Introduction

The Rotate3D class rotate a target object in three dimensions around the x, y, or z axes. The rotation occurs around the transform center of the target.

Class Declaration

Following is the declaration for spark.effects.Rotate3D class −

public class Rotate3D
   extends AnimateTransform3D

Public Properties

Sr.No Property & Description
1

angleXFrom : Number

The starting angle of rotation of the target object around the x axis, expressed in degrees.
2

angleXTo : Number

The ending angle of rotation of the target object around the x axis, expressed in degrees.
3

angleYFrom : Number

The starting angle of rotation of the target object around the y axis, expressed in degrees.
4

angleYTo : Number

The ending angle of rotation of the target object around the y axis, expressed in degrees.
5

angleZFrom : Number

The starting angle of rotation of the target object around the z axis, expressed in degrees.
6

angleZTo : Number

The ending angle of rotation of the target object around the z axis, expressed in degrees.

Flex Rotate3D Effect Example

Let us follow the following steps to check usage of Rotate3D Effect in a Flex application by creating a test application −

Step Description
1 Create a project with a name HelloWorld under a package com.tutorialspoint.client as explained in the Flex - Create Application chapter.
2 Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.
3 Compile and run the application to make sure business logic is working as per the requirements.

Following is the content of the modified mxml file src/com.tutorialspoint/HelloWorld.mxml.

<?xml version = "1.0" encoding = "utf-8"?>
<s:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"

               <s:Button label = "Apply Properties"
                  click = "applyRotateProperties()" />
            </s:VGroup>

            <s:Image id = "imageFlex"
               source = "http://www.tutorialspoint.com/images/flex-mini.png"
               height = "200" width = "200" />
         </s:Panel>
      </s:VGroup>
   </s:BorderContainer>
</s:Application>

Once you are ready with all the changes done, let us compile and run the application in normal mode as we did in Flex - Create Application chapter. If everything is fine with your application, it will produce the following result: [ Try it online ]
