Synopsis

PDX_MSGT gdx_SurfaceIsInfinite(long option, MDA_PTR gdx_surf_ptr, int *u_infinite, int *v_infinite)

Purpose

Check to see if Surface is infinite or not

Description

Checks to see if the GDX surface is infinite. u_infinite will be set to 1 if the surface is infinite in u direction. v_infinite will be set to 1 if the surface is infinite in v direction. Only four GDX surfaces can be infinite: .nf GDX_CONE GDX_CYLINDER GDX_EXTSURF GDX_PLANE .fi

Input

Surface is infinite in u direction

0

Surface is not infinite (bounded) in u direction.

v_infinite

1

Surface is infinite in v direction

0

Surface is not infinite (bounded) in v direction.
