Flash - Can I embed 3D inside Flash using Live 3D?
Possibly - this is a legacy feature (no longer supported) and may not work properly with later versions of Flash.
This technique is called FLASH+3D. Using a combination of CSS, Javascript, and DHTML, you can make the 3D model appear to be inside a Flash presentation.
You can control the 3D model from Flash the same way you control DHTML/Javascript from Flash. Using CSS/DHTML/Javascript, you can make the 3D model come and go as needed.
For more information, see Working with Flash in Chapter 4 of the User Guide. The User Guide is located in the Help menu of Live 3D CX.
