use of maspack.util.NumberFormat in project artisynth_core by artisynth.

the class PolylineMesh method write.

 * followed by x, y, and z coordinates. Lines are printed next, starting
 * with the letter "f" and followed by a list of integers which gives the
 * indices of that line's vertices. An example of a simple three
 * point line is:
 *

 *    v 0.0 1.0 0.0
 *    v 0.0 0.0 1.0

 * {@link maspack.util.NumberFormat NumberFormat}.
 *
 * @param pw
 * PrintWriter to write this mesh to
 * @param fmt
 * format for writing the vertex coordinates. If <code>null</code>,
 * a format of <code>"%.8g"</code> is assumed.
 * @param zeroIndexed
 * if true, index numbering for mesh vertices starts at 0. Otherwise,
