Description:

Expert tool to evaluate partial derivatives of surface unit normal.

Syntax:
public static bool EvaluateNormalPartials(
Vector3d ds,
Vector3d dt,
Vector3d dss,
Vector3d dst,
Vector3d dtt,
out Vector3d ns,
out Vector3d nt
)
Parameters:
  • ns
  • Type: Rhino.Geometry.Vector3d
  • First partial derivative of unit normal. If the Jacobian is degenerate, ns is set to zero.
  • nt
  • Type: Rhino.Geometry.Vector3d
  • First partial derivative of unit normal. If the Jacobian is degenerate, nt is set to zero.
Returns:
Type: bool
True if Jacobian is non-degenerate, False if Jacobian is degenerate.
