Synopsis

PDX_MSGT igeo_ApproxSetMesh(long option, int u_paths, int v_paths)

Purpose

Set the IGES surface approximation mesh

Description

Sets the approximation mesh to be used for linear approximation of surfaces if the surface is not set for facet approximation. The mesh is the count of constant (iso-parametric) surface curves in the U and V surface direction. The minimium mesh is 2 X 2 which approximates the surface boundary. By default, if the mesh property(406:5558) exists, the mesh values are used to define the UV path mesh.

Input

option

IGEO_IGNOREMESHPROP

Ignore the 406:5558 property and only use the input UV path mesh defintion.

u_paths

The number of U iso-parametric lines to approximate in V

v_paths

The number of V iso-parametric lines to approximate in U

Return

      IGEO_NOERR
      IGEO_INVALIDAPPXMESH
