Reference Frame, which is
ahead of and "below" the nose. It is a standard for structural
measurement, and hence the accuracy of this model is the highest
among all models listed here.
Axes: X is positive towards the tail.
Y is positive towards the left wing, as seen from the nose.
Z is positive upwards (away from the bay).

The 15 trailing real numbers should be ignored. The surface ID is an
integer, unique within the file. The coordinates are real numbers.
[Location] is an arbitrary string shorter than 100 characters, which
does not contain any spaces; words are separated, instead, by
underscores. This format supports polygons with 3 or 4 vertices. A
3-vertex polygon is identified by forcing V4 to be the origin, i.e.
(0,0,0). Hence,

is a triangular surface. For a 4-vertex polygon, the four vertices are
ordered so that V1, V2, V4, V3 is a clockwise or anti-clockwise
ordering.

[number of vertices] [V1 - x coordinate] [V1 - y coordinate] [V1 - z coordinate] [V2 - x coordinate] [V2 - y coordinate] [V2 - z coordinate] ... [number of connecting lines or moves] [new 3D pen position - vertex ID] [color of line drawn; 0 for move] ...All numbers are integers, except for vertex coordinates which are real numbers. The color encoding scheme is unknown. The model is clearly a wireframe: it is not defined in terms of surfaces; instead it is a sequence of connecting lines. Hence, it does not qualify as a polygon mesh and may be inappropriate for solid modeling.
522 vertices. 1204 (variant 1) or 891 connecting lines (variant 2)
The shuttle model in "3dv25.zip" contains 1204 connecting lines. Oscar also provided me with a different version, containing 891 lines and possibly different coloring. At the end of that file, the following credits were present: "Rebuilt from a Purdue student project and included in 3dv 2.5 release (monochrome). This version colored and rotated by Francois Chew (c60b-2ci@weaver.berkeley.edu), and optimized with SHRINK."
