Flex - Rotate3D Effect
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
| S.N. | 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.

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, this will produce following result: [ Try it online ]
