The Book
SteamAbout The Book
The Book turns the e-books you already own into 3D books. Hand it an EPUB, a PDF, CBZ, CBR, a wall of plain text or a folder of pictures, and it gets bound into a proper book — cover, spine, and pages you turn in a quiet reading room built for one thing only: reading.
Bring your own books

Reading Features
•
Guided Reading – Move the mouse to the right to move the camera along a predefined reading path from top to bottom and from left to right. When you reach the end of a page, the next page opens automatically. Move the mouse to the left to move backwards along the reading path.
•
Auto Reading – The camera automatically moves along the reading path.
•
Reading Speed Adjustment – Start a timer to record how long it takes you to read a page. Auto Reading will then use this time to determine how quickly to move through the page.
•
Shorten Reading Time – During Auto Reading, you can click the right mouse button if you have already finished reading the page but Auto Reading has not yet moved to the next page. The shorter time will then be used for subsequent pages.

Add / remove bookmarks. Maximum 99 per book.
