Synopsis

PDX_BOOL gdx_NurbCurveInterIsTangent(long option, T_GDX_NURB_CURVE *cur1, double t1, T_GDX_NURB_CURVE *cur2, double t2, double tang_tol)

Purpose

Determine if the intersection of 2 GDX NURB Curves is tangent

Description

Given that two GDX NURB Curves intersect, determine if the intersections are tangent.

Input

option

Option (Not used)

cur1

The first GDX NURB Curve intersected

t1

The intersection parameter value for the first curve

cur2

The second GDX NURB Curve intersected

t2

The intersection paramter value for the second curve

tang_tol

The tangent tolerance defined as the difference in the angle between the tangent vectors at the point of intersection in radians

Return

      PDX_TRUE  = The intersection is tangent
      PDX_FALSE = The intersection is not tangent
