trg [rlf | inl | fau | remeq] |
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.
Arguments
No argument. Triangulate the input data. Only the points are honoured.
inl
Convert a seismic inline to a triangulated seismic section.
rlf x | y | z sca scalefactor
Turn the scalar values into x | y | z coordinates as a relief using scalefactor to control the expansion.
fau faultlines
Make triangulated polydata in workspace faultlines within the fault polygon if the points are ordered counterclockwise. Otherwise it will be outside the fault polygon.
remeq
Remove triangles of equal z values. Thus the triangulation will only go between lines of unequal height.
