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
