Here are links to the data files used for the Java-Based Tensegrity Viewer and the Java3D-Based Tensegrity Viewer. The meaning of each line of text in a data file is determined by the first character on the line. The first character is either "#", "v" (stands for "vertex") or "l" (stands for "line"). Text lines starting with "#" are comments. Text lines starting with "v" are coordinate data for the points (a.k.a. vertices). Cartesian x, y and z values are given in floating-point format. After Tim Tyler kindly pointed out that some of the vertex data was duplicated, I consolidated the duplicates for the convenience of those applications where it is necessary. Text lines starting with "l" contain three integers indicating how geometric lines connect the points and what type of member the line represents: the first two integers are zero-based indexes into the vertex array, and the third integer is a "type" value. For tensegrities, geometric lines where the type (mod 8) is 1 are struts. The others are tendons.
