---++LONI Triangle Model Format

This following description is obtained from LONI [[CCB.ShapeToolsLibrary][ShapeTools]] edu.ucla.loni.ccb.shapeio.tm.parser.TmAsciiShapeParser.

The conventional suffix for a LONI Triangle Model files is `.tm'.

Syntax:

<pre>nVertices  nFaces</pre>
{vertex coordinates, one per line, as X Y Z tuples}
{triangle face indices, three per line}

Note: The index of the third point of a triangle face
may have a "-" prefixed. This sign may indicate orientation.
It is ignored when the file is read.

Note: vertex indices start at 1, not 0. These are adjusted
by subtracting 1 before the face definitions are stored.
