Sharp Text in a 3D publication
In a 3D publication environment, text must be redrawn and character contours re-smoothed at any change of orientation. If the change of orientation is continuous then the font rendering engine needs to be able to output complete pages of refreshed text very fast and in real time. This can be done using assembly language to instruct the processor directly.
It is designed for use in a 3D publication model on either a 2D display screen or in 3D space. In a 3D graphical environment, the font-engine updates the text at every change of orientation. This means is that the text would refocus and sharpen in real-time when the reader changed their viewing position.
This method is the only way to ensure that small body text is always sharp, clear and readable at all times on a 3D page.
A real page in a print publication is rarely perfectly flat. In fact an open book, for example, always has a bend to every page. In this scenario, the 3D typesetter would determine the tangent of the curved page at the point that the character is to be drawn and make the minor adjustments to ensure it appears exactly as it would on a bended printed page, sharp, clear and perfectly positioned.
