# Synopsis

PDX_MSGT gdx_GetLinearApproxMesh(long option, int *u_paths, int *v_paths)

# Purpose

Get the current GDX linear approximation U and V mesh values.

# Description

Get the linear approximation U and V surface mesh values for the current GDX linear approximation workspace. 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.

# Input

## option

Not used

# Output

## 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
