C++

JScript

Copy

public virtual Vector3D[,] Evaluate( 
   double u, 
   double v, 
   int d 
)

Parameters

u: double

Parametric value along U direction

v: double

Parametric value along V direction

d: int

Vector3D[,]

Example

The following code fragment demonstrates how to compute the first 2 derivatives of the surface at the parametric value [0.25, 0.5].

C++

JScript

Copy

 Vector3D[,] SKL = mySurf.Evaluate(0.25, 2);
 
 Vector3D S   = SKL[0,0];
 Vector3D Su  = SKL[1,0];
 Vector3D Sv  = SKL[0,1];
 Vector3D Suu = SKL[2,0];
 Vector3D Suv = SKL[1,1];
 Vector3D Svv = SKL[0,2];
