VCGetCurrentEntityNormal3D

Version:

1.2

Description:

Returns the normal vector to the current 3D entity.

Declaration:

C/C++

extern "C" void WINAPI VCGetCurrentEntityNormal3D(short* iError, Point3D* nV);

Delphi

procedure VCGetCurrentEntityNormal3D(var iError: Smallint; var nV: Point3D); stdcall;

ActiveX/COM

Function GetCurrentEntityNormal3D() As IVCPoint3D

Parameters:

nV - the normal vector to the current entity.

Notes:

Many calculations based on 3D geometry require the use of the normal vector. The normal vector is a perpendicular to the 3D face and is represented by x, y and z coordinates that define the direction of the vector.
