Usage

Overview

The cgalsimp2 utility is a surface mesh simplification utility built on the CGAL library (http://cgal.org). This tool utilizes the Lindstrom–Turk algorithm and decimate a surface mesh into a coarser downsampled surface. The output mesh is stored in a file named "out.off".

Please see https://doc.cgal.org/latest/Surface_mesh_simplification/ for details regarding the underlying algorithm.

Options

This program accepts the following input parameters:

input.off|(required)

The input surface mesh in the OFF format

keepratio|(required)

A 0-1 floating point number denoting the percentage of edges that will be preserved (1-keepratio is the percentage of edges that will be decimated. If keepratio is negative, it triggers the "LindstromTurk placement" policy; otherwise, it uses a mid-point placement policy by clapsing an edge to its mid-point.
