## SIVector3.MulByRotationInPlace

### Description

Right-multiplies this vector by the rotation r in place: this = this . r

### C# Syntax

    SIVector3.MulByRotationInPlace( SIRotation in_pRotation );

### Scripting Syntax

    SIVector3.MulByRotationInPlace( r );

### Parameters

Parameter | Type | Description
--- | --- | ---
r | SIRotation | Operand rotation

### Examples

#### VBScript Example

    dim v1, rotAngles, r1

    ' Create 3D vectors.

    set v1 = XSIMath.CreateVector3

    set rotAngles = XSIMath.CreateVector3

    ' Create Rotation.

    set r1 = XSIMath.CreateRotation

    v1.Set 1.0, 0.0, 0.0

    rotAngles.Set 0.0, 0.0, 0.7853981633974483

    r1.SetFromXYZAngles rotAngles

    v1.MulByRotationInPlace r1
