Sets the value of this vector to the scalar multiplication of vector v1 by s and then adds vector v2: this = s*v1 + v2

C# Syntax

SIVector3.ScaleAdd( Double in_dScalar, SIVector3 in_pVector1, SIVector3 in_pVector2 );

Scripting Syntax

SIVector3.ScaleAdd( s, v1, v2 );


Parameter Type Description
s Floating Point value Scalar multiplicator of vector v1
v1 SIVector3 Operand vector
v2 SIVector3 Operand vector


VBScript Example

dim v1, v2, v3
' Create 3D vectors.
set v1 = XSIMath.CreateVector3(1.0, 2.0, 3.0)
set v2 = XSIMath.CreateVector3(3.0, 4.0, 5.0)
set v3 = XSIMath.CreateVector3
'v3 = 2.5 * v1 + v2
v2.ScaleAdd 2.5, v1, v2
