## SIVector3

Object Hierarchy | Related C++ Class: CVector3

### Description

A 3 element vector that is represented by double precision floating point x,y,z coordinates. In this API vectors are considered as row vectors as described in [Foley, J., and A. van Dam, Fundamentals of Interactive Computer Graphics, Addison-Wesley, Reading, MA, 1982]. This is important when you multiply a SIVector3 by a SIMatrix3 or a SIMatrix4.

### Examples

#### 1. VBScript Example

    dim v1

    ' Create 3D vector.

    set v1 = XSIMath.CreateVector3

    v1.x = 1.5

    v1.y = v1.x + 2.0

    v1(2) = v1.y - 1.0

#### 2. VBScript Example

    set cone = ActiveProject.ActiveScene.Root.AddGeometry("Cone", "NurbsSurface")

    ' set the transform with rotation values

    set transfo = XSIMath.CreateTransform

    transfo.SetRotationFromXYZAnglesValues 45.0, 0.0, -60.0

    ' get back the rotation euler values

    transfo.GetRotationXYZAnglesValues rotX, rotY, rotZ

    Application.LogMessage "rot X: " & rotX & " rot Y: " & rotY & " rot Z: " & rotZ
