A free app for Windows, by LULU Software.

With this app, you can easily read your PDFs on your desktop or laptop in a convenient way. To start using it, just download the app and open the file you want to view. You will be guided step-by-step to choose a mode that suits you best.

To enjoy a 3D view, you need to have a compatible device. To find out if you have a compatible device, you can go to the device settings in your system and look for the “PDF viewer” option. If it is not there, you will not be able to use the 3D view.
