h2. Name
*trg* — Triangulate point data
h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#FFFFAA}
*trg* \[*rlf | inl | fau | remeq*]
{panel}
h2. Description
Creates a triangle mesh from input points. The triangulation is of Delaunay type which tries to optimize the triangle with respect to equal sides.
h2. Arguments
{indent}No argument. Triangulate the input data. Only the points are honoured.{indent}
*inl*
{indent}Convert a seismic inline to a triangulated seismic section.{indent}
*rlf x | y | z sca* _scalefactor_
{indent}Turn the scalar values into x | y | z coordinates as a relief using scalefactor to control the expansion.{indent}
*fau* _faultlines_
{indent}Make triangulated polydata in workspace _faultlines_ within the fault polygon if the points are ordered counterclockwise. Otherwise it will be outside the fault polygon.{indent}
*remeq*
{indent}Remove triangles of equal z values. Thus the triangulation will only go between lines of unequal height.{indent}
