Can I make a 3D book cover that rotates and place it on my WordPress website?
I didn't find any plugin to offer such functionality, but based on my knowledge, I know that Wordpress allows you to add custom HTML content, therefore use the BoxShot website. The result isn't free, but if you plan on using it, then you can embed it through HTML on your website.
Use the link to reach the website: http://boxshot.com/3d-pack/
You can use a flipbook for your website as well: http://codecanyon.net/item/real3d-flipbook-wordpress-plugin/6942587
